[Matplotlib-users] Animation of a scatter plot with a large number of points
Good afternoon. I have a list of 2 points with coordinates x,y and category in three lists. x_coordinate=[3000,3100,3234,.] x_coordinate=[15678,16768,14590,.] category=[1,3,5,] The categories values are between [1 and 10] I need to make a 2D animation of this in matplotlib, starting showing the first element and finalizing showing all elements in the graph, showing the color points cording to the category. I tried modifying the example of animatedScatter, but I can see that the number of points in the scatter plot is constant from the beginning. is there any way to make the program, for example show in the first time step one element one point in the second time step, two points, etc? and also one important thing is could cop with a big list of points with the minimum lag of time in the animation?

Re: [Matplotlib-users] Case stories of software including Matplotlib
Benjamin In my case, I'm in the process of "selling" Matplotlib at the interior of the company for that I work, and it will be a strong point if I could get references or recommendations from commercial software or institutions that had success using Matplotlib. In my point of view, the idea to add this to the webpage will be a very good first impression of the software. regards, German On Tue, Jul 27, 2010 at 3:05 PM, Benjamin Root wrote: > On Tue, Jul 27, 2010 at 6:01 AM, German Ocampo wrote: >> >> Good morning >> >> Do you know where I could get examples of case stories about >> commercial or open source software that has been developed using the >> Matplotlib library? >> >> Many Thanks >> >> German >> > > German, > > Interesting idea.

[Matplotlib-users] Zoom event assigned to a Push button in QT
Good afternoon I'm working in an application with a simple figure embbebed in a QT Dialog. I want to instead of use the navigation toolbar of matplotlib, have some Qt push buttons in the form, that allow to perform the Zoom and Pan. Is it possible to do it?

Re: [Matplotlib-users] Animation with an image in the backgroud
Benjamin Thanks for your advice. I Modified the example in the way that you say and now is working well. Basically I load the image before copy_from_bbox and also I take out the self.ax.clear() in the timerEvent. I'm including the program example with the animation of a dot following a circle path with lena.png in the background.

[Matplotlib-users] scatter plot with discrete colorbar
Hi I'm using the following code for insert a scatter plot in a figure in Qt. vmin=min(r_time[:]) vmax=max(r_time[:]) valores=np.arange(vmin,vmax+1) a1=self.ui.axes4.scatter(r_east,r_nort,vmin=vmin,vmax=vmax,c=r_time,edgecolors="none") b1=self.ui.fig2.colorbar(a1,values=valores,format="%.3f",spacing="uniform") The plot is ok and and the colors in the colorbar are ok, but for some reason the ticks are missing. I tried b1=self.ui.fig2.colorbar(a1,values=valores,ticks=valores,format="%.3f",spacing="uniform") but still the ticks doesn't appear. How can I get the ticks in the colorbar?

Re: [Matplotlib-users] Axes3D - size of the Z axe
Hello After search in google, I found a solution changing the initial point of view of the plot, using a function which control the angle and elevation of the initial view: ax.view_init(elevation, azimuth) and tried and works ax = Axes3D(fig) ax.view_init(64, -30) Question: Is it possible to include this function in the Axes3D documentation web page? or where I could find it in the webpage? http://matplotlib.sourceforge.net/mpl_toolkits/mplot3d/api.html?highlight=axes3d#module-mpl_toolkits.mplot3d.axes3d Thanks German On Fri, Oct 2, 2009 at 1:24 PM, German Ocampo wrote: > Hello everybody > > How can I control the size of the Z axis in a 3D plot using Axes3D in > matplotlib? > > regards > > german > -- Come build with us!
