ColorGrid reset the StartColor & EndColor values

[vivek]

Dear Support,

In colorgrid we want to reset the StartColor and EndColor values for series values. For example if the series values are 1,2,3,4,5,6,7,8,9 and 10 then StartColor white will be assigned to value 1 and EndColor red will be assigned to 10 in color grid, but if I want to assign the start color value as 5 instead of 1 and end color value as 8 instead of 10 then how to achieve this.

Faster reply will be appreciated.

Thanks

Hello vivek,

If you want to assigned diferents colors in the colorgrid, you need to use a custom palette. I recomened that see this post, that explain exactly how do for creat a custom palette.

Hello vivek,


I think, you should assign a palette for each of the color grids. Please, try to assign the palettes, and check that solve your problem.

I hope that will helps.

Dear Sandra,

In that case I can't scale the color across the grid from min.(white) color value to max.(red). Moreover it will degrade the performance.

Hello vivek,

I have made an example, that you could use for solve your problem of ColorGrid using 2 palettes. Please check that next example solve your problem.

Code: Select all

 public Form1()
        {
            InitializeComponent();
            InitializeChart();
        }

        Steema.TeeChart.Styles.ColorGrid colorgrid1;

        private void InitializeChart()
        {
            tChart1.Aspect.View3D = false;
            colorgrid1 = new Steema.TeeChart.Styles.ColorGrid(tChart1.Chart);
            Random rnd = new Random();
            int count;
            count = 0;
            double[] xValues = new double[48];
            double[] yValues = new double[48];
            double[] zValues = new double[48];
            for (double x = 0; x < 6; ++x)
            {
                for (double y = 0; y < 8; ++y)
                {   
                    xValues[count] = x;
                    zValues[count] = y;
                    if (rnd.Next(100) <= 25)
                    {
                        yValues[count] = rnd.Next(100) - 25;

                    }
                    else
                    {
                        yValues[count] = rnd.Next(100);

                    }
                        ++count;
                }
            }
            colorgrid1.Add(xValues, yValues, zValues);
            colorgrid1.Marks.Visible = true;
            colorgrid1.Marks.Transparent = true;

            colorgrid1.UsePalette = true;
            colorgrid1.UseColorRange = false;
            colorgrid1.Palette.Clear();

                    colorgrid1.AddPalette(-15, Color.FromArgb(255,255,255));

                    colorgrid1.AddPalette(0,Color.FromArgb(255,220,220));

                    colorgrid1.AddPalette(10, Color.FromArgb(255,189,189));

                    colorgrid1.AddPalette(20, Color.FromArgb(255,179,179));

                    colorgrid1.AddPalette(30, Color.FromArgb(255, 149, 149));

                    colorgrid1.AddPalette(40, Color.FromArgb(255, 138, 138));

                    colorgrid1.AddPalette(60, Color.FromArgb(255, 0, 0));

                    colorgrid1.AddPalette(61, Color.FromArgb(0,0,255));

        }

        private void AddPallete_Click(object sender, EventArgs e)
        {

            colorgrid1.UsePalette = true;
            colorgrid1.UseColorRange = false;
            colorgrid1.Palette.Clear();

                    colorgrid1.AddPalette(-15, Color.FromArgb(255, 255, 255));

                    colorgrid1.AddPalette(0, Color.FromArgb(0, 0, 0));

                    colorgrid1.AddPalette(10, Color.FromArgb(255, 189, 189));

                    colorgrid1.AddPalette(20, Color.FromArgb(255, 179, 179));

                    colorgrid1.AddPalette(30, Color.FromArgb(255, 149, 149));

                    colorgrid1.AddPalette(40, Color.FromArgb(255, 138, 138));

                    colorgrid1.AddPalette(60, Color.FromArgb(255, 0, 0));

                    colorgrid1.AddPalette(61, Color.FromArgb(0, 0, 255));
               tChart1.Refresh();

        }
        private void button1_Click(object sender, EventArgs e)
        {
            tChart1.Series.Clear();
            InitializeChart();

        }

I hope will helps.
