问题描述

用户如何在运行模式下更改Telerik组件的ChartSeries的颜色和类型？

您好

我将所有类型的ChartSeriesType放在一个组合框中。用户如何改变它的类型（Bar，Line，...）？

Bellow line有错误：

chartSerie1.Type = Telerik.Charting.ChartSeriesType +。 + my_ChartSeriesType.SelectedValue.ToString（）;



如何更改每个系列的颜色？



谢谢非常

推荐答案

1。更改系列的类型

您必须创建预期系列类型的新实例

1. Change the type of the series
You have to create a new instance of the expected series type

SeriesMapping seriesMapping = new SeriesMapping();
seriesMapping.LegendLabel = "Product Sales";
seriesMapping.SeriesDefinition = new SplineSeriesDefinition();   // The expected type (SplineSeriesDefinition, BarSeriesDefinition, ...) you have to do a switch-case/if clause to differentiate or you use reflection to create the type dynamically
seriesMapping.ItemMappings.Add( new ItemMapping( "Month", DataPointMember.XValue ) );
seriesMapping.ItemMappings.Add( new ItemMapping("Quantity", DataPointMember.YValue));
radChart.SeriesMappings.Add( seriesMapping );
