Large Numbers on Chart

[Barry]

I have a requirement to have numbers in the millions and billions on a chart and when I put them on the RadCartesianChart they end up looking like this: 5E+08 (for 500,000,000). Is there a way to get the chart to show 500,000,000? Or 25,000,000,000?

Hi Barry,

We support this functionality through the label format feature of RadChartView's axes. Setting a label format like this:

<telerik:LinearAxis LabelFormat="###,###,###" />

will override the scientific notation you've come across and will show 500 000 000 instead of 5E+08. This formatting is the standard one used by the .NET framework, as outlined in this topic on MSDN.

Hi,

Is there a simple way to format values in a way, it was done by default in previous varions of Charts. I mean e.g.:

600
800
1k
1,2k

or:
500 k
1 mil
1,5 mil

and so on?

Best regards

Hi Marcin,

In order to achieve this you will need to plug in some custom logic that will apply different format on the axis labels depending on their value. This can be done by specifying a custom LabelTemplate that uses a converter to do the formatting:

<telerik:LinearAxis>
<telerik:LinearAxis.LabelTemplate>
 <DataTemplate>
  <TextBlock Text="{Binding Converter={StaticResource LabelFormatConverter}}"/>
 </DataTemplate>
</telerik:LinearAxis.LabelTemplate>
</telerik:LinearAxis>

I have attached a sample project demonstrating this.
I hope this helps.
