How to Extend the Displayable Area for YAxis Data

RadChart has been deprecated since Q3 2014 and is no longer recommended for use, as it does not support modern browsers. 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.

"My data touches the upper boundary of the plot area but that makes the data harder to see. How do I extend the viewable area along the YAxis?"

Assign the YAxis AxisMode property. By default the ChartYAxisMode property value is Normal and the YAxis data fills the available space.

myChart.PlotArea.YAxis.AxisMode = ChartYAxisMode.Normal;

If you set the ChartYAxisMode to Extended, additional area is placed above the highest data point to make the chart easier to read.

myChart.PlotArea.YAxis.AxisMode = ChartYAxisMode.Extended;
