Can't render region labels as HTML with jVectorMap - javascript

I wrote my code down to a small fiddle: http://jsfiddle.net/V8dyd/266/
I am able to render region labels as strings on the map but unable to render them as HTML.
$(function(){
var Jsondata = {
LK: " Region : Asia, Feedback : 228, Good : 34.00%, Normal : 33.00%, Bad : 30.00% ",
IN: "Total Responses : 228"
};
var map = $('#map').vectorMap({
map: 'world_mill_en',
zoomMin: 1,
zoomMax: 1,
regionLabelStyle: {
initial: {
fill: '#B90E32'
},
hover: {
fill: 'black'
}
},
labels: {
regions: {
render: function (code) {
if (code==="LK") {
var a = Jsondata[code];
var array = a.split(',');
var s = "<html><body><div><small>" + array[0] +"</small><br><small>" + array[1] + "</small><br><small>" + array[2] + "</small><br><small>" + array[3] + "</small></div</body></html>";
var htmlObject = document.createElement('div');
htmlObject.innerHTML = s;
return htmlObject;
// return s
}
}
}
}
});
});

The labels are rendered using svg TEXT-Tags and do not allow HTML.
In the current version this is not supported but i used a Hook in the Region Function for realize line breaks:
https://github.com/bjornd/jvectormap/blob/master/src/region.js
Like this:
jvm.Region = function(config){
var bbox,
text,
offsets,
labelDx,
labelDy;
this.config = config;
this.map = this.config.map;
this.shape = config.canvas.addPath({
d: config.path,
'data-code': config.code
}, config.style, config.canvas.rootElement);
this.shape.addClass('jvectormap-region jvectormap-element');
bbox = this.shape.getBBox();
myHook(bbox, text, offsets, config);
return false;
...
}
function myHook(bbox, text, offsets, config){
// Create your own Label like this
text = this.getLabelText(config.code);
if (this.config.label && text) {
offsets = this.getLabelOffsets(config.code);
this.labelX = bbox.x + bbox.width / 2 + offsets[0];
this.labelY = bbox.y + bbox.height / 2 + offsets[1];
this.label = config.canvas.addText({
text: text,
'text-anchor': 'middle',
'alignment-baseline': 'central',
x: this.labelX,
y: this.labelY,
'data-code': config.code
}, config.labelStyle, config.labelsGroup);
this.label.addClass('jvectormap-region jvectormap-element');
}
}
Thats not the best way but maybe it helps you!

User memory limit exceeded in GEE

I started using GEE recently. I wanted to apply the non-parametric Mann-Kendall method to a collection of Sentinel-1 images. However there is a memory error in the code and this is my problem. Link code:https://code.earthengine.google.com/4bf1dbbcd116c8e3f5c584fbb45e8c19

Chart.js How to sum the values in a pie chart and display them in the header

I have a pie chart that shows how many people have registered by area. What I need to do is sum the pie slices and display the total in the header/title of the pie chart.
I am using chart.js and c#.

}
In the image below I need the total which is 3,009 to be displayed beside Attendees by Area.
Pie Chart
Figured it out. I used a function to add all the values for people registered and then passed that to my function that draws the pie chart.
In my case statment:
case 4:
groupData = defineGroupDataArray();
var totalAttendees = 0;
$.each(groupValue.Data,
function(statIndex, statValue) {
groupData.labels.push(statValue.Description);
groupData.datasets[0].data.push(statValue.Count);
groupData.datasets[0].backgroundColor.push(seriesColors[statIndex]);
totalAttendees += statValue.Count;
});
drawAttendeesByAreaChart(animate,totalAttendees);
break;
In the draw chart function:
function drawAttendeesByAreaChart(animate,totalAttendees) {
$("#attendbyarea").remove();
$("#attendbyarea-container").append('<canvas id="attendbyarea"></canvas>');
$("#attendbyarea-header").text("Attendees by Area ("+ $.number(totalAttendees) +")");
...rest of code...
};

How to display custom tooltips on line chart using Rickshaw Library

I am developing a realtime graph system which will display the memory usage at particular time using data from json file . I am using Rickshaw Library which accepts tool tip in numeric type else the hard coded value supplied as a property to graph .
I have a json object as :
[
{
"memory": 444.08203125,
"memoryInfo": {
"rss": 444.08203125,
"vsize": 1271.125
},
"cpu": 0.2,
"url": [
"/admin/company/approved"
],
"time": "2/12/2016, 10:42:09 AM"
},
...
...
]
I want to show in tool tip at particular time what was the url served by server so that i can get proper information like which route is consuming more memory.
I will share my so far js code with you so that it will be better to understand .
script.js
$(function(){
var json = null;
console.log("Document Ready");
$.ajax({
url: 'data.json',
type: 'get',
success: function (data) {
console.log("Got data");
json = data
drawGraph()
}
});
var interval = 250;
//function to use from populating new values to graph
var getMemory = function(index) {
return json[index].memory
}
var getUrl = function(index) {
return json[index].url[0]
}
var getToolTip = function(){
console.log("getting tooltip")
return "api/login"
}
var drawGraph = function(){
// instantiate our graph!
graph = new Rickshaw.Graph( {
element: document.getElementById("chart"),
width: 900,
height: 400,
renderer: 'line',
interpolate:'basis',
series: new Rickshaw.Series.FixedDuration([{ name: 'memory' ,color:'steelblue',tooltip:"/api/login"}], undefined, {
timeInterval: interval,
maxDataPoints: 500,
timeBase: new Date().getTime() / 1000,
})
})
//tooltip is hardcoded should be dynamic when fetching each object from json
graph.render();
// get Recent log data using socket and feed it to graph
var i = 0;
var iv = setInterval( function() {
i++
var data = { memory: getMemory(i)};
graph.series.addData(data);
graph.render();
}, interval );
//hover details
var hoverDetail = new Rickshaw.Graph.HoverDetail( {
graph: graph,
formatter: function(series, x, y) {
var date = '<span class="date">' + new Date(x * 1000).toUTCString() + '</span>';
var swatch = '<span class="detail_swatch" style="background-color: ' + series.color + '"></span>';
var content = swatch + series.tooltip + ": " + parseInt(y) + '<br>' + date;
console.log(series)
return content;
}
});
}
});//jQuery
Can you give us some further information regarding your problem/error?
From a quick look that I had, your tooltips (Rickshaw.Graph.HoverDetail) won't be able to render because you are asking in formatter for inputs "series,x,y" and you haven't set each element of the data array to have a x and y value.
example:
data: [ { x: 0, y: 5 }, { x: 1, y: 10 } ]
Take a look at rickshaw example here.

plotting realtime data and turning on and off data series using flot api

I am using flot charts. I want to plot chart which is updated per second and also want to add the feature of turning off and on the data series.
I am able to make it work but has problems which I did not expect, like color of one series change when other series is turned off; other is when I update the array of data series the charts seems to move but it removes element from the right,at the same time the new value is plotted on the right hand side ...

I am making use of code available in flot charts examples.Where am I going wrong ??
Thank you ?
Problem 1 : Color updating every time a checkbox was checked or unchecked
Reason: Every time the checkbox click event was triggered,some how the color used to get updated
Solution : Removed setTimeout(getNextDataset,1000); call from the function plotAccordingToChoices()
Problem 2: The data elements are removed from the right instead of left.
Reason : (Very dumb) Data was coming in descending order and I was using pushing data in that order only.So latest point was at location 0 of the array and oldest point was at location n-1.And I was removing (n-1)th point.
Solution : Replaced push in the beginning with unshift().Did the magic :P
