[Solved] Sorting the legend

[Gifer]

Hi,

I created a pie chart using SerieDefinition. The data is sorted by max-min algorithm. However I would like to display the legend using a different sort. In other words I'd like to show the data in the legend in a different order than the one in the pie. Is this possible?

Thank you.

Hi Gifer,

You can set reverse order for Legend Items by turning on the ReverseLegendItemsOrder property of the Legend like this:

RadChart1.DefaultView.ChartLegend.ReverseLegendItemsOrder = true;

To be able to make more customizations on Legend Items you should turn off UseAutoGeneratedItems property and manually generate them. This is described in our help topic - http://www.telerik.com/help/silverlight/radchart-features-chart-legend.html#Manual_Legend_Items_Generation.

Thank you Evgenia,

I have another question. Is it possibile to disable the interactivity between legend and pie chart only when the value is 0% ?

Hello Gifer,

Could you be more specific about what you want to show/ hide on the Legend and Chart Area as I couldn't understand your question. Do you want to make invisible all Legend Items which Pie Slice Values are 0%?

The interactivity between pie and legend is enabled, so when the user clicks on one item in the legend the text gets bold and the rispective slice explodes. Now, I would like to keep this effect just for the slices that are not 0% and disable it when the value is 0%. In other words, when the user clicks on the item in the legend, if the data value is 0, the slice will not explode. However if the user clicks on a item which value is different from 0 then the slice explodes.  

Thanks

Hello Gifer,

I'm afraid that this is not supported with our RadChart for Silverlight as Selection feature is applied to all Items - there is no way to set some condition whether some of them can be clicked and some can not.
