If I am not wrong in multiplot.cs, size of each subplots is found simply dividing in to the subplot number in the rows and columns respectively.
Is it possible to add a feature to set the subplot size? For example, multiplot of size 800x600 includes two subplots of size:
subplots[0] is 600x400 pixels
subplots[1] is 200x400 pixels

Thanks.
