[Matplotlib-users] 3 questions about tick labels for large values
Folks,
I need your wisdom about ticks labels on ordinates for large numbers (>1e4).
The default behavior I have (0.87.4) is to display tick labels as "%.1f", and
write a string "x1e+..." above the top left corner of the current axes.
- When using "yaxis.tick_right()", the "x1e..." string stays above the top
left corner. That becomes an issue when using two different scales. How could
I force the 'mantissa' string to be on the same side as the axis it depends
on ?
- How could I change the number of decimals being displayed (for example,
"%.3f" instead of "%.1f"), while keeping the mantissa string ? (I tried a
"FormatStrFormatter("%.3f"), it's not what I want. With "Funcformatter(lambda
x,pos: "%.3f"%(x/1000)))", I lose the mantissa string...)
- Personally, I'm not keen on "3.0 x1e+4", I prefer "30 x1e+3". Is there a way
to get that ?
I guess that with a bit of trial/error with FuncFormatter and fig.text, I
should be able to get what I want, but I wanted to check whether there was
some easier solutions.
Thanks in advance for your help
P.

Added numpy-style all() to numerix. - EF It would be useful to have plot accept a 2-D array as well. Would patches for this be considered, or is there some reason why this can't work? At the moment, doing P.plot(z) where z is Nx2, raises RuntimeError: xdata and ydata must be the same length So it doesn't look as though this functionality will override any current feature.

[Matplotlib-users] Delete a plot line in interactive mode?
Hi, I'm new to matplotlib and am very impressed! I have a beginner type question: In interactive mode (using the GtkAgg backend) I'll plot multiple lines on a single subplot. The output got clutterred so I was looking for a pylab command to remove one of the plot lines but could not find any easy way to do this. Is this the case? Do I have to clear the current axes(cla) and replot all my lines minus the line I don't want? Something like this would be nice: line_nbr = 3 # delete third line on the current axes deleteline(line_nbr) Thanks, Mike __ Do You Yahoo!? Tired of spam? Yahoo!

You can write your own custom formatter to do this. You can use
ticker.ScalarFormatter as a guide.

Again, this could be handled by a custom formatter.

To do the whole job, we could handle a single NxK argument, and we could also handle pairs: Nx1, NxK NxK, Nx1 NxK, NxK I think it is clear what the behavior should be with any of the pairs; essentially they should be broadcast to the NxK, NxK case, resulting in K lines. In the single-argument NxK case, I think matlab plots subsequent columns against the first column. Is this what you would like? The alternative would be to plot each column against the row index, which is what happens in the Nx1 case, but I suspect the matlab-compatibility argument wins out here. Also, this maintains consistency with the original request for Nx2, which I assume was for plotting the second column against the first. I certainly would not want to have NxK behavior change as K goes from 2 to values larger than 2. Eric - Using Tomcat but need to do more? Need to support web services, security?

I am plotting results of graphs, graphs which have a certain number of edges. So I wanted to plot some statistic vs. number of edges. But the number of edges was not varied in a linear way but I have a list of which edges. So: edges=[54, 76, 80, 100]stats=[5.423, 23.226, 4.1, 6.93]So basically I wanted t=arange(len(stats) as my x-axis but edges for the labels (but only if it lies on a major tic). So I did: majorFormatter = ticker.FuncFormatter(lambda x, pos: labels[int(x)]) axis.xaxis.set_major_formatter(majorFormatter)If anyone knows a better way I would love to know.

You just have to tell matplotlib to use Agg as your backend -- pylab
will respect the default backend, whether it is a GUI, Agg or PS.
There are several ways to choose the backend
* make it permanent by setting your backend to 'Agg' in matplotlibrc
* change it on a per script basis exterally by launching with the -d
option
> python myscript.py -dAgg
> python myscript.py -dPS
> python myscript.py -dGTKAgg
* probably best for a web app, use the matplotlib "use directive".
This must be done *before* importing pylab
import matplotlib
matplotlib.use('Agg')
import pylab
plot and save
This is discussed at http://matplotlib.sf.net/backends.html

[Matplotlib-users] 2D Intensity Plots of Titan
I am trying to map the surface of Saturn's largest moon, Titan for a summer research project. As a rough draft, I would like to plot the temperature (colored red) at the longitude(x) and latitude(y) coordinates. My data file is tab delimited in three columns (x,y,T). I am also missing some x,y locations, which I would like to leave blank. As a final report, I would like the data point to be able to take on different geometries (circle, hexagon, arbitrary shape, etc) and different sizes as well as be able to overlap with neighboring data points. Finally, I would like to be able to plot this not on a rectangular cartesion coordinate system, but on a planetographic (global projection) coordinate system. I've spent two days trying everything from gnuplot, matlab, matplotlib and others trying to do this, but to no avail. Any suggestions would be very welcomed. - Using Tomcat but need to do more?

