Note: I'm looking at the Picker examples now and one problem I see is that I'm not asking the user to click on data points, but anywhere on the axes.

For my application which is a simple sound file editor written with matplotlib and PyQt4, I want to detect left and right clicks on the canvas. I need to know the data coordinates of the click (i.e., not where on the screen the click occurred, but what data point as defined by the axes it represents). How do I do this? Mike |

In fact I guess it could also be related with the display card of the PC I am using. I find I have different quality on my two different laptops (one with fedora and one with ubuntu). But it's getting too complicated ... I don't want to got this far and so let us forget about this.

Yes, in fact I set dpi as 1000, which is already very high. In fact I have another question, will there be any difference if I use the save button on the interactive plotting toolbar and use the command line figure.savefig('xx.png',dpi=1000)?

Hi all, Thank you all for your kind response. I am sorry, but none of these solutions significantly improved the visual quality on microsoft powerpiont 2007. Thought I didn't try eps. So probably l have to go with the current quality. here is a best case I have now: https://www.dropbox.com/s/0uhjogalz92hssm/different_figure_example.pptx You can still see the "a bit blur" everywhere (currently with jpg being inserted directly). I didn't have better quality than this one by trying the method as suggested by you. Let me know if I am raising too much high demand for this.

Another alternative, if a vector graphics format doesn't work, is to make your png figure large. Then when you shrink it down to fit in your slide, it should still have good resolution.

Mac is kind of my blind spot, thanks for pointing out that EPS is a viable format there. Windows does not handle the PS part of EPS for screen display. You will only see a preview image, and only if it was embedded into the EPS. Printing is be fine though, if you have a PS printer.

While SVG isn't supported, EPS is... sort of. Be very careful going between windows and mac versions of Powerpoint. While they both support EPS, they seem to do it differently and I have had to make emergency fixes to presentations while at conferences because they were using Windows and I only had access to Linux and Macs at home.

No Powerpoint version I know supports SVG (or any vector graphics format useful in this case) and Matplotlib does not export WMF graphics anymore. So the easiest way is to use PNGs, if you can live with raster graphics. Alternatively, if you need vector graphics, you can export the Matplotlib plot as SVG and convert it to WMF or EMF using Inkscape. This can be done in the command line like this: "c:\Program Files\Inkscape-0.48\inkscape.exe" --without-gui --export-emf="output.emf" "input.svg" Juergen Am 21.04.2014 13:06, schrieb Neal Becker: > Make sure to save into a vector graphic format so it can be resized.

Sorry hit send by accident? What parameters are you passing to `savefig`?

It's hidden away, but a script to do this type of thing exists. For a long time it was effectively our testing mechanism--run all the examples and scan the results to see if they looked right.

Note that I did get FuncAnimation to work perfectly well except I have little control over the timing so I had a hard time synchronizing it with the sound. The FuncAnimation example I looked at wasn't very helpful if the question is how to blit or other details, because that's all going on behind the scenes. I will study the Stack Overflow Q&A and see if there is something I can directly use. Mike |

Hi Mike, Have you tried blitting? That prevents the draw from redrawing everything on the plot, allowing it to only redraw the single line that's moving, which should help any issues with speed. See some of the examples<http://matplotlib.org/examples/animation/index.html>with FuncAnimation and also a Q&A using the draw method here<https://stackoverflow.com/questions/8955869/why-is-plotting-with-matplotlib-so-slow/8956211#8956211>, which might work more smoothly with QTimer.

Dear all, Did anyone try to make plots using matplotlib, and then put the figure in the powerpoint for presentation? Currently I am using the ipython notebook --pylab mode to make the plots, and then save them to *jpg format. But when I put it into the powerpoint, it does not look nice as I see on the screen (a little bit blurred). You can really not notice it if you don't examine carefully. But I really want to make high quality slides. So does anyone have the same problem? could it be related with the figure format or backend (GTKAgg) currently I am uisng? thanks a lot in advance.

I'm creating a simple little sound file editor, which includes the ability to play a sound file as a vertical line (a "cursor") moves across the plot of the waveform in sync with the sound. So the trick is, how to create this moving line. First I tried FuncAnimation, but I had problems with the synchronization with the sound. I'm guessing that the animation capabilities of matplotlib weren't really designed to be synchronized with outside activities. So then I tried using QTimer's and modifying the Line2D instance that is the vertical bar. This didn't work unless I called draw() on the figure canvas every time I modified the Line2D, which caused slowdown (probably because my audio data consists of 1000's of points). So is there a way to animate a vertical line moving across the plot with good control over exact timing, in the presence of other plots with thousands of points? Mike |

It > would be nice to have a concise listing of the methods of Axes. I agree. What is needed is a listing of methods by category instead of all together as a single alphabetical list. In the meantime, you might find browsing the User Guide to be of some help. Also, the "Quick Search" box can help.

This will clear the figure: plt.clf() Is this what you're looking for, or just to pop one plot form the stack?

Sorry for what is a beginnerish question but I'm having a hard time using the docs. I want to remove a previous plot from an axes. How do I do this? Incidentally, it makes the docs hard to use that there are so many methods on Axes which are spread a great distance over the page. It would be nice to have a concise listing of the methods of Axes. Note that I'm not using pyplot, but I think the term for what I'm doing is using the API. I'm subclassing FigureCanvas in PyQt, creating a Figure, and creating an axes using Figure.add_subplot().

matplotlib is impressive in its capabilities, I didn't realize how much so until I download from the git, and made a little script to run all of the examples. I'm way too much of a newbie here to check anything in, but I thought someone may find this trinket useful. As written, it should be in the 'matplotlib/examples' directory named 'runAll.py', if someone is so inclined to check it in.

Gang: Are there any webagg examples you could point me to? With webagg configured as the backend in my matplotlibrc and the following code, my browser opens after the call to show() with a webpage “MPL | WebAgg current figures” and a link to “Figure 1”, but I don’t get any plot, before or after clicking the link … >>> import matplotlib.pyplot as pyplot >>> import numpy >>> pyplot.plot(numpy.random.random(100)) [<matplotlib.lines.Line2D object at 0x103398f90>] >>> pyplot.show() Press Ctrl+C to stop server Many thanks, Tim Timothy M.
