The Scaling Factor is an option within ReportMiner located in the "Report Options". You would use the option when the spacing of your PDF is not lining up your data perfectly.
By default, the scaling factor is always set to 0. When you are experiencing this spacing issue, we recommend changing this value to 3.9. Anything between 3 and 4 usually solves the issue (You can play with this number to what works best for you).
Click on the "Edit Report Options" button (This looks like a screw driver and wrench)
The "Report Options" window will pop up. This is where you will adjust the scaling factor option.
Locate the "Scaling Factor" option box and change the value. Then select "OK"
