Can the plot be scaled to show fine detail?

[pbowyer]

I have an issue with making the plot from a mprof run legible. This is how mine looks:

I'd like to be able to stretch/zoom the plot - make it much larger, so the function markers don't overlap.

I have tried changing matplotlib's savefig.dpi and figure.figsize values, and both result in the graph being scaled, rather than the canvas being larger and the line/function markers becoming thinner and separated, and the text smaller.

I tried a really wide figure using these settings in my matplotlibrc:

figure.figsize   : 200, 10    # figure size in inches
savefig.dpi      : 100

but it still plotted at 1400x600.

Do you know a way to make this possible?

Hi!

The code that creates the figure is here:

Right now the figsize is hard-coded but it would totally make sense to be able to set it via a command line option. Would that solve your problem?

[pbowyer]

I gave it a test by doubling the width on Line 454 - unfortunately it stretches the markers:

I see. What you would like is to have the legend outside the plot, right?

[fabianp]

I pushed a fix (fdab5be) that moves the legend out. I see things like this, tell me if that fixes it for you.

Not quite :) I'd like to be able to make the graph much bigger, so that all the function bracketing between 150-250 seconds on the graph don't overlap, and I can make out what's going on. I don't mind if the graph is 10000px wide to do this.

Currently if I change the graph size, it scales everything: line thickness, size of function bracket, size of text. I'd like the canvas size to be independent of these features, so I can "zoom in" on the PNG and see what's going on.

I see. Unfortunately my matplotlib knowledge is limited ... do you have an idea of what matplotlib code could give you what you are looking for?

[pbowyer]

No, my knowledge is limited too - I will try and find out.

[fabianp]

Cool, thanks. If you find a solution, please tell me :-)

@pbowyer: what you want is change the height_ratio here: https://github.com/fabianp/memory_profiler/blob/master/mprof#L258

Brackets are drawn as lines and they scale like the axis instead of having a constant size. There must be a way of doing the latter but I haven't spent enough time to find it. A stop gap would be to pass the aspect ratio as a parameter to mprof.

Hope this help...

[pgervais]

Ahem. height_ratio determines the height of the bracket relative to the vertical axis. But my point this holds.

Unsure whether this can be closed?

I assume #105 addressed this, so I'm closing.
