contour_data

Context: visualization

Synopsis

Contour the values of an image data set.

Syntax

contour_data(id=None, replot=False, overcontour=False, **kwargs)

id - int or str, optional
replot - bool, optional
overcontour - bool, optional

Examples

Example 1

Plot the data from the default data set:

>>> contour_data()

Example 2

Contour the data and then overplot the data from the second data set:

>>> contour_data()
>>> contour_data(2, overcontour=True)

PARAMETERS

The parameters for this function are:

Parameter Definition
id The data set that provides the data. If not given then the default identifier is used, as returned by `get_default_id` .
replot Set to True to use the values calculated by the last call to `contour_data` . The default is False .
overcontour If True then add the data to an existing plot, otherwise create a new contour plot. The default is False .
