If y(x) <0 for all x, ListPlot plots negative y values. How do i keep y(x) below the x axis, re-labeling the y axis (e.g., -20 -> 20)?
Thanks Ahmed. It worked!
What about that
Plot[Tan[x], {x, 0, 10}, PlotRange -> {-10, 0}, Ticks -> {{2, 4, 6, 8}, {{-2, 2}, {-4, 4}, {-6, 6}}}]
That might do it. I'll try. Thanks
Thanks Ahmed. However, the example you provided simply cuts off the negative values. That isn't what I need though. If you look at my plot above, I only want to change the appearance of the negative y values, maintaining the curve as is: literally only change -5 to 5, -10 to 10, -15 to 15, -20 to 20.
Hi Alan
This option answers you question https://reference.wolfram.com/language/ref/PlotRange.html Here is an example, try to evaluate both:
Plot[Tan[x], {x, 0, 10}, PlotRange ->{-10,10}] Plot[Tan[x], {x, 0, 10}, PlotRange ->{0,5}]
