How to style images in highcharts flags?

In my chart, I show the user pictures for their comment date, so the users can read the comments in a tooltip using these icons. It seems like soundcloud charts. I did it using flags type and I set the shape variables as user picture url for each data item.
But I want to add also colorized border for each icons. I know, there is lineWidth and lineColor config in flags type but it doesn't work with images, it works only with default shapes flag, circlepin or squarepin.
I tried to use shape as flag and to add user images as background image, but It doesn't work.

In SVG you can not set border for the images, you need to create rect around the image: http://jsfiddle.net/xuL76rkL/1/
For example you can use load and redraw events to manage those rects, code:
var H = Highcharts;
function drawBorder() {
var chart = this;
H.each(chart.series[1].points, function(p) {
var bbox,
rect,
fontSize = 13, // it's used as default font size offet, even for the images
dim = 32; //width and height for the image
if(p.graphic) {
if(p.rectangle) {
p.rectangle.destroy();
}
bbox = p.graphic.getBBox();
rect = chart.renderer.rect(p.plotX - dim/2, p.plotY - dim/2 - fontSize, dim, dim).attr({
"stroke": "black",
"stroke-width": 2,
"fill": "transparent"
}).add(chart.series[1].markerGroup);
p.rectangle = rect;
}
});
}
$('#container').highcharts('StockChart', {
chart: {
events: {
load: drawBorder,
redraw: drawBorder
}
},
...
});

You can set an image with the shape option:
Example: shape: "url(/assets/my_image.svg)"

Customizing Chart.js troubleshoot

Have some trouble with Chart.js
1) is it possible to move bottom labels on top of the chart?
2) is it possible to hide left labels with first grey line?
3) is it possible to set up permanent tooltips(to show temperature) on every point instead of hover tooltips?
Here is my chart http://jsfiddle.net/JohnnyJuarez/ojc09hv4/:
<canvas id="weeksChart" width="651" height="335"></canvas>
var dayTemperatureArray = [-5, 14, 15, 15, 17, 18, 19, 21, 22, 25, 24, 20, 19, 16];
var nightTemperatureArray = [-10, 4, 5, 6, 8, 11, 12, 15, 17, 15, 13, 12, 11, 9];
var dataWeeks = {
labels: ["16.02", "17.02", "18.02", "19.02", "20.02", "21.02", "22.02", "23.02", "24.02", "25.02", "26.02", "27.02", "28.02", "01.03"],
datasets: [
{
label: "Days temperature chart",
fillColor: "transparent",
strokeColor: "rgba(244, 6, 6, 1)",
data: dayTemperatureArray
},
{
label: "Nights temperature chart",
strokeColor: "#3f6bf5",
data: nightTemperatureArray
}
]
};
var ctx = document.getElementById("weeksChart").getContext("2d");
window.weeksChart = new Chart(ctx).Line(dataWeeks, {
responsive: true,
pointDot: true,
datasetStrokeWidth: 0.5,
scaleSteps: 2,
scaleLabel: "<%=value + '°'%>",
tooltipTemplate: "<%= value %>",
showTooltips: true
});
Thanx a lot in advance!
p.s. please avoid jquery, if it's possible :-)

