How to Add Axis Labels Programmatically

Updated on Jul 8, 2026

RadChart has been deprecated since Q3 2014 and is marked as obsolete as of the 2026 Q2 SP1 (v2026.2.708) release. This is the last release that includes the RadChart component — its source code will be removed from the assembly in the next release. We strongly recommend using RadHtmlChart, Telerik's modern client-side charting component. To transition from RadChart to RadHtmlChart, refer to the following migration articles:

• Migrating Series
• Migrating Axes
• Migrating Date Axes
• Migrating Databinding
• Features parity

Explore the RadHtmlChart documentation and online demos to determine how it fits your development needs.

To add labels along an Axis programmatically:

• Set AutoScale to false.

• Add a range of items to the axis.

• Populate the Items.

  

C#

radChart.PlotArea.XAxis.AutoScale = false;
radChart.PlotArea.XAxis.AddRange(1, 7, 1); 
radChart.PlotArea.XAxis[0].TextBlock.Text = "Mon";
radChart.PlotArea.XAxis[1].TextBlock.Text = "Tue";
radChart.PlotArea.XAxis[2].TextBlock.Text = "Wed";
radChart.PlotArea.XAxis[3].TextBlock.Text = "Thu";
radChart.PlotArea.XAxis[4].TextBlock.Text = "Fri";
radChart.PlotArea.XAxis[5].TextBlock.Text = "Sat";
radChart.PlotArea.XAxis[6].TextBlock.Text = "Sun";

VB

radChart.PlotArea.XAxis.AutoScale = False
radChart.PlotArea.XAxis.AddRange(1, 7, 1)
radChart.PlotArea.XAxis(0).TextBlock.Text = "Mon"
radChart.PlotArea.XAxis(1).TextBlock.Text = "Tue"
radChart.PlotArea.XAxis(2).TextBlock.Text = "Wed"
radChart.PlotArea.XAxis(3).TextBlock.Text = "Thu"
radChart.PlotArea.XAxis(4).TextBlock.Text = "Fri"
radChart.PlotArea.XAxis(5).TextBlock.Text = "Sat"
radChart.PlotArea.XAxis(6).TextBlock.Text = "Sun"
