Creates a Matplotlib2DViewer.

Parameters:

vars (CellVariable or FaceVariable) – rank-1 Variable to display
title (str, optional) – displayed at the top of the Viewer window
scale (float, optional) – if not None, scale all arrow lengths by this value
sparsity (int, optional) – if not None, then this number of arrows will be randomly chosen (weighted by the cell volume or face area)
log (bool, optional) – if True, arrow length goes at the base-10 logarithm of the magnitude
limits (dict, optional) – a (deprecated) alternative to limit keyword arguments
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.
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.
