I see -- you want to basically interpolate between points? I don't think there's anything built in to matplotlib to do that, but you could always do that interpolation outside and just update the graph more often.

eh.... Let me explain my problem in a different way: Every two seconds I get a value from a service. Let's say I over 8 seconds I get 1, 5, 10, 5 as values. So if my application updates the graph every two seconds, this will look choppy and ugly. This is because every two seconds, an entire line is added onto the graph between the two points. Imagine if I could control the drawing of said line though. If I could draw the individual pixels of the line every couple of ticks instead of just dumping a line in every two seconds, I will end up with a nice smooth animation. It may not be 100% real time anymore, but my focus on this personal project of mine is vanity, not practicality ;) I hope this better explains what I am trying to accomplish...

It looks like the version of Numpy installed on your machine is too old for the latest version of matplotlib. You'll need at least version 1.5, I believe (though we neglected to update the documentation about this requirement).

Have you looked at the simple_anim.py example -- other than the networking piece, it seems to do what you describe, and it's pretty fast. Maybe start from that and make changes until it gets slow in order to determine where the slowness comes from...?

I am receiving a number from a server every two seconds. I would like to plot this number.out over time for the past say... 30 polls. Would it be possible to use... Anything, to produce a smooth animation of the plot line getting drawn? As it stands now the animation is well... Quite choppy. ;) I'm using pygame currently to render my graphs on this full screen application I'm making just for my self. I am not bound to it though if there are better linux-only things out there. Thanks in advance, --alex |

I am new to python and when using Matplotlib 0.99.1.1 [Scientific Linux
6.3, Python 2.6] to plot I get the following error:
/usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621: DeprecationWarning: Use the new widget gtk.Tooltip
self.tooltips = gtk.Tooltips()
This is when the program reaches:
plt.show()
Where plt is the matplotlib.pyplot. Prior to this point of the code I am
able to produce pdf files of the figure by using plt.savefig(fname).
Reading other online comments I have tried to update Matplotlib. First I
installed the dependences via
sudo yum-builddep python-matplotlib
Then:
sudo yum install matplotlib
This then tells me that I have the latest version of matplotlib and
therefore does nothing. There are more recent versions available from
the Matplotlib website. I tried to install the latest version after
unpacking the tar.gz file. After using the command:
sudo python setup.py install
I get the message below ending with error:
command 'gcc' failed with exit status 1
Can anyone suggest a way to install the latest matplotlib or stop the
message I get with using plt.show()?

Not a bother. This is a fairly common problem because matplotlib, by
design, does not handle layouts for you. If you are looking for an
automated way of handling this, there is plt.tight_layout(), which is a
feature that was added in v1.2, IIRC, that tries adjusting certain spacing
and size parameters automatically in an effort to keep everything inside
the figure space. However, a solution like yours is often perfered because
it gives you explicit control over the plot, and is guaranteed to work the
same way, every time.
Cheers!

Ok, I should have read to docu before googling.
plt.xlabel("$x/l_F$", labelpad = -0.1)
did it.
Sorry for bothering...

Hello!
I have that snipped to create a plot:
import matplotlib.pyplot as plt
size = (6.1, 3.5)
fig = plt.figure(figsize=size)
plt.xlabel("$x/l_F$")
it's being saved as eps for latex. At the size given the "F" from l_F is
truncated just a little bit. It works well if I change y-size to 3.6 but that
makes latex place to figure on a seperate page which I do not want.
Is this behavior by design or a bug? How can I give just 0.1 more y-space to
the xlabel without altering the overall size?
Thanks,
Florian

A colormap works from 0 to 1, so that is its data coordinates. We merely label the ticks with the appropriate values. Try cbar.ax.yaxis.get_ticklabels(). Cheers! Ben Root |

Thanks Ben. I tried but still confused.
In [8]: fig,ax = plt.subplots()
In [9]: ax.plot(range(100))
Out[9]: [<matplotlib.lines.Line2D at 0x4cadb50>]
In [10]: ax.get_xticks()
Out[10]: array([ 0., 20., 40., 60., 80., 100.])
In [11]: ax.get_yticks()
Out[11]: array([ 0., 20., 40., 60., 80., 100.])
In [12]: draw()
In [13]: cs = ax.imshow(np.arange(100).reshape(10,10))
In [14]: draw()
In [15]: cbar = plt.colorbar(cs,ticks=np.arange(0,100,10))
In [16]: cbar.ax.get_yticks()
Out[16]:
array([ 0. , 0.1010101 , 0.2020202 , 0.3030303 , 0.4040404 ,
0.50505051, 0.60606061, 0.70707071, 0.80808081, 0.90909091])
there are many methods avaialbe for cbar.ax.yaxis object:
In [19]: cbar.ax.yaxis.get*tick*?
cbar.ax.yaxis.get_major_ticks
cbar.ax.yaxis.get_majorticklabels
cbar.ax.yaxis.get_majorticklines
cbar.ax.yaxis.get_majorticklocs
cbar.ax.yaxis.get_minor_ticks
cbar.ax.yaxis.get_minorticklabels
cbar.ax.yaxis.get_minorticklines
cbar.ax.yaxis.get_minorticklocs
cbar.ax.yaxis.get_ticklabel_extents
cbar.ax.yaxis.get_ticklabels
cbar.ax.yaxis.get_ticklines
cbar.ax.yaxis.get_ticklocs
cbar.ax.yaxis.get_ticks_position
I tried
In [20]: cbar.ax.yaxis.get_majorticklocs()
Out[20]:
array([ 0. , 0.1010101 , 0.2020202 , 0.3030303 , 0.4040404 ,
0.50505051, 0.60606061, 0.70707071, 0.80808081, 0.90909091])
But it doesn't give the tick locs as the normal axes?
could you explain a bit further?
thanks et cheers,
Chao