[Matplotlib-users] embedded python and matplotlib
I am a newbie to python, numpy, and matplotlib, and I like what I have seen so far. I have been wishing for a long time there was an open alternative to matlab, and when I heard about numpy and matplotlib, I tried them out immediately. Anyway, I am running python embedded in a C++ WX app. I just discovered matplotlib, so I tried it out. From the interactive python shell (vanilla FC5 linux install of python and matplotlib) everything works fine. The show() command blocks. In my application, I use the PyRun_SimpleFile command to execute user selected python files on a separate thread. That has seemed to work fine for several weeks on scripts using numpy and such. When I use matplotlib, however, the show() command does not block, and then strange things happen when I try to close the Figure window. On the first close it reopens the window right back up. On the second close attempt it closes (gdb splits out zombie thread messages), and then if I try to execute another script with a show() command in it it sometimes seg faults, sometimes works, but in general causes my program to behave strangely. So my question is: what is the correct way to setup python and/or matplotlib when running python embedded? Is there a way to make show() blocking when using embedded python (I am not sure this will solve any problems). Thanks, Lane Brooks - Using Tomcat but need to do more?

That's not the behavior I would have expected. I would have expected each row to be plotted as a funtion of the column index, just like plot([1,2,3,4]) is done now, but with each row in a different color. I would like plot([1,2,3,4], array([[1,2,3,4],[2,3,4,5]])) to plot two lines as a function of the single x-list, and I would like plot(array([[1,2,3,4],[2,3,4,5]]), array([[1,2,3,4],[2,3,4,5]])) to take the next obvious step.

I *think* matlab > does this, but its been so long since I used it... I was afraid someone would bring up these possibilities... One of the problems with fancy argument handling is that there are many ways it can be done, so we have to decide on the behavior we want; and inevitably this will surprise (and probably irritate) some people just as it pleases others. (Other problems include complex code, complex documentation, and runtime overhead. For interactive use, however, fancy argument handling may be worth the trouble.) We are going to have some tradeoffs among matlab compatibility, internal consistency, and adherence to the underlying data storage model. Here is what Matlab does (and in one respect it is not what I thought I remembered): 1) Given a single NxK matrix, it plots each column against the row index. 2) Given a vector and an NxK, it plots each column against the vector. 3) Given an NxK and a vector, it plots the vector against each column. 4) Given an NxK and an NxK it plots each column from the second against the corresponding column of the first. I think this is a good model: fairly simple, consistent, intuitive, and covers a good range of real-life situations. It differs from what I thought I remembered, and from what I think Stefan requested, in that, given an Nx2, it does not plot the second column against the first. That behavior, however, does not generalize nicely to NxK for any K!=2, so I now think we should choose either one or the other. A virtue of Stefan's Nx2 proposal is that it is consistent with the changes I made to elsewhere so that paths can be specified as Nx2 arrays; this, in turn, was consistent with the original specification as sequences of (x,y) tuples. But plot has never used sequences of (x,y) tuples, so the argument for the Nx2 form is weaker here. I don't know whether the reason Matlab chooses the columns as the data vectors is because of the Fortran storage order Matlab uses, or whether there is some other reason. Personally I am very comfortable with it, perhaps simply because of my Matlab experience. I think part of it is that columns in a table seem more natural as data vectors than rows, however; tables are usually oriented so that columns (fields) are different variables, and the row index is the sample number, or time, or a spatial coordinate. To summarize, the options seem to be: 1) Leave plot argument parsing alone. 2) Accept an Nx2 array in place of a pair of arguments containing x and y. 3) Implement the Matlab model. 4) Implement the Matlab model, but taking rows instead of columns in an X or Y array that is 2-D. I am open to arguments, but my preference is the Matlab model. I don't think that the difference in native array storage order matters much. It is more important to have the API at the plot method and function level match the way people think. Eric - Using Tomcat but need to do more? Need to support web services, security?

Re: [Matplotlib-users] embedded python and matplotlib
I found that using any of the non-GTK backends--like QTAgg or WXAgg--caused show() to block and at stopped the thread issues. I am not sure the implications of this, but it works for now.

Stefan, To reply more directly to your proposal now that I have thought about it more: although I see the logic in it, I don't see much gain from your Nx2 idea; it not very hard to simply write P.plot(z[:,0], z[:,1]). Furthermore, implementing your idea would not conflict with present behavior, but it would interfere with an alternative version of fancy argument handling that I think would be much more generally useful.
