Question

I am using the .NET datavisualization library to create some charts. The data is all time series based (ie, the x-axis is dates).

I know that I can use custom date and time format strings to format the x-axis labels (formatting from http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx), via the

AxisX.LabelStyle.Format = "yyyy"

command.

But what if I wanted to format the labels via a custom function that isn’t provided in the .NET library?

To be more specific, is it possible to format the x-axis labels using the Quarter of the date? In other words:

• Jan-Mar: Q1
• Apr-Jun: Q2
• Jul-Sep: Q3
• Oct-Dec: Q4

Thanks in advance!

Answer 1

Create your own function and return custom labels and assign them to data point individually

Eg:-

string lblText = CustomLabelFunction(Chart1.Series["Default"].Points[0]);
Chart1.Series["Default"].Points[0].AxisLabel = lblText;
