Creating RadChart Programmatically - more complex example
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:
Explore the RadHtmlChart documentation and online demos to determine how it fits your development needs.
The figure above shows a more complex chart than the minimal example of programmatically created RadChart. This example demonstrates how to:
-
Create the chart, define the chart title and the title's appearance.
-
Define two different chart series, how to hide the series labels and tailor the series appearance.
-
Add multiple chart series items with data.
-
How to display point marks to highlight the data points.
-
Fill the plot area background with a gradient color.
-
Set axis line and label appearance.
