Custom ChartPalette with more than 8 colors

[Raga]

Hi, 

To create custom ChartPalettes, you suggest in the doc that we clone an existing default ChartPalette and change the colors from there.

However, the existing default ChartPalettes only have 8 colors. I need to create a palette for my pie chart that has 20 colors. How can I accomplish this?

Thanks!

Hi Raga,

Thanks for the question.
Each palette contains multiple palette entry collections where each collection has a palette family. The family can be HorizontalAxis, VerticalAxis, Bar, Line etc. Each of these collections contains palette entries for the for the difference series or data points.
For example, the palette entry collection with a "Bar" family contains 8 palette entries which means 8 different bar series will have their own colors. To add more colors simply add more PaletteEntry objects to the collection.
For example:

ChartPalette palette = chart.getPalette().clone();
PaletteEntryCollection collection = palette.entriesForFamily(ChartPalette.BAR_FAMILY);
collection.add(new PaletteEntry(Color.GREEN, Color.RED));
// Add more entries here
chart.setPalette(palette);

Please write again if you need further assistance.

Regards,
Victor
