How to point the range(dataClasses) for 2nd index in data using highcharts?

I have plotted a heatmap using highchart , but i wanted to give color range for y axis ie 2nd index in the data array but it takes 3rd index automatically.
Below is the jsfiddle code.
Links for my code
colorAxis: {
dataClasses: [{
from: 0,
to: 10,
color: 'rgb(191, 27, 0)'
},{
from:10,
to:30,
color:'rgb(234, 100, 96)'
},{
from:30,
to:100,
color:'rgb(242, 201, 109)'
},{
from:100,
color:'rgb(98, 158, 81)'
}]
},
series: [{
name: 'Sales per employee',
borderWidth: 1,
data: [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24], [0, 4, 67], [1, 0, 92], [1, 1, 58], [1, 2, 78], [1, 3, 117], [1, 4, 48], [2, 0, 35], [2, 1, 15], [2, 2, 123], [2, 3, 64], [2, 4, 52], [3, 0, 72], [3, 1, 132], [3, 2, 114], [3, 3, 19], [3, 4, 16], [4, 0, 38], [4, 1, 5], [4, 2, 8], [4, 3, 117], [4, 4, 115], [5, 0, 88], [5, 1, 32], [5, 2, 12], [5, 3, 6], [5, 4, 120], [6, 0, 13], [6, 1, 44], [6, 2, 88], [6, 3, 98], [6, 4, 96], [7, 0, 31], [7, 1, 1], [7, 2, 82], [7, 3, 32], [7, 4, 30], [8, 0, 85], [8, 1, 97], [8, 2, 123], [8, 3, 64], [8, 4, 84], [9, 0, 47], [9, 1, 99], [9, 2, 31], [9, 3, 48], [9, 4, 91]],
dataLabels: {
enabled: true,
color: '#000000'
}
}]
The actual data is in below format
data: [[0, 0, 10], [0, 1, 19]]
Now range is plotted on the base of 2nd index ie 10,19 but i want to plot based on 1st index ie 0,1.

Change the default name of the property (of point object) that'll be used to compute the color :
Highcharts.seriesTypes.heatmap.prototype.colorKey = 'x'; // 'value' by default

Redraw issue in Highcharts 3D Scatter Chart

Here I'm working on Highcharts 3D Scatter chart, based on the sample jsfiddle. In the fiddle,I used to redraw the chart, while emptying the div which contain chart,scatter points get removed ,but the 3D container is not removed.And hence chart is not redrawing.
javascript code :
var chart = new Highcharts.Chart({

Please suggest a method to redraw 3d scatter chart.

Moving the color setting outside your method will fix your problem. See more information about that here: http://forum.highcharts.com/highcharts-usage/pie-char-uncaught-typeerror-a-indexof-is-not-a-function-t33161/
I also moved chart outside the method so that destroy() could be called on it. This will prevent memory leaks.
var chart;
// Give the points a 3D feel by adding a radial gradient
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) {
return {
radialGradient: {
cx: 0.4,
cy: 0.3,
r: 0.5
},
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.2).get('rgb')]
]
};
});
function scatterChart(Data) {
// Set up the chart
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
type: 'scatter',

Create Density Heatmap Chart using Jquery with array of data

I got stuck while creating the density heatmap chart using highcharts.js.
I am able to create a heatmap chart but the heatmap chart does not fit to the entire width. I am expecting the my heatmap chart to look like the below screenshot. Any help will be much appreciated. Also, please suggest any other plugins to meet the expected behavior.
Thanks in Advance.

tooltip: {
headerFormat: 'Temperature<br/>',
pointFormat: '{point.x:%e %b, %Y} {point.y}:00: <b>{point.value} ℃</b>'
}
}]
});
The code is in JSFiddle here.

From my personal experiences with Highcharts, you have to explicitly define a width for your container div, whether that's a percentage or a fixed pixel width. max-width seems to be treated as an option (often overlooked) vs. a command. I hope this is helpful for you.

