Created attachment 53784 [details] Chart with and without orthonormal axis Hello, When I create a new XY-chart, there's not orthonormal axis : Workaround : If I want a orthonormal axis, I must use MAX and MIN function for a new data serie. Format new data series with invible line's style. Perhaps create a new entry in menu Format > Axis > Orthonormal ? Best regards
I can confirm this behaviour. It would be a good idea to create orthonormal axis. In mathematical lessons we need such a function - or it's too difficult to reproduce the difference between, for example, f(x)=x² and f(x)=5x² in different charts. The charts of the functions would both look the same for pupils.
