These values are generating correctly when I first generate a log of the graph and then generate an inverse for the log graph but when I directly generate inverse log functions in the dropdown, these values are not correct.
Go to the Selection Info panel and verify that all tracks have the expected y coord corresponding to the original value of 16:
Mac
inverse of log (16, base=3): 0.3962406
inverse of log (16, base=2): 0.25
inverse of log (16, base=10): 0.830482
inverse of natural log of 16: 0.3606738
When I am performing the inverse operation, the graph was shown empty, and then I adjusted the Max Value which showed the graph clearly.
