When plotting Makie automatically set axis limits. I would like to keep the automatically generated upper limit while setting the lower one to zero. How could I do that?
At first I wanted to get the current limits and reset them, but ax.limits give me (nothing, nothing).
I would have to add that scenario specifically, I guess I could go with ((nothing, lim), nothing) for setting the upper x limit, for example. What is the scenario in which you want to do this, so I understand it better. Are you adding plots but don’t want zero to shift? Also, ax.finallimits is what contains the actual current limits
I am plotting errors (always positive) for different methods. If the errors are all huge but one is like 1% smaller, having limits tight around the lines make it look like one method is much better than the other when really it is not. I want like the plot to start at 0 so that relative small difference or noise actually look small.
Using ax.finallimits I did the following
rect = ax.finallimits[]
topy = (rect.origin + rect.widths)[2]
ylims!(ax, -0.1*topy, topy)
which allows me to get what I want (okay I still need to move the legend)
It could be made nicer in the API but it works for me as it is 
Sorry to revive an old topic. But was there a better way to do this added to the API in the end?
Similar to what you would do in pyplot, with set_ylim(bottom=0), to set the lower limit to 0 but letting the upper limit to be inferred from the data.
ylims!(low = 1) or xlims(high = 5) for example
