[Matplotlib-users] Isobar plots of spatial pressure data
Hi all, Assume that we have knowledge of pressure values at certain irregular grid points in 3D, i.e. p_i(x_i, y_i, z_i) i = 1,(1),N where N denotes the number of grid points. Usually N = 7e5. Is it possible to create an isobar plot using matplotlib ? How can I achieve it ? Nils -- New Year. New Location. New Benefits. New Data Center in Ashburn, VA.

Hi Ben, I have attached a sample scatter plot. The task is to add lines to the scatter plot.

It defaults to a draw mode of 'box', but you can set it to line so that it looks like a ruler widget. http://matplotlib.org/api/widgets_api.html#matplotlib.widgets.RectangleSelector I can imagine that you could set up a selector callback that could then query the data on the graph to snap the final line to the nearest points on the graph, creating a Line2D object on the fly.

This is because it is not an instance of ScalarMappable, which is what
colorbar() requires as its argument.

Use scalarMap as the argument instead of heatmap. I think you will need
to provide either the cax or the ax kwarg in addition.
examples/api/colorbar_only.py might also be helpful.

The following snippet doesn't show the desired effect.
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
fig = plt.figure(figsize=(10,8))
ax = fig.gca(projection='3d')
ax.grid(color='r',linestyle='-',linewdith=2)
A (somewhat) undocumented feature (and is not guaranteed to work in the
future!) is the axis's _axinfo dictionary.
# This is a temporary member variable.
# Do not depend on this existing in future releases!
self._axinfo = self._AXINFO[adir].copy()
self._axinfo.update({'label' : {'space_factor': 1.6,
'va': 'center',
'ha': 'center'},
'tick' : {'inward_factor': 0.2,
'outward_factor': 0.1},
'ticklabel': {'space_factor': 0.7},
'axisline': {'linewidth': 0.75,
'color': (0, 0, 0, 1)},
'grid' : {'color': (0.9, 0.9, 0.9, 1),
'linewidth': 1.0},
})
where _AXINFO is a class-level attribute defined as:
# Some properties for the axes
_AXINFO = {
'x': {'i': 0, 'tickdir': 1, 'juggled': (1, 0, 2),
'color': (0.95, 0.95, 0.95, 0.5)},
'y': {'i': 1, 'tickdir': 0, 'juggled': (0, 1, 2),
'color': (0.90, 0.90, 0.90, 0.5)},
'z': {'i': 2, 'tickdir': 0, 'juggled': (0, 2, 1),
'color': (0.925, 0.925, 0.925, 0.5)},
}
This information used to be hard-coded throughout the axis3d.py module. I
consolidated it all into this dictionary for each Axis3D instance. So, you
should be able to create your Axes3D object, and then do something like the
following:
ax = fig.gca(projection='3d')
ax.xaxis._axinfo['grid'].update({'color': 'r', 'linewidth': 2})
ax.xaxis._axinfo['color'] = 'white'
(Note: untested code!) I don't think the linestyle can be specified,
though. At some point, I probably should get the Axes3D.grid() function
defined to mess around with this _axinfo modify the _axinfo dictionary.
I hope that helps!

Adding a button is easy... Adding cross-platform printer
capability is not.
The only way I envision it could happen is if the GUI
toolkits have some
sort of printing API. We already can convert to
postscript.
Ben Root
A customization of the navigation toolbar is possible. I
have used the qt4 backend.
However the quality of the print-out is poor using
QPrinter. Moreover the frame including the navigation
toolbar is printed.
How can I omit that ?
How can I improve the quality of the hardcopy.
I have attached the program.
Any hint would be appreciated.

Ben was also right in that you could subclass
FuncAnimation and
override/extend methods. This would have the benefit of
giving more
control over the handling of seek(). (Something else for
my todo

from matplotlib.figure import Figure
from matplotlib.backends.backend_qt4agg import

from matplotlib.backends.backend_qt4agg import

# create a simple main widget to keep the figure
self.mainWidget = QWidget()
self.setCentralWidget(self.mainWidget)
layout = QVBoxLayout()
self.mainWidget.setLayout(layout)
# create a figure
self.figure_canvas = FigureCanvas(Figure())
layout.addWidget(self.figure_canvas, 10)
# and the axes for the figure
self.axes =
self.figure_canvas.figure.add_subplot(111)
# add a navigation toolbar
self.navigation_toolbar =
NavigationToolbar2(self.figure_canvas, self)
layout.addWidget(self.navigation_toolbar, 0)
# create a simple widget to extend the navigation
toolbar
anotherWidget=QLineEdit()
# add the new widget to the existing navigation
toolbar
self.navigation_toolbar.addWidget(anotherWidget)
if __name__==__main__:
app=QApplication(sys.argv)
mw=ViewWidget()
mw.show()
sys.exit(app.exec_())
Hope that helps ...
Best regards

