I wish to add this type of graph in my datagridviewcontrol :-

Here the graph is to plotted for 12 months and I can either input percentages or comparative values in pixels for the 12 months….Please also tell how to color the graphs
Any ideas for doing this will be highly appreciated
Edit—-Thanks for all the answers I learned a lot but still couldn’t get around the problem…

I need to display a lot of rows in my datagridview with around 15 columns….So its very odd to directly add the rows but add a different columns for graph each time I add a row…couldn’t think of any other way of accomplishing this….moreover I don’t want to save the images which I found I have to if i add the images directly into the grid view…..

Is there any third party tool there which may help me to get custom datagridview with charts
Thank You .
