Two y-axis on the left side of the figure
matplotlib
Solution
Whats shown in red is the default `twinx()` behavior. The extra modification in the example applies to whats shown in green.
You can modify both new axes similar as the `green` one, but select the `left` spine and apply a negative offset. So add/change the example with:
par1.spines["left"].set_position(("axes", -0.4)) # red one
par2.spines["left"].set_position(("axes", -0.2)) # green one
make_patch_spines_invisible(par1)
make_patch_spines_invisible(par2)
par1.spines["left"].set_visible(True)
par1.yaxis.set_label_position('left')
par1.yaxis.set_ticks_position('left')
par2.spines["left"].set_visible(True)
par2.yaxis.set_label_position('left')
par2.yaxis.set_ticks_position('left')
The `zorder` from lines is only taken into account within the axes (or so it appears?), since you have separate axes on top of each other, you should modify the `zorder` of the axes:
host.set_zorder(1)
par1.set_zorder(2)
par2.set_zorder(3)
Note that the `host` has a white background, placing it on top will hide the other lines unless you set the background to be transparent.
Problem
I want to plot curves with different y-axis that share the same x-axis. I have used the `twinx` function before, but it plot them on different side of the figure. Is there a way to plot both of them on the left hand side. I am looking for something like the following but with both the axis on the same side. The code for the above example is here. On a different not, can one plot the curves in some particular order, as z-order do not work for `twinx`
