[Matplotlib-users] xkcd

Hello. I've only seen one way to use the xkcd feature. This uses a with statement. Is there another way to use the xkcd feature so as to easily switch between exact plot and trembling one ? Christophe BAL -- Meet PCI DSS

Re: [Matplotlib-users] xkcd

That's what the `with` statement allows you do. Say you have a function that does some plotting and returns a figure -- call it my_plot_func. You can do: fig1 = my_plot_func() fig1.savefig('normal1.png') with plt.xkcd(): fig2 = mu_plot_func() fig2.savefig('xkcd.png') fig2 = my_plot_fun

Re: [Matplotlib-users] xkcd

Also note, you can just call plt.xkcd() and it will turn on the setting globally for that session. On 4 October 2014 00:11, Paul Hobson wrote: > That's what the `with` statement allows you do. > > Say you have a function that does some plotting and returns a figure -- > call it my_plot_func. > >

Re: [Matplotlib-users] XKCD style graphs?

Nice challenge Fernando! Damon, I love the solution! I do wonder whether we could do some quirky transform on the lines to achieve a similar result, rather than manipulating the data before plotting it. The benefit is that everything should then get randomly Xkcd-ed automatically - maybe I will sa

Re: [Matplotlib-users] XKCD style graphs?

Yes -- this would be a great application for the path filtering infrastructure that matplotlib has. Mike On 10/04/2012 08:29 AM, Phil Elson wrote: > Nice challenge Fernando! > > Damon, I love the solution! I do wonder whether we could do some > quirky transform on the lines to achieve a similar

Re: [Matplotlib-users] XKCD style graphs?

This is just too cool of an idea to pass up -- I'm going to see if I can put together a PR that does this using the C++ path filtering stuff so it would be available everywhere. Mike On 10/04/2012 10:11 AM, Michael Droettboom wrote: > Yes -- this would be a great application for the path filter

Re: [Matplotlib-users] XKCD style graphs?

Here is my take on it as an IPython notebook, based on Damon's code: http://nbviewer.ipython.org/3835181/ I took the engineering approach and filtered the random function instead of doing some fft/ifft magic. Also, X and Y of the functions are affected now, giving them a more "natural" look in t

Re: [Matplotlib-users] XKCD style graphs?

Sweet! That should *defiintely* go into the mpl gallery, and honestly I'd love for it to be cleaned up enough to be usable to style generically any plot, much like the mathematica code I linked to earlier does. It would be a beautiful demonstration of matplotlib's capabilities, and furthermore, I

I've put up a PR adding this "sketchy" line drawing as a path filter. This makes it work with almost anything that matplotlib draws. https://github.com/matplotlib/matplotlib/pull/1329 Mike On 10/04/2012 06:06 PM, Fernando Perez wrote: > Sweet! That should *defiintely* go into the mpl gallery,
