How to show X-axis?

[pauljurczak]

My plots don't show X-axis, e.g.:

All the examples I've seen have no X-axis either. How can I show it?

I see the x-axis there. Its label is "Time [s]" and the ticks are [0, 5, 10, 15, 20, 25, 30].

What I meant is an X-axis in geometrical sense, see green line below:

Oh... Then you'll need to find an axis function to customize that: https://github.com/alandefreitas/matplotplusplus/blob/master/source/matplot/core/axis_type.h

I don't know if there's one, maybe

matplotplusplus/source/matplot/core/axis_type.h

Line 89 in 289f757

class axis_type &zero_axis(bool zero_axis);

as in https://github.com/search?q=repo%3Aalandefreitas%2Fmatplotplusplus%20zero_axis&type=code

At worst, you can always draw a line over the coordinate and reset the axis limits.

you can always draw a line

That's a good option. I found that plt::grid(plt::on) does an adequate job, too.
