I am working with high charts, I have a set of controls on a web page that allows the user to select months and locations. The issue is if they select a location that has no data. So lets say they select January and Hawaii but there is no data for Hawaii in January. Nothing will be displayed at all, but I would like the axis to appear along with the labels.
NOTE: I am trying to create a heatmap so I don't want to see the minimun color when there is no data.
A value of null seems to work. You can change your tooltip to not display if the value is null too: http://jsfiddle.net/SheldonNeilson/95um4x0q/1/

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({

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.
Demo: https://jsfiddle.net/87tL3ogh/1/
So I have two charts on the same page and I am using boost for both of these graphs. I wish to allow zooming and if I do a zoom then the line chart disappears. The data appears to still be there as the mouse over shows the data.
See this fiddle:

i < n;
i = i + 1, x = x + 36e5
) {

}

}
if (i % 50000 === 0) {
spike = 10;
} else {
spike = 0;
}
arr.push([

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:
http://jsfiddle.net/dennismadsen/7sp8ddpq/1/
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.

I want to change
var data1 = [
[0, 4], [1, 8], [2, 5], [3, 10], [4, 4], [5, 16], [6, 5], [7, 11], [8, 6], [9, 11], [10, 30], [11, 10], [12, 13], [13, 4], [14, 3], [15, 3], [16, 6]
];
var data2 = [
[0, 1], [1, 0], [2, 2], [3, 0], [4, 1], [5, 3], [6, 1], [7, 5], [8, 2], [9, 3], [10, 2], [11, 1], [12, 0], [13, 2], [14, 8], [15, 0], [16, 0]
];
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.