Thanks Ben. extendrect keyword is in mat 1.3, I didn't try this but I tried set_under and extend='min' with mat 1.2 and it works very nice. cheers, Chao On Tue, Jul 2, 2013 at 4:14 PM, Benjamin Root-2 [via matplotlib] < ml-...@n5...> wrote: > There is the "set_over" and "set_under" members of a colormap, and the > plt.colorbar() function takes an "extend='min'" argument to add an extra > color at the beginning of the colorbar.

Ian, thanks for you reply Using threshold like you described is not applicable as there is no guarantee of minimum distance between pattern objects. I wanted to replicate CGAL crust demo in Python, and in the meantime I found the algorithm by Nina Amenta: ======================================== compute Vor(P); let V be the Voronoi vertices of Vor(P); compute Del(P U V); E := 0; for each edge pq in Del(P U V) do if p in P and q in P E := E U pq; endif output E. ======================================== So, Voronoi vertices have property to cluster wanted objects in a manner that we can use edges of Delaunay triangulation from original points and Voronoi vertices of that same points, and simply check if they lay on original points. I used Deleanay and Voronoi functions from scipy.spatial and worth mentioning is that I had hard time finding that edges from triangulation can be found by this command: ======================================== t = Delaunay(PUV) edges = t.points[t.vertices] ======================================== Cheers > >Incidentally, if you have a Triangulation object then subsequent >calls to functions like triplot can be of the form triplot(triang), which >will be faster than repeated calls to triplot(xpoints, ypoints) as in the >latter case a separate Delaunay triangulation needs to be performed for >each triplot call. > >Ian |

Greetings! Relative newbie here. I'm trying to plot wind vectors using basemap quiver and to fit my ortho projection. This is essentially a hack of Jeff Whitaker's animate.py found at https://github.com/matplotlib/basemap/blob/master/examples/animate.py The data source I'm connecting to, however, has the latitudes in decreasing order, so I get the "lats and lons must be in increasing order!" exception when trying to use the transform_vector method which seems to be required to fit the vectors to the projection. (ugliness occurs when failing to transform) What would be the best way to transform latitudes (to increasing) as needed by transform_vector, while also accounting for the data order of my u and v grids? -kevin. -- View this message in context: http://matplotlib.1069221.n5.nabble.com/Basemap-transform-vector-for-decreasing-latitudes-tp41375.html Sent from the matplotlib - users mailing list archive at Nabble.com. |

[Apologies for cross-posting] The matplotlib developers want to hear from you! We are conducting a user survey to determine how and where matplotlib is being used in order to focus its further development. This should only take a couple of minutes. To fill it out, visit: https://docs.google.com/spreadsheet/viewform?fromEmail=true&formkey=dHpQS25pcTZIRWdqX0pNckNSU01sMHc6MQ <https://docs.google.com/spreadsheet/viewform?fromEmail=true&formkey=dHpQS25pcTZIRWdqX0pNckNSU01sMHc6MQ> Please forward to your colleagues, particularly those who don't read these mailing lists. Cheers, Michael Droettboom, and the matplotlib team |

Ran into a bug this morning with draggable annotations. It would seem that finalize_offset() forcibly overrides the annotation's textcoords status to "axes fraction" so it can set the coordinates properly. That's all well and good, but if you were using some text coordinates system other than "axes fraction" (say, for example, "data"), this can cause fun side effects such as annotations that used to pan around with the rest of the graph suddenly being frozen in place. :( Attached is a patch to restore the old textcoords mode in finalize_offset(). All it does is save the old textcoords mode before making the change to "axes fraction" and restores it afterwards. Hope this helps! -jo |

This is a constant source of confusion. The colorbar object should be thought of as just another subaxes. To get the ticks, you want the ticks from the colorbar's yaxis or xaxis object accordingly. Of course, I could have sworn we added a helper function for this at some point, but I could be wrong. I hope that helps!

There is the "set_over" and "set_under" members of a colormap, and the plt.colorbar() function takes an "extend='min'" argument to add an extra color at the beginning of the colorbar. Setting "extendrect=True", the added color will be rectangular instead of triangular. Hopefully that helps.

One way I could think of is to make two contingent mat.axes.Axes, with a smaller one setting as white backgroud, and the other bigger on holding the colorbar. Is there some better way?
