Data.plot_xyz

Data.plot_xyz(xcol=None, ycol=None, zcol=None, shape=None, xlim=None, ylim=None, projection='3d', **kargs)

Plot a surface plot based on rows of X,Y,Z data using matplotlib.pcolor().

Parameters:

• xcol (index) – Xcolumn index or label

• ycol (index) – Y column index or label

• zcol (index) – Z column index or label

Keyword Arguments:

• shape (tuple) – Defines the shape of the surface (i.e. the number of X and Y value. If not provided or None, then the routine will attempt to calculate these from the data provided

• xlim (tuple) – Defines the x-axis limits and grid of the data to be plotted

• ylim (tuple) – Defines the Y-axis limits and grid of the data data to be plotted

• cmap (matplotlib colour map) – Surface colour map - defaults to the jet colour map

• show_plot (bool) – True Turns on interactive plot control

• title (string) – Optional parameter that specifies the plot title - otherwise the current DataFile filename is used

• save_filename (string) – Filename used to save the plot

• figure (matplotlib figure) – Controls what matplotlib figure to use. Can be an integer, or a matplotlib.figure or False. If False then a new figure is always used, otherwise it will default to using the last figure used by this DataFile object.

• plotter (callable) – Optional argument that passes a plotting function into the routine. Default is a 3d surface plotter, but contour plot and pcolormesh also work.

• projection (string or None) – Whether to use a 3D projection or regular 2D axes (default is 3D)

• **kargs (dict) – A dictionary of other keyword arguments to pass into the plot function.

Returns:

A matplotlib.figure instance