Let's start with the easiest one first
2) is it possible to hide left labels with first grey line?
I assume you meant the y axis labels. You can set the scaleShowLabels option to false in the chart options to hide the y axis labels
window.weeksChart = new Chart(ctx).Line(dataWeeks, {
scaleShowLabels: false,
...
1) is it possible to move bottom labels on top of the chart?
I assume you mean the x axis labels. Chart.js doesn't have a direct option to do this. However you can hide the actual x axis labels and draw the x axis labels at the top of the chart by yourself.
Again, Chart.js doesn't have an option to hide x axis labels, but luckily there is an option to control the scale font color. Just set it to transparent and your original x axis labels are now hidden!
window.weeksChart = new Chart(ctx).Line(dataWeeks, {
scaleFontColor: "transparent",
...
Now the drawing of the x axis labels at the top of the chart. To save us the trouble of extending the chart, we can add a post animation event handler and do this in that, like so
window.weeksChart = new Chart(ctx).Line(dataWeeks, {
onAnimationComplete: function () {
animationComplete.apply(this)
}
...
with
var animationComplete = function () {
var self = this;
Chart.helpers.each(self.datasets[0].points, function (point, index) {
self.chart.ctx.font = Chart.helpers.fontString(self.fontSize, self.fontStyle, self.fontFamily)
self.chart.ctx.textAlign = 'center';
self.chart.ctx.textBaseline = "middle";
self.chart.ctx.fillStyle = "#666";
self.chart.ctx.fillText(point.label, point.x, self.scale.startPoint);
});
};
We just loop through all points in one of the dataset and add the labels (scale.startPoint is the top edge of the chart area)
Note - why do we set the font, alignment, etc. every iteration? That's for when we add the tooltips.
3) is it possible to set up permanent tooltips(to show temperature) on every point instead of hover tooltips?
The first step would be to actually show the tooltips. This is fairly simple, though a bit tedious. We loop through all the x axis point, build the label (by going through each dataset) and then construct a tooltip (fortunately, we can use Chart.MultiTooltip function for this.
We add it into the same loop we used to construct the new x axis labels. Since we need to color our tooltips, we need to get and store the set of colors in an array (which we pass on to the MultiTooltip function - we need to do this only once, so we take it out of the loop.
The modified animationComplete function is now this
var animationComplete = function () {
var self = this;
var tooltipColors = []
Chart.helpers.each(self.datasets, function (dataset) {
tooltipColors.push({
fill: dataset.strokeColor,
stroke: dataset.strokeColor
})
});
Chart.helpers.each(self.datasets[0].points, function (point, index) {
var labels = []
var total = 0;
Chart.helpers.each(self.datasets, function (dataset) {
labels.push(dataset.points[index].value)
total += Number(dataset.points[index].y);
});
new Chart.MultiTooltip({
x: point.x,
y: total / 2,
xPadding: self.options.tooltipXPadding,
yPadding: self.options.tooltipYPadding,
xOffset: self.options.tooltipXOffset,
fillColor: self.options.tooltipFillColor,
textColor: self.options.tooltipFontColor,
fontFamily: self.options.tooltipFontFamily,
fontStyle: self.options.tooltipFontStyle,
fontSize: self.options.tooltipFontSize,
titleTextColor: self.options.tooltipTitleFontColor,
titleFontFamily: self.options.tooltipTitleFontFamily,
titleFontStyle: self.options.tooltipTitleFontStyle,
titleFontSize: self.options.tooltipTitleFontSize,
cornerRadius: self.options.tooltipCornerRadius,
labels: labels,
legendColors: tooltipColors,
legendColorBackground: self.options.multiTooltipKeyBackground,
title: point.label,
chart: self.chart,
ctx: self.chart.ctx,
custom: self.options.customTooltips
}).draw()
self.chart.ctx.font = Chart.helpers.fontString(self.fontSize, self.fontStyle, self.fontFamily)
self.chart.ctx.textAlign = 'center';
self.chart.ctx.textBaseline = "middle";
self.chart.ctx.fillStyle = "#666";
self.chart.ctx.fillText(point.label, point.x, self.scale.startPoint);
});
};
It looks complex, but all we are doing is passing a options that we copy from the chart instance options to the MultiTooltip function.
The tooltips all show up when the animation is complete. HOWEVER, once you move your mouse over the chart they all up and disappear! That's because the chart instance listens for multiple events to decide whether to start checking if tooltips should be shown - one of these is mousemove (and that causes it to redraw the chart, wiping out all our hard drawn tooltips and, if we are lucky, it draws a tooltip based on the point our mouse is hovering over)
This is a configurable option. So, all we have to do is remove all such events.
window.weeksChart = new Chart(ctx).Line(dataWeeks, {
tooltipEvents: []
...
Working fiddle - http://jsfiddle.net/fuodxsfv/
Unless your chart is wide enough, you will have tooltips (mostly the middle 2 ones) overlap (of course you could incorporate logic into the above loop to handle that), but anyhoo, those were actually meant to be tooltips!

