Dundas -Make custom data points and marker

My client Kathy loves reporting and she can ask anything on report...well one day she asked me to change the data point to a line (big line..) and to be my surprise there is not automatic marker style in SSRS to make this happen...but thanks to her that she has given me license to Use dundas...

well after trying it hard ..i found the way and it brought a smile on her face ...
To implement this
1)Create a custom line image in mspaint and save this as a file in the folder where your report solution is located
2)Click on the series for which you want custom marker style ..select Data point and use marker image to locate the file which you have created
3)Use marker style none in data point --Marker style section...

and you are done with custom marker
