Re: Perpendicular lines do not appear perpendicular

Hi:

I used Jens idea, PlotRangePadding->[ ]. I experimented with the values and used:

ContourPlot[{2*x + 4*y - 6 == 0, 
-4*x + 2*y - 6 == 0}, {x, -4,4}, {y, -4, 4}, AspectRatio -> 1, PlotRangePadding -> {2.4, 1}].

This did it on my screen. The lines look perpendicular now.

Thanks to Jens and the rest of you for you suggestions.


Regards,

Bill