How to stop Spin.js from other js file

i need help
Actually in my work i need to implement spin.js and block UI in a jqgrid. This is ok when i put the code in the same file and function, but i want to call a method from other JS file, and hear is where my problem. The spin.js and block UI start, then block UI stop with unblock but the spin.js still running.
Here is my code:
In BeforeRequest() in jqgrid i call one method
$.pui.common.loaderAnimationON("pane-content");
this method have this code
loaderAnimationON: function (div) {
var opts = {
lines: 13, // The number of lines to draw
length: 20, // The length of each line
width: 10, // The line thickness
radius: 30, // The radius of the inner circle
corners: 1, // Corner roundness (0..1)
rotate: 0, // The rotation offset
direction: 1, // 1: clockwise, -1: counterclockwise
color: '#000', // #rgb or #rrggbb or array of colors
speed: 1, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: '50%', // Top position relative to parent in px
left: '50%' // Left position relative to parent in px
};
var target = document.getElementById(div);
var spinner = new Spinner(opts).spin(target);
$.blockUI({
blockMsgClass: "gridProjectsLoader",
message: null
});
return spinner;
},
in gridComplete() i call other method
$.pui.common.loaderAnimationOFF("pane-content");
this method have this code
loaderAnimationOFF: function (div) {
var target = document.getElementById(div);
var spinner = $.pui.common.loaderAnimationON();
spinner.stop(target);
$.unblockUI();
}
Anyone can help me?
Thanks guys

You should use the same object to start and stop it. You can use global variables anywhere (just another .js)
Check this jsFiddle. It's stop spinner after 3 secs.
http://jsfiddle.net/YX7dy/8/
spinner=loaderAnimationON('Spin');
setInterval(function(){spinner.stop();},3000);

How to display page loading indicator using spin.js

I am learning how to use Spin.js so that a loading indicator (the spinner) can be shown while the web page is loading.
I got it working but I am not sure whether I am calling the spin/stop in the proper page lifecycle. Is it possible to show the spinner before $(window).ready ?
<script type="text/javascript">
var spinner;
$(window).ready(function loadingAnimation() {
var opts = {
lines: 13, // The number of lines to draw
length: 7, // The length of each line
width: 4, // The line thickness
radius: 10, // The radius of the inner circle
corners: 1, // Corner roundness (0..1)
rotate: 0, // The rotation offset
color: '#000', // #rgb or #rrggbb
speed: 1, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: 'auto', // Top position relative to parent in px
left: 'auto' // Left position relative to parent in px
};
var target = $("body")[0];
spinner = new Spinner(opts).spin(target);
});
window.onload = function() {
spinner.stop();
};
For the working example, please see http://sgratrace.appspot.com/industry.html

I created an object to control the spinning:
Rats.UI.LoadAnimation = {
"start" : function(){
var opts = {
lines : 13, // The number of lines to draw
length : 7, // The length of each line
width : 4, // The line thickness
radius : 10, // The radius of the inner circle
corners : 1, // Corner roundness (0..1)
rotate : 0, // The rotation offset
color : '#000', // #rgb or #rrggbb
speed : 1, // Rounds per second
trail : 60, // Afterglow percentage
shadow : false, // Whether to render a shadow
hwaccel : false, // Whether to use hardware acceleration
className : 'spinner', // The CSS class to assign to the spinner
zIndex : 2e9, // The z-index (defaults to 2000000000)
top : $(window).height()/2.5, // Manual positioning in viewport
left : "auto"
};
var target = $("body")[0];
return new Spinner(opts).spin(target);
},
"stop" : function(spinner){
spinner.stop();
}
};
When the DOM is loaded, I start spinning:
$(document).ready(function(){
// Once the DOM is loaded, start spinning
spinner = Rats.UI.LoadAnimation.start();
pageUI();
});
When the entire page is loaded, I stop spinning:
$(window).load(function(){
// Once the page is fully loaded, stop spinning
Rats.UI.LoadAnimation.stop(spinner);
});
What's the difference between window.onload vs $(document).ready()

How to make a spinner work using Spin.js?

