Issue with suptitle
by Isaac Gerg May 6, 2016

May 6, 2016

Hi, I am currently writing a test suite by which you input your matplotlibrc file and it generates you a set of commonly used plots so you can examine the aesthetics of your config. I am having 2 issues, 1. How do I make SupTitle centered in matplotlibrc? 2. How do I make the points larger on the scatter plot? See attached pictures.[image: Inline image 2][image: Inline image 1] I'm happy to share the code if someone wants it. Isaac

Multi-colored Text
by Michael W. Lance March 29, 2016

March 29, 2016

Hello, I have become increasingly frustrated with something that should really be simple in MPL: I want to be able to easily modify the colors of each word (or even letter) of a title (or text) in a plot (inside or outside of the axes). On the MPL site, there is this: http://matplotlib.org/1.5.0/examples/text_labels_and_annotations/rainbow_te… But there are 2 problems with this approach: 1. It results in uneven spacing between words and 2. I cannot figure out how to apply a custom font style Here is some sample code: import matplotlib.pyplot as plt plt.rcdefaults() %matplotlib inline from matplotlib import transforms fig = plt.figure(figsize=(4,3), dpi=300) hfont = {'fontname':'Nexa_Light.otf'} def rainbow_text(x, y, strings, colors, ax=None, **kw): if ax is None: ax = plt.gca() t = ax.transData canvas = ax.figure.canvas #horizontal version for s, c in zip(strings, colors): text = ax.text(x, y,' '+s+' ', color=c, transform=t, **kw) text.draw(canvas.get_renderer()) ex = text.get_window_extent() t = transforms.offset_copy(text._transform, x=ex.width-5, units='dots') print(ex) plt.show() rainbow_text(0.2,1.05,"This is a long sentence. I hope it works out well.".split(), ['b','r','g','orange','g','b','black','orange','g','b'], size=12,**hfont) Confidentiality Notice: This e-mail, including any attachments is the property of Trinity Health and is intended for the sole use of the intended recipient(s).

traits lite?
by Chris Barker March 15, 2016

March 15, 2016

I recall conversations about using a lightweight version of traits to manage configuration, etc for MPL. Whatever became of that? Im interested because I could use lightweight traits-like sytem for another project -- wondering it it's been built already. my google-fu is totally failing me on this one. -CHB -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

GSoC 2016.
by Рудольф Лайко March 14, 2016

March 14, 2016

Hello! My name is Rudolph Layko. I am pursuing my bachelor`s degree in Applied Mathematics at National Research University - Higher School of Economics (Moscow, Russia). I would like to express my fascination by opportunity to contribute for matplotlib due to the fact that I am frequent user of this powerful library. Especially, I am really interested in solving of issues that I am personally was facing in process of using such as those concerning categorical axes and losing a connection with original data while plotting("Compound Artists"). Furthermore, It would be really great to interact with professional team on opensource project. According to this, I want to ask if there is anything that I can start to working on right away in order to get more acquainted with problems, or maybe you could provide me with some relevant information for the further work.I have a strong background in main data analysis libraries such as NumPy, Scipy, Pandas, SciKit. I hope this and some other technologies that I worked with will help me to tackle the issues. I am looking forward to hearing from you soon! Best regards, Rudolph Layko

Query regarding design of a new API (GSoC 2016)
by Yeshwanth Sai Charan March 12, 2016

March 12, 2016

Hi Developers, I'm Yeshwanth from IIITDM Jabalpur, India. I want to develop a new API for matplotlib which can automatically plot most of the visualizations required by data scientists. For example plots like the one shown in this stackoverflow issue ( http://stackoverflow.com/questions/14391959/heatmap-in-matplotlib-with-pcol…) can be developed with a single function using the new API. The API can deal with certain types of data as mentioned here https://github.com/numfocus/gsoc/blob/master/2016/ideas-list-matplotlib.md#… . Please let me know the things I've to consider before designing this API. regards, Yeshwanth

by Chris Barker March 11, 2016

March 11, 2016

Hi all, Anyone know what's up with wxMPL? It looks like Ken hasn't updated in soe time, and it doesn't work with recent MPLs: from matplotlib.axes import _process_plot_var_args ImportError: cannot import name _process_plot_var_args We had a discussion about this a good while back: https://sourceforge.net/p/matplotlib/mailman/message/29770257/ anything ever come of that??? -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Changing rcParams locally, on the fly
by Phyks March 9, 2016

March 9, 2016

Hi, Is there a way to change locally the rcParams, for a specific figure after it has been created? I know about the rcParams setting (for global settings) and the with statement construction, but this requires to be done before the figure was created, and I need to change the settings on an already existing figure (in particular color cycler).

GSoC 2016- Categorical axes
by sandeep bharti March 9, 2016

March 9, 2016

Hi, I am Sandeep Bharti and I am currently in 3rd year pursuing my undergraduate program in Computer Science. I am interested in the project for making a user friendly API to deal with different types of data. I have the required prerequisite for working on the project and I think I will be able to work on it perfectly. I want to discuss the idea and scope of the project so that I can start researching on it as soon as possible and also it will clear all the doubts regarding the project. I will be very thankful if you can provide me the IRC for the project so that I can contact the interested people to make it even better. I will look forward to hear from you on this. Many Thanks, Sandeep Bharti