How to insert values in bars (flotcharts)

I have some problems to show some values in bars. I want a chart like this: Example. I don't know what I'm missing in here.
$('#myModalChart').on('shown.bs.modal', function (e) {
var data = [{
label: "Foo",
data: [
[2],
[3, 9, 12],
[6, 0, 3],
[9, 11, 12],
[12, 0, 1],
[15, 0, 2],
[18],
[3, 12, 12],
[9, 12, 12]
]
},
{
label: "Bar",
data: [
[2],
[3, 0, 5],
[6, 3, 7],
[9, 4, 11],
[12, 1, 3],
[15, 2, 5],
[18]
]
},
{
label: "Tree",
data: [
[2],
[3, 5, 9],
[6, 7, 15],
[9, 0, 4],
[12, 3, 13],
[15, 5, 17],
[15, 17, 17],
[12, 13, 13],
[6, 15, 15],
[18]
]
},];
var options = {
series: {
bars: {
show: true,
barWidth: 1
}
},
xaxis: {
align: "center",
ticks: [
[3.5, 'text1'],
[6.5, 'text2'],
[9.5, 'text3'],
[12.5, 'text4'],
[15.5, 'text5']
]
}
};
var plot = $.plot("#chart2", data, options)
});
I want a chart like this, with labels in it. And I wish have in all of them.
What I'm missing?

You have to create and place the data value labels yourself. How to do this can be seen in this answer.
I created a fiddle adjusting it to your code. Only the first data series (foo) has labels for now. you will have to adjust the position. The relevant code:
$.each(plot.getData()[0].data, function (i, el) {
if (el.length > 1) {
var o = plot.pointOffset({
x: el[0],
y: el[1]
});
$('<div class="data-point-label">' + el[1] + '</div>').css({
position: 'absolute',
left: o.left + 4,
top: o.top,
'text-align': 'center',
display: 'none'
}).appendTo(plot.getPlaceholder()).fadeIn('slow');
}
});
But you may also have to cleanup your data. You have multiple data points with the same x values (which means bars behind / in front of each other which leads to some being invisible). Take a look at the side-by-side and stack plugins on the flot plugin page.

Flotr2 colors not working

I just got a book called Data Visualization With Javascript by Stephen A. Thomas, and I'm working through the exercises. The first chapter is on Flotr2. Here is what the book told me to do:
var wins = [[[0, 13], [1, 11], [2, 15], [3, 15], [4, 18], [5, 21], [6, 28]]];
var wins2 = [[[0,28], [1,28], [2, 21], [3,20], [4,19]]];
var years = [[0, "2006"], [1, "2007"], [2, "2008"], [3, "2009"], [4, "2010"], [5, "2011"], [6, "2012"]];
var teams = [[0, "MCI"], [1, "MUN"], [2, "ARS"], [3, "TOT"], [4, "NEW"]];
window.addEventListener('load', function() {
Flotr.draw(document.getElementById('chart2'), wins2, {
title: "Premier League Wins (2011-2012)",
colors: ['#89afd2', '#1d1d1d', '#df021d', '#0e204b', '#e67840'],
bars: {
show: true,
barWidth: 0.5,
shadowSize: 0,
fillOpacity: 1,
lineWidth: 0
},
yaxis: {
min: 0,
tickDecimals: 0
},
xaxis: {
ticks: teams
},
grid: {
horizontalLines: false,
verticalLines: false
}
});
});
Now the only difference between this and what was in the book is that the book told me to do window.onload, and I used addEventListener instead. The book says that this should make a bar graph with multiple colors (the colors listed) but all my bars are the same color, which is the first color listed. I've tried everything, but nothing seems to make it work. Has anyone else encountered this problem with Flotr2? I'm using the latest version, so is it just a problem with Flotr2 that's new since the book came out? Or am I doing something wrong?

try this.
var wins2 = [[[0,28]],[[1,28]],[[2,21]], [[3,20]],[[4,19]]];

I think it may have to do with your arrays...
var wins2 = [[[0,28], [1,28], [2, 21], [3,20], [4,19]]];
That makes an array of 1 array that has 4 arrays. So flotr is seeing you only have 1 index, which is why it uses just 1 color.
try
var wins2 = [[0,28], [1,28], [2, 21], [3,20], [4,19]];
