Arguments

mSetObj	Input name of the created mSet Object
imgName	Input a name for the plot
format	Select the image format, "png", or "pdf".
dpi	Input the dpi. If the image format is "pdf", users need not define the dpi. For "png" images, the default dpi is 72. It is suggested that for high-resolution images, select a dpi of 300.
