Serial Chart in amCharts showing different beahaviour - javascript

I am using amCharts for my App. Recently I updated it from version 3.17.0 to 3.20.6.
In my App, I have used export with capture method to capture image as below:
if (window.fabric) {
clearTimeout(interval);
// CAPTURE CHART
chart.export.capture({}, function() {
// SAVE TO JPG
this.toPNG({}, function(base64) {
//some code
});
});
}
}, 10);
In my serial chart with Chart cursor, It was working fine as below in previous version. See image:
After updating version it shows weird behavior: ChartCursor gone, and on dragging cursor it is drawing line on Chart.
I have checked on amChart website, I have correctly set everything.
What can be wrong here?
If I will disable chart.export.capture, it' will working fine.
Here is my code to set properties chart:
"type": "serial",
"theme": "none",
"pathToImages": "resources/javascript/amcharts/images/",
"marginTop": 1,
"marginBottom": 1,
"autoMarginOffset": offsetM,
//left hand side space between container and chart
"zoomOutButtonRollOverAlpha": 0.15,
"zoomControl": {
"zoomControlEnabled": true,
"backgroundAlpha": "0.15",
"backgroundColor": "#000000"
},
"dataProvider": valueChartData,
"columnWidth": 1,
"categoryField": "date",
"categoryAxis": {
"minPeriod": "DD",
"parseDates": true
},
"export": {
"enabled": false,
"menu": []
}
for exporting and cloning chart:
var interval = setInterval(function() {
if (window.fabric) {
clearTimeout(interval);
// CAPTURE CHART
main.pageContainerBulkMarketing.bulkmarketing.pageContainerBMReports.reports.chart["export"].capture({}, function() {
// SAVE TO JPG
this.toPNG({}, function(base64) {
somewhere.OpenedTabGrpClone = "";
somewhere.OpenedTabGrpClone = base64;
});
});
}
}, 10);
Note: I have observed one thing: It is adding one canvas tag over our chart div, it is like:
<canvas class="upper-canvas " style="position: absolute; width: 802px; height: 360px; left: 0px; top: 0px; -moz-user-select: none; cursor: crosshair;" width="802" height="360"></canvas>
UPDATE: Here I have added jsfiddle But, here it is working fine, I took this time to figure out that why it's not working my side; result :none.

Simple do this
1) Check your library links and plugin code , may it interfer with other js or plugin .
2) Also Test your code with live amchart libraries.
3) if every thing fine and working set Z-index by -1 for canvas tag.

Highchart.js: use bootstrap glyphicons instead of symbols on contextbutton

How can i use bootstrap glyphicons instead of "regular" symbols in the contextbuttons of Highcharts. Going to exporting > buttons > contextButton.
I have added some glyphicon in the className propery, but the symbol shows up instead. Is there any way to override this?
Here is an example JSON object for Highcharts:
{
"chart": {
"type": "column",
"renderTo": "periodChart"
},
"title": {
"text": "Verkoop per periode"
},
"xAxis": {
"categories": ["2015", "2016", "2017"]
},
"yAxis": {
"title": {
"text": "Aantal verkochte producten"
}
},
"exporting": {
"buttons": {
"contextButton": {
"align": "right",
"symbol": "menu",
"height": 22,
"width": 24,
"y": 0,
"x": 0,
"className": "glyphicon glyphicon-print",
"enabled": true
}
}
},
"series": [{
"borderColor": "#555",
"data": [{
"name": "2015",
"y": 6121.0
}, {
"name": "2016",
"y": 6172.0
}, {
"name": "2017",
"y": 4943.0
}],
"name": "Aantallen per jaar (P/s)"
}]
}
I have added the following packages to my html, along with bootstrap and jquery:
<script src="http://code.highcharts.com/stock/highstock.js"></script>
<script src="http://code.highcharts.com/modules/exporting.js"></script>
Edit: when i leave the symbol property empty ("") then nothing shows up. Not using the property at all will result in the default "menu" symbol.
EDIT
The post before the edit contained only the information how to add a regular image as a background to the context button which wasn't the actual answer for this question.
Here I used glyphicon as a charcter in the text of te button: http://jsfiddle.net/kkulig/LoLtm8bn/
I haven't found a way to completely disable the symbol in the context button. The workaround for this is to hide it but the space reserved for it still remains there.
I ended up using the approach from Full text button example in this API record: https://api.highcharts.com/highcharts/exporting.buttons.contextButton.text (contextButton disabled, exportButton used instead).
Live demo: http://jsfiddle.net/kkulig/np80zf58/
END OF EDIT
Context button is an SVG element so you need to use defspattern for this:
JS:
events: {
load: function() {
var chart = this,
renderer = chart.renderer;
var pattern = renderer.createElement('pattern').add(renderer.defs).attr({
width: 1,
height: 1,
id: "image1",
patternContentUnits: 'userSpaceOnUse'
});
renderer.image('https://www.highcharts.com/samples/graphics/sun.png', 0, 0, 24, 24).add(pattern);
}
}
CSS:
// hide the default symbol
.highcharts-button-symbol {
display: none
}
// use a new one
.highcharts-button-box {
fill: url(#image1)
}

