How to use a chart predefined color palette based on report parameter?
You need to create a custom code parameter that is later checked by code in order to modify the currently applied style sheet.
From the Chart Properties – Code tab, you can create a custom code parameter:
The following code applies a style sheet to the chart based on the palette specified as parameter:
[C#]
using System;
using System.Drawing;
using Nevron.GraphicsCore;
using Nevron.Chart;
using Nevron.ReportingServices;
namespace MyNamespace
{
// <summary>
// Sample class
// </summary>
public class MyClass
{
// <summary>
// Main entry point
// </summary>
// <param name="context"></param>
public static void RSMain(NRSChartCodeContext context)
{
int palette = context.GetInt32Parameter("colorPalette");
NChartPalette chartPalette = new NChartPalette((ChartPredefinedPalette)palette);
NStyleSheet sheet = NStyleSheet.CreateFromPalette(chartPalette, true);
sheet.Apply(context.Document);
}
}
}
Following is a list of the available palettes and their values:
// <summary>
// Enumerates the predefined palettes
// </summary>
public enum ChartPredefinedPalette
{
/// <summary>
/// Nevron
/// </summary>
Nevron = 0,
/// <summary>
/// Winter
/// </summary>
Winter = 1,
/// <summary>
