Hi Tom,
Thanks for your input. This solution seems similar to the one proposed on
matlabcentral. It's fine for now, but it'd be great if switching between a
plot with x-y axes to a plot with only scale bars can be done neatly using
a single switch or function, while hiding all the details from the end
user. For example, figuring out the correct parameters for the text
annotation is a function of current plot scale (min/max), the text size of
the displayed text, ... etc. Ideally, the end user shouldn't need to fiddle
with all these details, and the scale bars functionality should `just work'
as the x-y axes functionality does!
Thanks,
Islam
PS: the first plot command gives me `ERROR: Unknown key: axis`. But I
assume that is because I'm currently on Julia v0.4.6 with Plots v0.8.2.
