Re: [Matplotlib-users] how to make mat.figure.Figure.add_axes generated axes adjustable with the interactive tool?
Hi, thanks. the attached is what I achieved so far. Looks quite nice. each subplot visible now actually contains two mat.axes.Axes object (with bottom and top spines invisible) which is created by using the fig.add_axes, before the place occupied by the two axes now is actually only one single subplot ojbect, which is created by using fig,axs = plt.subplots(2,3). something like this: for ax in axs.flatten(): #some way to find the position of the two new axes sub1 = fig.add_axes() sub2 = fig.add_axes() fig.delaxes(ax) Now the problem is that all the original subplots have been removed, replaced by 2X6 mat.axes.Axes, But they don't respond to any operation in the interacitve window (like, you can use your mouse to select the left/righ/wspace etc) I hope I am clear. thanks! cheers, Chao On Fri, Jul 26, 2013 at 5:55 PM, Sterling Smith [via matplotlib] ml-node+s1069221n41615...@n5.nabble.com wrote: Chao, You are right, fig.add_subplot does not support precise positioning. Why don't you send a picture of a sample layout you have obtained with add_axes? -Sterling On Jul 26, 2013, at 1:26AM, ChaoYue wrote: Dear Sterling, thanks for your answer. The idea is that I would like to add a subplot with precise position, as in the method of fig.add_axes? Does fig.add_subplot support this, I tried fig.add_subplot(position=(0.2,0.2,0.1,0.1)) but it does not work... thanks!

Can you use the add_subplot method of that figure instance to make your new axes? If so, then I think that they should respond to the new requests for left/right/bottom/wspace space. -Sterling On Jul 25, 2013, at 10:06AM, Chao YUE wrote: Dear all, First I make some subplots using the plt.subplots command, then I use mat.figure.Figure.delaxes to delete the axes, and add some small new ones in the same space by using mat.figure.Figure.add_axes, but I find after rendering the figure in the interative window, I cannot adjust the left/right/bottom/wspace etc in a interactive way, the old subplots that are generated using plt.subplots command will move, and the new ones generated using mat.figure.Figure.add_axes just don't move at all, so what should I do if I want the new ones also move? Because the interative window is really useful when you want to have figures quickly. thanks a lot for any hints. cheers, Chao -- *** Chao YUE Laboratoire des Sciences du Climat et de l'Environnement (LSCE-IPSL) UMR 1572 CEA-CNRS-UVSQ Batiment 712 - Pe 119 91191 GIF Sur YVETTE Cedex Tel: (33) 01 69 08 29 02; Fax:01.69.08.77.16 -- See everything from the browser to the database with AppDynamics Get end-to-end visibility with application monitoring from AppDynamics Isolate bottlenecks and diagnose root cause in seconds.

[Matplotlib-users] Scatter animations with colormaps
Hi all,
I'm trying to animate scatter plots on Matplotlib 1.2.1.
My code is as below:
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
import matplotlib.animation as anm
x = np.array([np.cos(i) for i in np.arange(0.0, 360.0, 9.0) / 180.0 * np.pi])
y = np.array([np.sin(i) for i in np.arange(0.0, 360.0, 9.0) / 180.0 * np.pi])
z = np.arange(0.0, 1.0, 0.025)
cdict = {
'red': (
(0.0, 0.0, 0.0),
(0.5, 0.5, 0.5),
(1.0, 1.0, 1.0)
),
'green': (
(0.0, 0.0, 0.0),
(0.5, 0.0, 0.0),
(1.0, 0.0, 0.0)
),
'blue': (
(0.0, 0.0, 0.0),
(0.5, 0.0, 0.0),
(1.0, 0.0, 0.0)
)
}
my_cmap = mpl.colors.LinearSegmentedColormap('my_colormap', cdict, 256)
fig = plt.figure()
ax = fig.add_subplot(111)
def init():
sct.set_offsets(([], []))
def update_sct(i, sct):
sct.set_offsets((x[i], y[i]))
return sct
sct = ax.scatter([], [], marker = 'o', s = 10.0, linewidth = 1.0, cmap =
my_cmap, c = [])
sct_anm = anm.FuncAnimation(fig, update_sct, fargs = (sct,), interval = 100,
frames = len(x))
ax.set_xlim((-2.0, 2.0))
ax.set_ylim((-2.0, 2.0))
plt.show()
Now I'm trying to set scatters' colors mapped by 'z'.
How can I set scatters' c values in each frame?
