Hide blank series labels from legend in check box chart

Hey there,

For the last few days I’ve been working on putting together an XY scatter plot chart that populates based on what check boxes I have checked. I’ve been able to accomplish this in little time but have been stuck trying to remove the blank series animation lines that remain in the legend when a check box is not clicked. I have about 40 different data curves and only need to compare 5 or 6 at a time. I would like the legend to shrink and only show what’s checked with no gaps/ blank lines remaining. I’ve played with a few different VBA scripts I found online but no success.

Any help would greatly be appreciated!

The two photos were taken at different times -hence the difference in clicked fields
