Example: I have data points for X,Y and Z from -5 to 5 with steps to 1. A fourth column represents the value for the coordinates. It is used to color / shape / size the shown data points. Now comes the point: As long as auto ranging is active and all axes (X,Y,Z) are shown in full range, everything is fine. Now one can change the scaling of the X and Y axis to visualize just one plane, eg. range X or Y from -1 to -1. This works, only one plane is shown, all other data points are off. However, if one tries this with the Z axis, the result gets weird. First, setting the Z axis to a specific value does not work - one gets always a range. In my case setting Z lower = Z upper = -1 results in Z upper = 0 and Z lower = -1. Second, not only 1 (or 2 due to the Z range) but more planes are shown. This confuses (not only optically)... My current workaround for this is a script extracting the data for a specific plane i want to be shown. However, it could be easier without the 'bug' described...
