Attached is an image of the problem I'm currently having.
Attached is an example of the issue manually created with JSFiddle
https://jsfiddle.net/ekjrLsz2/
My goal is to have each of the blocks be next to each other without all the space in-between like the default demos for the heatmap show.
I can get it to work correctly if the data is going 1 by 1, for example; 1,2,3,4,5,6
But if the data is going 5,10,15,20, etc... then you get what you see in my attached image.
So to be more clear the X direction is going 1 by 1 in my demo image and shows without spacing, the Y direction however has the large spacing since the data does not have numbers 21,22,23,24 or the space inbetween every 5 so to speak.
Below is the code I use to generate the chart.
Highcharts.setOptions({
lang: {
decimalPoint: '.',
thousandsSep: ','
}
});
Highcharts.chart('heatmap-container', {

I have tried pointInterval and tickInterval with no luck so far.
The simplest way to have your points next to each other (without any spaces) is to give them x attributes without skipping any number, e.g 1,2,3,4...
Why don't you try to do it this way?
Demo:
https://jsfiddle.net/BlackLabel/39vx468s/
To skip the empty spaces between points you can use breaks functionality.
API references:
https://api.highcharts.com/highcharts/xAxis.breaks
Demo:
https://jsfiddle.net/BlackLabel/et4kryvz/
xAxis: {
breaks: [{
from: 0.5,
to: 1.5,
breakSize: 0
}]
}
There is also another solution, which uses colsize and rowsize properties. Thanks to that you can avoid using the breaks altogether this way and it even works with floating-point data.

Let's say we have two high charts - heat maps (can be more in future). Check it like below jsfiddle.
http://jsfiddle.net/xzq5bzy5/1/
<div id="container" style="height: 400px; min-width: 310px; max-width: 800px; margin: 0 auto"></div>
<div id="container2" style="height: 400px; min-width: 310px; max-width: 800px; margin: 0 auto"></div>
What I want if I hover on first cell of first high charts. It should simultaneously hover the second high chart first cell and both should show data in their respective tool-tips.
I have tried to search but I didn't find anything. Let me know if I need to add anymore information.
Here is a basic example using synchronised-charts highchars demo:
/*
The purpose of this demo is to demonstrate how multiple charts on the same page can be linked
through DOM and Highcharts events and API methods. It takes a standard Highcharts config with a
small variation for each data set, and a mouse/touch event handler to bind the charts together.
*/
/**
* In order to synchronize tooltips and crosshairs, override the
* built-in events with handlers defined on the parent element.
*/
$('#container').bind('mousemove touchmove touchstart', function(e) {
var chart,
point,
i,
event;
for (i = 0; i < Highcharts.charts.length; i = i + 1) {
chart = Highcharts.charts[i];
event = chart.pointer.normalize(e.originalEvent); // Find coordinates within the chart
point = chart.series[0].searchPoint(event, true); // Get the hovered point
if (point) {
point.highlight(e);
}
}
});
/**
* Override the reset function, we don't need to hide the tooltips and crosshairs.
*/
Highcharts.Pointer.prototype.reset = function() {
return undefined;
};
/**
* Highlight a point by showing tooltip, setting hover state and draw crosshair
*/
Highcharts.Point.prototype.highlight = function(event) {
this.onMouseOver(); // Show the hover marker
this.series.chart.tooltip.refresh(this); // Show the tooltip
this.series.chart.xAxis[0].drawCrosshair(event, this); // Show the crosshair
};
for (var i = 0; i < 2; ++i) {

I've a heat map using Highcharts where I'm facing some issues with text clippings.
When I add a label on the colorAxis the text gets clipped:
colorAxis: {
min: 0,
minColor: '#FFFFFF',
maxColor: Highcharts.getOptions().colors[0],
labels: {
format: '{value} test test test'
},
}
I've only added the colorAxis.labels.format property.
See my example here:

It's based/forked on this official Highchart sample:

HighCharts does have its quirks in the legend layout. You have to explicitly set the width, i.e.
legend: {
...
width: 140,
...
},
Found a way to make it dynamic, based on a post by TorsteinHonsi on GitHub. The code basically measures the width of the label and redraws the chart. See if it suits your needs.

to read dynamic data from my Controller using JSON how can I do that?
You need a method in your controller which provides you the information you want.
public String getData(){
int[,] ints = new int[,] { {1,1},{2,2},{3,3} };
var json = Newtonsoft.Json.JsonConvert.SerializeObject(ints);
}
In your view you can get it like this:
$.get("/Controller/getData", null, function (data) {
thisismydata = data;
});
If you want to do this async take a look at $.ajax(). You can find more information here.
I don't really know how to do this.
I need to change background color of this highcharts chart:
http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/polar-spider/
But I don't seem to be able to do so - there doesn't seem to be any clear place to put the background color setting?
I've tried to write many different values in this section:
chart: {
polar: true,
type: 'line'
},
But it didn't do anything ( it occasionally broke this script ).
Do I need to change it somewhere in the included .js files? Or can it be done from the level of this loaded script?
JS is really confusing. Can anyone help me?
Take a look at the Highcharts API here: https://api.highcharts.com/highcharts/chart.backgroundColor and you will see it's a property of the chart object that can take a solid color:
{
chart: {
backgroundColor: '#FCFFC5',
polar: true,
type: 'line'
}
}
Or Gradiant:
{
chart: {
backgroundColor: {
linearGradient: [0, 0, 500, 500],
stops: [
[0, 'rgb(255, 255, 255)'],
[1, 'rgb(200, 200, 255)']
]
},
polar: true,
type: 'line'
}
}
There is a backgroundColor tag you can use: (http://jsfiddle.net/aeP4E/)
chart: {
polar: true,
type: 'line',
backgroundColor:'blue'
},
That's you want
`
chart: {
polar: true,
type: 'line',
backgroundColor:'rgba(255, 255, 255, 0.1)'
}
`
Demo
You can data: [[0, 0, true], you can hide value by 'false' and you can set your gradient
by
colorAxis: {
min: 0,
stops: [
[0, '#5DBA76'],
[0.4, '#ffff00'],
[0.8, '#F30000']
],
minColor: '#ff0000',
maxColor: '#ffff00'
},
Thanks :)
you can hide value by 'false'
data: [[0, 0, false], [0, 1, 2], [0, 2, 3], [0, 3, 4], [0, 4, 5], [1, 0, 2], [1, 1, 4], [1, 2, 6], [1, 3, 8], [1, 4, 10], [2, 0, 3], [2, 1, 6], [2, 2, 9], [2, 3, 12], [2, 4, 15], [3, 0, 4], [3, 1, 8], [3, 2,12], [3, 3, 16], [3, 4, 20], [4, 0, 5], [4, 1, 10], [4, 2, 15], [4, 3, 20], [4, 4, 25]
