Qwt Log Scaling Problem

[BettaUseYoNikes]

I have an option on my plot where the user can independently switch the scales of the x and y axis to Log Scaling. The problem I am observing is with curves that are relatively linear except for a slight increase at the end. I will attach a picture but basically the scale on the y-axis seems to get crowded with way more than the allowable amount of major and minor ticks. I have tried auto-scaling and manually scaling the axis based on the max and min of the curve with the same results.
