Set a custom color sequence for a JavaFX pie chart.

PieChartWithCustomColors.java

import javafx.application.Application;
import javafx.collections.*;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.chart.*;

public class PieChartWithCustomColors extends Application {
  @Override public void start(Stage stage) {
    ObservableList<PieChart.Data> pieChartData = FXCollections.observableArrayList(
      new PieChart.Data("Grapefruit", 13),
      new PieChart.Data("Oranges",    25),
      new PieChart.Data("Plums",      10),
      new PieChart.Data("Pears",      22),
      new PieChart.Data("Apples",     30)
    );

    final PieChart chart = new PieChart(pieChartData);
    chart.setLegendVisible(false);

    stage.setScene(new Scene(chart));
    stage.show();

    applyCustomColorSequence(
      pieChartData, 
      "aqua", 
      "bisque", 
      "chocolate", 
      "coral", 
      "crimson"
    );
  }

  private void applyCustomColorSequence(ObservableList<PieChart.Data> pieChartData, String... pieColors) {
    int i = 0;
    for (PieChart.Data data : pieChartData) {
      data.getNode().setStyle("-fx-pie-color: " + pieColors[i % pieColors.length] + ";");
      i++;
    }
  }

  public static void main(String[] args) { launch(args); }
}

Answer to StackOverflow question: Javafx change PieChart color

but the bottom labels colors still did not change?

does there is any way to change them too

thank you...

I also can not change the subtitle color.
But, thank you for help me!
Sorry for my english, i'm learning, hehehe.

I think you can use this after initializing scene :
try
{
scene.getStylesheets().add("chart.css");
}
catch (Exception ex)
{
System.err.println("Cannot acquire stylesheet: " + ex.toString());
}

then :
use your style chart like this :
.data0.chart-pie
{
-fx-pie-color: #505FA3;

}
.data1.chart-pie{
-fx-pie-color: #9999ff;
}

Just remove applyCustomColorSequence( pieChartData, "aqua", "bisque", "chocolate", "coral", "crimson" ); and add this lines:

Scene scene = new Scene(chart);
scene.getStylesheets().add("/css/pie-chart-custom-colors.css");

stage.setScene(scene);

Now create a new .css file and add this code:

.default-color0.chart-pie { -fx-pie-color: #ffd700; }
.default-color1.chart-pie { -fx-pie-color: #ffa500; }
.default-color2.chart-pie { -fx-pie-color: #860061; }
.default-color3.chart-pie { -fx-pie-color: #adff2f; }
.default-color4.chart-pie { -fx-pie-color: #ff5700; }

This way you will change the color of each element also you can use color names like this:

.default-color0.chart-pie { -fx-pie-color: blue; }
.default-color1.chart-pie { -fx-pie-color: red; }
.default-color2.chart-pie { -fx-pie-color: green; }
.default-color3.chart-pie { -fx-pie-color: yellow; }
.default-color4.chart-pie { -fx-pie-color: pink; }