echarts Media queries not working with Bootstrap (carousel)

I have a bootstrap carousel with 2 slides. Both the slides uses bootstrap grids of 2x2 to display charts on them. They are working fine , however I am trying to implement responsive media queries and can't seem to make it work. I used baseOptions and media options to define but the charts do not load up and the console doesn't show any error.
I have tried to define the <div> container with inline style width and height i.e. style="width: 100%;height:400px;" and I have also tried to define the width and height in CSS like so-
.mychart {
width: 100%;
height: 400px;
}
The javascript looks like below.
<div id="chart1" style="width: 100%;height:400px;"></div> //with inline style
<div id="chart1" class="mychart"></div> //with CSS class
var myChart1 = echarts.init(document.getElementById('chart1'));
var lpnArr = [101, 43, 10, 250];
option = {
title : {
text: 'My data Pie',
subtext: 'Data as of last batch',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{b} : {c} ({d}%)"
},
legend: {
orient : 'vertical',
x : 'left',
data:['Processed','Unprocessed','In RIB','Errors']
},
color: ['#4bc14f','#ff7f50','#da70d6','#d8316f'],
toolbox: {
show : true,
feature : {
mark : {show: false},
dataView : {show: false},
magicType : { show: false},
dataZoom : { show : false},
restore : {show: true},
saveAsImage : {show: true}
}
},
calculable : true,
series : [
{
name:'Processed',
type:'pie',
radius : ['50%', '70%'],
startAngle : 230,
center: ['35%', '50%'],
itemStyle : labelFormatter, //custom formatter
data: lpnArr //load chart with data array lpnArr
}
]
}
var mediaQuery = [
{
option: {
series: [
{
radius: ['50%', '70%'],
center: ['35%', '50%']
}
]
}
},
{
query: {
minAspectRatio: 1
},
option: {
series: [
{
radius: ['50%', '70%'],
center: ['35%', '50%']
}
]
}
},
{
query: {
maxAspectRatio: 1
},
option: {
series: [
{
radius: ['50%', '70%'],
center: ['50%', '35%']
}
]
}
},
{
query: {
maxWidth: 500
},
option: {
series: [
{
radius: ['50%', '70%'],
center: ['50%', '35%']
}
]
}
}
];
myChart1.setOption({baseOption : option,
media : mediaQuery});
if I use it without the media query it works just fine. like this
myChart1.setOption(option);
Using the media query, as per the documentation along with baseOptions and media, the charts simply don't load and it doesn't show me any error in the console as well, so I am not sure if I am using it correctly or not.
By the way, I also have this in the end of the script to be able to resize the charts when the window is resized but then I realized that this is not truly responsive -
$(window).on('resize', function(){
myChart1.resize();
});
The bootstrap chart elements are <div> elements within other div with a class of BS container-fluid. The carousel code can be found in this JSFiddle.
Media query was introduced in echarts version 3, whereas I have been using version 2 and thus it wasn't working. It's extremely odd that using media with version 2 doesn't show any kind of error, neither does baseOption show any error so I was left scratching my head. Documentation isn't clear enough to say that media queries is only supported in version 3. So after scouring through the code and GitHub threads for hours and trying out all their js versions I came to this conclusion.
The downside of using version 3 echarts is that it is missing the "Tree" chart type and it's a lot more pickier than any prior version. Also, it's twice as much slower than version 2.

