Matplotlib1DViewer(vars[, title, xlog, ...])

Displays a y vs.
class fipy.viewers.matplotlibViewer.matplotlib1DViewer.Matplotlib1DViewer(vars, title=None, xlog=False, ylog=False, limits={}, legend='upper left', axes=None, **kwlimits)

Bases: AbstractMatplotlibViewer

Displays a y vs. x plot of one or more 1D CellVariable objects using Matplotlib.

>>> import fipy as fp
>>> mesh = fp.Grid1D(nx=100)
>>> x, = mesh.cellCenters
>>> xVar = fp.CellVariable(mesh=mesh, name="x", value=x)
>>> k = fp.Variable(name="k", value=0.)
>>> viewer = Matplotlib1DViewer(vars=(fp.numerix.sin(k * xVar) + 2,
...                               fp.numerix.cos(k * xVar / fp.numerix.pi) + 2),
...                 xmin=10, xmax=90,
...                 datamin=1.1, datamax=4.0,
...                 title="Matplotlib1DViewer test")
>>> for kval in fp.numerix.arange(0, 0.3, 0.03):
...     k.setValue(kval)
...     viewer.plot()
>>> viewer._promptForOpinion()

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

>>> viewer.title = "Matplotlib1DViewer changed"
>>> viewer.plot()
>>> viewer._promptForOpinion()
Parameters:

  • vars (CellVariable or list) – CellVariable objects to plot

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

  • xlog (bool) – log scaling of x axis if True

  • ylog (bool) – log scaling of y axis if True

  • limits (dict) – 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. (ymin and ymax are synonyms for datamin and datamax).

  • xmax (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale. (ymin and ymax are synonyms for datamin and datamax).

  • datamin (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale. (ymin and ymax are synonyms for datamin and datamax).

  • datamax (float, optional) – displayed range of data. Any limit set to a (default) value of None will autoscale. (ymin and ymax are synonyms for datamin and datamax).

  • legend (str) – place a legend at the specified position, if not None

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

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 lines

The collection of Matplotlib Line2D objects representing the plotted data.

property log

Whether data has logarithmic scaling

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.
