Hi Mark,
I try everything, it doesn't work with X-axis on Grabber. Maybe i miss something here.
When i right click the size/scale -> there is only allow to change the Y-axis scale not the X-axis one.
And i think the grabber tool only work on Numeric data, not work on category data. if my graph both y & x-axis is numeric data with scatter plot, then i am able to scale both x & y-axis. Please correct me if i am wrong.
