When several charts are placed over each other (vertically), if they have a variable number of lines in the Labels, they get misaligned - the plot area has different sizes, positions, values on the X axis, which hinders reading the data. IMHO, it is ugly, too. I have added an image to illustrate the issue.
Currently, I cycle all the charts, count the number of CrLf in their labels, and add CrLfs to the shorter lines. But the ability to set the size of all the margins will make life easier.
