I'm am replacing my dot net charting with KendoUI. I'm showing a Score Distribution chart. I want all of the bars to be the same color except the bar with the median score and the Legend. How do I color a single bar a unique color? How would I color the Legend this new color?
Below is my old dotnet charting bar chart and below that is the new KendoUI chart I'm trying to replace it with. I just need to get that coloring right and we'll be in business. Any help is appreciated.
Update: I'm leaving the answer below this line intact in case there are those out there who are using an older version, but per a later comment, KendoUI now allows you to override styles for individual points in a series.
I don't believe you can, in the current version. That said, you can hack your way around the limitation.
You'll need to create two data series - one for your highlighted data, and one for everything else. Add both to you chart, and set them to stacked.
Here's a jsFiddle I put together to illustrate: http://jsfiddle.net/LyndsySimon/9VZdS/. It depends on KendoUI's CDN, so if it breaks in the future I apologize.
Here is the Javascript for reference:
$(function() {
var dataset = new Array(1,2,3,null,5,6);
var highlighted = new Array(null,null,null,4,null,null);
$('#chart').kendoChart({
theme: 'metro',
seriesDefaults: {
type: 'column',
stack: true
},
series: [
{
name: 'Not Highlighted',
data: dataset,
color: '#609'
},
{
name: 'Highlighted',
data: highlighted,
color: '#f03'
}
]
})
});
Another way you can do it at runtime is using function which returns color.
API reference
Here is an example code:
<div id="chart"></div>
<script>
$("#chart").kendoChart({
series: [{
data: [1, 2],
color: function(point) {
if (point.value > 1) {
return "red";
}
// use the default series theme color
}
}]
});
</script>
