WPF饼图调色板禁用随机笔刷再生

Question

I have a pie chart, every time I update ( Re-assign to a new collection ) my itemssource the colors changes randomly , All I Want is to keep the first palette.

the pie chart is from System.Windows.Controls.DataVisualization.Charting from the assembly System.Windows.Controls.DataVisualization.ToolKit

Answer 1

A quick research shows me that the System.Windows.Controls.DataVisualization.ChartingChart.Chart has a Property Palette which stores by default 15 different ResourceDictionary each section of the PieChart will use the next Colors (or Styles or whatever is strored in the Dictionary). If you want to keep the same Color you could add (15 - n) sections where n is the number of sections that was displayed. And then Change the Itemssource to whatever you want.
