Hello,

When my chart, which supports dragging, is displayed using a linear scale, I can bound the ranges to (0, max_value) for both axes. However, when I switch the vertical axis to a logarithmic scale, I can "drag down" because the difference between vertical coordinates becomes infinitesimal and the 0 point seems to be placed infinitely "below", which is undesirable for me: I want to apply the same visual/movement restrictive behavior on the logarithmic scale as well. I have seen the same behavior in a standard QCustomPlot example (plot-example, setupLogarithmicDemo) when its logarithmic scale is enabled (but it does not bound).
Any comment would be greatly appreciated!
