Hi Raghupathy,

Have you seen our Legend API Overview article? It shows you the legend API, including templating the legend items.

We also have an advanced tutorial on legend item templating to introduce custom fields into the legend. Perhaps this helps?

enter image description here

If not, please explain clearly what you need and we will do our best to help.

Best regards,
Andrew

I want to show the legends outside of the chart surface i can do that for GetLegendDataFor="AllSeries" but i can't do that for GetLegendDataFor="AllVisibleSeries" i got a error message saying that 'Set property 'Abt.Controls.SciChart.ChartModifiers.LegendModifier.GetLegendDataFor' threw an exception.' Line number '67' and line position '39'. I create the chart when my application launch after when the user select the y axis value then only polt the graph.I think this is the problem.also how can i change the legend color it always white??

Hi Raghupathy, I believe there was a bug reported with GetLegendDataFor ... see https://www.scichart.com/questions/question/how-programatically-add-legend-to-chart. It was fixed in build 5199. Can you double-check the latest nightly build and let us know if it resolves the problem? If not, please let me know. One of the team will investigate. For your other question - legend color white, why not create a new question, we will answer it asap. Best regards, Andrew
