  • 0

I’m using the Microsoft Chart Controls, and displays data with dates along the X axis and want to have a grid line with a different color on some dates.

Let’s say I display data for one week with 7 values along the X-axis:

05.04.09 06.04.09 07.04.09 08.04.09 09.04.09 10.04.09 11.04.09

In addition I have a collection of DateTimes and names for some events, where one is on 07.04.09 and another is on 10.04.09. I then want to have a vertical grid line drawn on each of these dates and a label added with the event name.

I just can’t figure out how the heck I can achieve this. Any help appreciated.

    I solved this by subscribing to the PostPaint event. In the event handler I simply draw the lines myself and add the labels on top of these vertical lines.
