Change each Bar color in RadCartesianChart

[Alberto]

Hi,

I am creating a RadCartesianChart and adding bar series this way:

chartSafety.VerticalAxis = new LinearAxis();
            chartSafety.HorizontalAxis = new CategoricalAxis();

            DataTable dtSafety = new DataTable("DATA");

            dtSafety.Columns.Add(new DataColumn("Name", typeof(string)));
            dtSafety.Columns.Add(new DataColumn("ValueBar", typeof(double)));

            dtSafety.Rows.Add(new object[] { "Value1", 70 });
            dtSafety.Rows.Add(new object[] { "Value2", 15 });
            dtSafety.Rows.Add(new object[] { "Value3", 34 });
            dtSafety.Rows.Add(new object[] { "Value4", 87 });
            dtSafety.Rows.Add(new object[] { "Value5", 45 });
            dtSafety.Rows.Add(new object[] { "Value6", 22 });
            dtSafety.Rows.Add(new object[] { "Value7", 33 });
            dtSafety.Rows.Add(new object[] { "Value8", 65 });
            dtSafety.Rows.Add(new object[] { "Value9", 19 });
            dtSafety.Rows.Add(new object[] { "Value10", 41 });


            BarSeries barSer = new BarSeries();

foreach (DataRow drSafety in dtSafety.Rows)
            {
                barSer.DataPoints.Add(new CategoricalDataPoint() { Category = drSafety["Name"], Label = string.Format("{0:N}", drSafety["ValueBar"]), Value = double.Parse(drSafety["ValueBar"].ToString()) });


            }

            chartSafety.Series.Clear();
            chartSafety.Series.Add(barSer);

Is there a way to change the color for each bar in the series while I am creating each data point?

Regards,

Alberto

Hi Alberto,

 There are various ways to colorize bar series as you'll find in our documentation here. In brief you might either create your own palette of brushes or create custom styles for the individual bar items depending on your custom logic (achievable via Custom Item Style delegate).

The link is referring to RadChart rather than RadCartesianChart. So it is not working. I am looking an answer as well.

Hello Hui,

This is the RadChart forum. You can find more about this topic for RadChartView in the Binding the Color of Series Items article.