Google Table Chart Styling

It seems like the styling on google table chart not working very well. Even on their own examples on the webpage https://developers.google.com/chart/interactive/docs/examples (Customized Table Example) does not work? Like the golden border? I canĀ“t see any?
I want to style my own google table chart and remove the border around the cells? Anyone how can get that to work I would be so happy. My code look like this.
CSS:
.remove-cell-border{
border: none;
}
chartService.js
var drawTableChart = function (data, type) {
var cssClassNames = {
'headerRow': "header-grey-font",
'tableRow': "remove-cell-border",
'headerCell': "remove-cell-border",
'tableCell': "remove-cell-border",
};
var chartObject = {
"type": type,
"display": false,
"data": data,
"options": {
"allowHtml": true,
"isStacked": "true",
"fill": 20,
"displayExactValues": false,
"cssClassNames": cssClassNames
},
"formatters": {}
};
return chartObject;
};
return {
drawTableChart: drawTableChart
};
The thing was that some other CSS was overriding my border-style. So now it is working when I changed my CSS to !important.
.remove-cell-border{
border: none !important;
}

amCharts - document.getElementsByClassName(...)[0] is undefined

I'm using amCharts to display a map. I'm aiming to change the color of a specify country using Javascript.
I do use the following line to change the color inside my web browser :
document.getElementsByClassName("amcharts-map-area-FR")[0].setAttribute("fill", color);
But when I use it inside my html page, this does not work.

Hope this problem can be solved !
Thanks !
Your code to manipulate fill color of the area is correct. However, it executes immediately on page load. At that point the map is still initializing, meaning there's no such element yet, hence it not working.
There are a number of ways to go about it.
If you just need to load the map with certain areas (countries) colored, you could do that with map's config:
"dataProvider": {
"map": "worldLow",
"getAreasFromMap": true,
"areas": [ {
"id": "FR",
"color": "#00FF00"
} ],
"images": [ {
"top": 40,
"left": 60,
"width": 80,
"height": 40,
"pixelMapperLogo": true,
"imageURL": "http://pixelmap.amcharts.com/static/img/logo.svg",
"url": "http://www.amcharts.com"
} ]
}
If that is not acceptable, or if you need to manipulate the map after it's built, I suggest you use map's API functions (getObjectById() to get area object, then validate() to refresh it) to manipulate area colors, rather than CSS.
You would also need to ensure that map is initialized before doing so. We can use init event for that.
Consider the following code:
AmCharts.makeChart("map", {
"type": "map",
// ...
"listeners": [{
"event": "init",
"method": function(event) {
var area = event.chart.getObjectById("FR");
area.color = "#000000";
area.validate();
}
}]
});
Here's a working example.
You could use the same event to manipulate color of the area using your CSS code, however I strongly suggest using API functions. While manipulating CSS directly may work, the changes might be reset when there's something going on on the map, such as when you hover the area.

jsPlumb Endpoint offset

First of all let me say I'm kind of new to jQuery and I'm definately new to jsPlumb altough I have checked the official documentation I've not been able to get a solution to this problem.
I have 2 draggable div elements that each have an endpoint so I can connect them to each other. The problem is when I make the connection and then drag any of the div elements around the arrow image I'm using isn't properly placed where it should be (I'm using ["RightMiddle", "LeftMiddle"] for the anchors).
Is there a way to make the images stick at the middle-right (or left) side of the div elements and not get out of place?
Here's the jsFiddle link for what I have so far, and here's the code:
$(document).ready(function () {
jsPlumb.draggable($('.table'), {
containment: '#schema'
});
var endpointOptions = {
isSource: true,
isTarget: true,
endpoint: ["Image", {
url: "http://i43.tinypic.com/1z31ac2.gif"
}],
style: {
fillStyle: 'gray'
},
maxConnections: -1,
connector: ["Flowchart", {
curviness: 5
}],
connectorStyle: {
lineWidth: 3,
strokeStyle: 'gray'
},
anchors: ["RightMiddle", "LeftMiddle"],
scope: "gray"
};
var ep01 = jsPlumb.addEndpoint("container0", endpointOptions);
var ep02 = jsPlumb.addEndpoint("container1", endpointOptions);
jsPlumb.connect({
source: ep01,
target: ep02
});
});
To make the images stick at the middle-right (or left) side of the div elements, instead of specifying both RightMiddle and LeftMiddle you can simply specify any one.
anchors: "RightMiddle", // For your image Right position suits the best
