If the plot needs to be a specific size, it would be best to use the Set Plot Size dialog to set the plot to the desired size. If that would make editing the plot too difficult, work in a multiple of the final size (for example, twice as large as the final size). This will help prevent problems that could occur when resizing plots in another program.
