thanks Bruno for your answer not exactly in your example, only the grid in inclinated in my need, also th axis would be inclinated something like this where B is (0,1) and C is (1,0) and A is (0,0) Vincent > Le 21 oct. 2020 à 02:46, Bruno Beltran <brunobeltran0(a)gmail.com <mailto:brunobeltran0@gmail.com>> a écrit : > > Hi Vincent, > > Is this the kind of thing you are looking for? > > https://matplotlib.org/gallery/api/skewt.html <https://matplotlib.org/gallery/api/skewt.html> > > Best, > > Bruno > > On Tue, Oct 20, 2020 at 2:15 PM Vincent Douce Mathoscope <mathoscope(a)netcourrier.com <mailto:mathoscope@netcourrier.com>> wrote: > hi i would like to create some graphics with the y-axis inclinated in any angle with the xaxis, for example 45°, 55° as i need it > i dont find here : > http://python-simple.com/python-matplotlib/configuration-axes.php <http://python-simple.com/python-matplotlib/configuration-axes.php> > https://matplotlib.org/3.1.1/api/axes_api.html <https://matplotlib.org/3.1.1/api/axes_api.html> > anything in this direction > any tipps ? > Vincent > > _______________________________________________ > Matplotlib-users mailing list > Matplotlib-users(a)python.org <mailto:Matplotlib-users@python.org> > https://mail.python.org/mailman/listinfo/matplotlib-users <https://mail.python.org/mailman/listinfo/matplotlib-users> ---- https://lemathoscope.com/ <https://lemathoscope.com/> cours de maths postbac par visio ---- https://lemathoscope.com/ cours de maths postbac par visio

hi i would like to create some graphics with the y-axis inclinated in any angle with the xaxis, for example 45°, 55° as i need it i dont find here : http://python-simple.com/python-matplotlib/configuration-axes.php <http://python-simple.com/python-matplotlib/configuration-axes.php> https://matplotlib.org/3.1.1/api/axes_api.html <https://matplotlib.org/3.1.1/api/axes_api.html> anything in this direction any tipps ?

controlling ticks
by Neal Becker Oct. 15, 2020

Oct. 15, 2020

I am plotting with semilogy. I am getting the tick labels as powers of 10, which is what I want. However, because the range of data is large, the tick labels are every 2 powers of 10, [10^-1, 10^-3 ...] What's the easiest way to change so that the tick labels are for each integer power of 10, [10^-1, 10^-2 ...]? -- *Those who don't understand recursion are doomed to repeat it*

If the output size of .pdf is your concern, I suggest you export your figure with matplotlib in .eps, and then use the command line tool « epstopdf » shipped with any LaTeX distribution. The .pdf backend of matplotlib is far from being optimized. I always observe a factor of size decrease between 10 and 100 (!) in the output .pdf after running epstopdf, instead of saving directly in .pdf.

large pdf files
by fiolj Oct. 5, 2020

Oct. 5, 2020

Hi, checking on sizes of pdf files I noticed that in my system currently pdf output are at least 370k when similar plots previously were about 20k. I tested with an old figure (I do not matplotlib version but was created about May 2019) and the figure was 15409 bytes while the same figure with matplotlib version 3.2.2 has a size of 429110 bytes. I checked and this happens even plotting a few (ten) points with line, everything using default values. My user configuration file has not been modified but my system may have changed. I've found similar reports but regarding much older versions. Any ideas? Regards, Juan

Simplifying plots (reducing data points)?
by Neal Becker Oct. 2, 2020

Oct. 2, 2020

I produced a line plot as: ax.plot (x, y, '.') and saved as pdf. Both x and y were large vectors, resulting in a large pdf, and when incorporated into a LaTeX document, the resulting pdf takes a long time to open. Other than my manually decimating the vectors: ax.plot (x[::100], y[::100], '.') Is there some way within mpl to simplify plots? Or perhaps post-processing the pdf? Thanks, Neal -- *Those who don't understand recursion are doomed to repeat it*