Hi Jens,
Thank you very much for your response.
Hence I have tried
import sys
import numpy as np
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from matplotlib.figure import Figure
from matplotlib.backends.backend_qt4agg import
FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import
NavigationToolbar2QT as NavigationToolbar2
class ViewWidget(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
# create a simple main widget to keep the figure
self.mainWidget = QWidget()
self.setCentralWidget(self.mainWidget)
layout = QVBoxLayout()
self.mainWidget.setLayout(layout)
# create a figure
self.figure_canvas = FigureCanvas(Figure())
layout.addWidget(self.figure_canvas, 10)
# and the axes for the figure
self.axes =
self.figure_canvas.figure.add_subplot(111)
x = np.linspace(0.,2*np.pi,100)
self.axes.plot(x,np.sin(x))
# add a navigation toolbar
self.navigation_toolbar =
NavigationToolbar2(self.figure_canvas, self)
layout.addWidget(self.navigation_toolbar, 0)
# create a simple widget to extend the navigation
toolbar
# anotherWidget=QLineEdit()
printer = QPrinter()
anotherWidget= QPrintDialog(printer,self)
# add the new widget to the existing navigation
toolbar
self.navigation_toolbar.addWidget(anotherWidget)
if __name__==__main__:
app=QApplication(sys.argv)
mw=ViewWidget()
mw.show()
sys.exit(app.exec_())
How do I connect the plot with the printer ?
How can I replace the printer dialog by a small icon ?
I found the lines
a = self.addAction(self._icon('filesave.svg'),
'Save',
self.save_figure)
in backend_qt4.py

Hi Anton,
Thank you for your prompt reply.
I am aware of PIL.
However I didn't find an autocrop function within PIL.

region.show()
It would be nice to compute the box automatically.
Any idea ?

The scalar value of the picker is a epsilon tolerance in points (1 point = 1/72 inches) so you will need to set this distance to be small enough to only overlap one point when you click. If you want to only return a single point, you can write a custom picker function to return only the point closest to the click point. Unfortunately, I am not sure how to implement a custom picker function. Any pointer would be appreciated. Thanks in advance.

[Matplotlib-users] Vibrational modes of l-shaped membranes
Hi all, I am going to visualize mode shapes of L-shaped membranes using contour. So far, I have two lists xin, yin containing the coordinates of interior points (see bottom of mode.png) . A third list will contain the corresponding displacements u(xin,yin). xin [-0.9, -0.9, -0.9, -0.9, -0.9, -0.9, -0.9, -0.9, -0.9, -0.8, -0.8, -0.8, -0.8, -0.8, -0.8, -0.8, -0.8, -0.8, -0.7, -0.7, -0.7, -0.7, -0.7, -0.7, -0.7, -0.7, -0.7, -0.6, -0.6, -0.6, -0.6, -0.6, -0.6, -0.6, -0.6, -0.6, 0.6, 0.6, 0.6, 0.6, 0.6, 0.33326, 0.33326, 0.33326, 0.33326, 0.33326, 0.55536, 0.55536, 0.55536, 0.55536, 0.55536, 0.77768, 0.77768, 0.77768, 0.77768, 0.77768, 1.0, 1.0, 1.0, 1.0, 1.0] yin [-0.9, -0.8, -0.7, -0.6, 0.6, 0.33326, 0.55536, 0.77768, 1.0, -0.9, -0.8, -0.7, -0.6, 0.6, 0.33326, 0.55536, 0.77768, 1.0, -0.9, -0.8, -0.7, -0.6, 0.6, 0.33326, 0.55536, 0.77768, 1.0, -0.9, -0.8, -0.7, -0.6, 0.6, 0.33326, 0.55536, 0.77768, 1.0, 0.6, 0.33326, 0.55536, 0.77768, 1.0, 0.6, 0.33326, 0.55536, 0.77768, 1.0, 0.6, 0.33326, 0.55536, 0.77768, 1.0, 0.6, 0.33326, 0.55536, 0.77768, 1.0, 0.6, 0.33326, 0.55536, 0.77768, 1.0] How can I realize this task with mpl ? help (contour) yields contour(X,Y,Z) - X,Y specify the (x,y) coordinates of the surface. X, Y, and Z must be arrays with the same dimensions. Z may be a masked array, but filled contouring may not handle internal masked regions correctly. How do I build X,Y from my lists xin, yin ? Any pointer would be appreciated. Nils Using Tomcat but need to do more? Need to support web services, security?

From what I remmbr from my LaTeX years, you need to transform the jpeg to a format LaTeX can understand, viz '.ps' or '.eps' Check http://www2.eng.cam.ac.uk/~pmg26/hpage/teaching/graphics_LaTeX.html or the help/manual of the graphicx package, or google import jpeg latex Using Tomcat but need to do more?

Hi all,
I have generated some figures with matplotlib (savefig('test.png')
savefig(test.jpg')).
If I try to include them via
\includegraphics[width=8cm]{test.jpg}
I get
LaTeX Error: Cannot determine size of graphic in test.jpg (no BoundingBox).
I am using latest svn versions of numpy/scipy and matplotlib.
Any idea how to fix this problem ?
Nils
Sorry for the noise. It was just a missing \usepackage{graphicx} in the
header of my new tex file.