Hello guys,
I am new at JavaScript and after tons of research on the Internet and failed attempts on implementing a spinner I decided to ask you.
I am using Spin.js ( http://fgnass.github.com/spin.js/#v1.2.6 ). It seems to be an great tool, but I simply cannot make it work. My question is what I doing wrong? I cannot really figure it out. Any help will be much appreciated. Thank you so much.
Here is my piece of code:
<script src="Scripts/Spin.js" type="text/javascript"></script>
<script type="text/javascript">
function spinnerInit() {
var opts = {
lines: 13, // The number of lines to draw
length: 7, // The length of each line
width: 4, // The line thickness
radius: 10, // The radius of the inner circle
corners: 1, // Corner roundness (0..1)
rotate: 0, // The rotation offset
color: '#000', // #rgb or #rrggbb
speed: 1, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: 'auto', // Top position relative to parent in px
left: 'auto', // Left position relative to parent in px
visibility: true
};
var target = document.getElementById('spinnerContainer');
//target.style.display = "block";
var spinner = new Spinner(opts).spin(target);
}
</script>
<script type="text/javascript">
$(document).ready(function () {
$('#btnPerformSave').click(function () {
spinnerInit();
});
});
</script>
<div id="spinnerContainer" class="spinner" style="width: 100%; height: 150%;
position: absolute; z-index: 100; background-color: Gray;
left: 0; top: 0; bottom: 0;right: 0">
</div>

Try replacing
var target = document.getElementById('spinnerContainer');
var spinner = new Spinner(opts).spin(target);
with
$('#spinnerContainer').after(new Spinner(opts).spin().el);
You need to append the html element the spin method creates to the dom
Here is an example to get you started http://jsfiddle.net/5CQJP/1/

I am not sure if this question ever got answered, but for those who are still looking for an answer:
I found out that I needed to move the javascript underneath the spinnerContainer div. I believe this would also work if you put the javascript in an onload event. Here is what I did:
<div id="spinnerContainer" class="spinner" style="width:100px;height:100px;background-color: Gray;">
</div>
<script src="Scripts/Spin.js" type="text/javascript"></script>
<script type="text/javascript">
var opts = {
lines: 13, // The number of lines to draw
length: 7, // The length of each line
width: 4, // The line thickness
radius: 10, // The radius of the inner circle
corners: 1, // Corner roundness (0..1)
rotate: 0, // The rotation offset
color: '#000', // #rgb or #rrggbb
speed: 1, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false, // Whether to use hardware acceleration
className: 'spinner', // The CSS class to assign to the spinner
zIndex: 2e9, // The z-index (defaults to 2000000000)
top: 'auto', // Top position relative to parent in px
left: 'auto' // Left position relative to parent in px
};
var target = document.getElementById('spinnerContainer');
var spinner = new Spinner(opts).spin(target);
</script>

Here is my answer. Works great.
//Declare Script
<script src="Scripts/spin.js" type="text/javascript"></script>
<button id="btnSearchClick">Search</button>
//Displays Loading Spinner
<div id="loading">
<div id="loadingcont">
<p id="loadingspinr">
</p>
</div>
</div>
<script type="text/javascript">
//On button click load spinner and go to another page
$("#btnSearchClick").click(function () {
//Loads Spinner
$("#loading").fadeIn();
var opts = {
lines: 12, // The number of lines to draw
length: 7, // The length of each line
width: 4, // The line thickness
radius: 10, // The radius of the inner circle
color: '#000', // #rgb or #rrggbb
speed: 1, // Rounds per second
trail: 60, // Afterglow percentage
shadow: false, // Whether to render a shadow
hwaccel: false // Whether to use hardware acceleration
};
var trget = document.getElementById('loading');
var spnr = new Spinner(opts).spin(trget);
//Go another page.
window.location.href = "http://www.example.com/";
});
</script>

Try this:
var target = document.getElementById('spinnerContainer');
//target.style.display = "block";
var spinner = new Spinner(opts);
If you use jQuery:
$(target).html(spinner.el);
If not, as in the documentation:
target.innerHtml = '';
target.appendChild(spinner.el);
I didn't try this but it should work. If a problem occurs, just let me know.

I know this is way late but I am curious if you ever got this to work. I'll tell you one dumb thing I was doing for a bit and didn't realize it. I was making the spinner the same color as the background it would be showing up against and that's why I couldn't see it. Also I used JQuery as seen here https://gist.github.com/its-florida/1290439
Worked like a charm
