The margin for Fit Layer to Page is more accurate in graph.
Added LabTalk commands to specify each margin separately.
-ml value // for left margin
-mt value // for top margin
-mr value // for right margin
-mb value // for bottom margin
All the margin values can be negative, if necessary. For example, using the following will make the graph look tighter to also accommodate for text object rectangles of the axis titles being too large.
page -FLS -u -c 3 -ml -0.005 -mt 0.001 -mb -0.005 -mr 0.001
