Re: [julia-users] Plots with scale bars

2016-08-10 Thread Tom Breloff 
Sure. You could maybe make a recipe, or just make a function that does
this. You'll probably want to make use of 'axis_limits' to get the data
range. Like this:

amin, amax = axis_limits(plt[1][:yaxis])

Here 'plt[1]' returns the first Subplot.

 Hello,

 Is there a simple way in Julia to add scale bars with labels to plots
 and to hide the x-y axes as well? The way to do in MATLAB involves a lot of
 manual tweaking as described here

 I'm hoping to find a more elegant way in Julia!

 Thanks,

Yes likely this could be done easily in a recipe if it's something you'd
want to do repeatedly.

Hi Tom,
It'd be cool if you can add a couple of examples, yes!
I'm not familiar with plot recipes yet, but do you think that such a scenario 
can be handled 'neatly' in a recipe while hiding all manual tweaking from the 
end user?
Thanks,Islam

There's a bunchof ways to do this with Plots. Draw the lines and add 
annotations or add an inset subplot with labels? I'm not at a computer... maybe 
I'll throw together an example later.
