+ - [QTBUG-75500] Prevent zoom-out beyond infinite linear max double values
+ When zooming out domains that include log axes, prevent zoom-out when
+ the new zoom level would result in a max value that is above the upper
+ range of double (represented as inf). Additionally, prevent zoom-out
+ when the log value exceeds the number of pixels in the log axis
+ dimension. Major gridlines are created at each integral log value, and
+ it does not make sense to zoom out beyond such point.
+ The bug was: Stack overflow on high zoom out of QChart with a
+ logarithmic axis
