Matplotlib2DGridViewer(vars[, title, ...])

Displays an image plot of a 2D CellVariable object using Matplotlib.
class fipy.viewers.matplotlibViewer.matplotlib2DGridViewer.Matplotlib2DGridViewer(vars, title=None, limits={}, cmap=None, colorbar='vertical', axes=None, figaspect='auto', **kwlimits)

Bases: AbstractMatplotlib2DViewer

Displays an image plot of a 2D CellVariable object using Matplotlib.

>>> import fipy as fp
>>> mesh = fp.Grid2D(nx=50, ny=100, dx=0.1, dy=0.01)
>>> x, y = mesh.cellCenters
>>> xyVar = fp.CellVariable(mesh=mesh, name="x y", value=x * y)
>>> k = fp.Variable(name="k", value=0.)
>>> viewer = Matplotlib2DGridViewer(vars=fp.numerix.sin(k * xyVar) * 1000 + 1002,
...                 ymin=0.1, ymax=0.9,
...                 # datamin=1.1, datamax=4.0,
...                 title="Matplotlib2DGridViewer test")
>>> for kval in range(10):
...     k.setValue(kval)
...     viewer.plot()
>>> viewer._promptForOpinion()

>>> viewer.cmap = "ocean"
>>> viewer.log = True

>>> viewer.title = "Matplotlib2DGridViewer changed"
>>> viewer.plot()
>>> viewer._promptForOpinion()

Creates a Matplotlib2DGridViewer.

Parameters:

  • vars (CellVariable) – the Variable to display.

  • title (str, optional) – displayed at the top of the Viewer window

  • limits (dict, optional) – a (deprecated) alternative to limit keyword arguments

  • cmap (Colormap, optional) – the Colormap. Defaults to matplotlib.cm.jet

  • xmin (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale.

  • xmax (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale.

  • ymin (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale.

  • ymax (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale.

  • datamin (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale.

  • datamax (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale.

  • colorbar (bool, optional) – plot a color bar in specified orientation if not None

  • axes (Axes, optional) – if not None, vars will be plotted into this Matplotlib Axes object

  • figaspect (float, optional) – desired aspect ratio of figure. If arg is a number, use that aspect ratio. If arg is auto, the aspect ratio will be determined from the Variable’s mesh.

property axes

The Matplotlib Axes.

property cmap

The Matplotlib Colormap.

property colorbar

The Matplotlib Colorbar.

property fig

The Matplotlib Figure.

property id

The Matplotlib Figure number.

property log

Whether data has logarithmic scaling (bool).

plot(filename=None)

Update the display of the viewed variables.

Parameters:

filename (str) – If not None, the name of a file to save the image into.

plotMesh(filename=None)

Display a representation of the mesh

Parameters:

filename (str) – If not None, the name of a file to save the image into.

setLimits(limits={}, **kwlimits)

Update the limits.

Parameters:

  • limits (dict, optional) – a (deprecated) alternative to limit keyword arguments

  • xmin (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • xmax (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • ymin (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • ymax (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • zmin (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • zmax (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • datamin (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

  • datamax (float, optional) – displayed range of data. A 1D Viewer will only use xmin and xmax, a 2D viewer will also use ymin and ymax, and so on. All viewers will use datamin and datamax. Any limit set to a (default) value of None will autoscale.

property title

The text appearing at the top center.

(default: if len(self.vars) == 1, the name of the only Variable, otherwise "".)

property vars

The Variable or list of Variable objects to display.
