pyart.graph.GridMapDisplay.plot_grid

GridMapDisplay.plot_grid(field, level=0, vmin=None, vmax=None, norm=None, cmap=None, mask_outside=False, title=None, title_flag=True, axislabels=(None, None), axislabels_flag=False, colorbar_flag=True, colorbar_label=None, colorbar_orient='vertical', ax=None, fig=None, lat_lines=None, lon_lines=None, projection=None, embelish=True, ticks=None, ticklabs=None, imshow=False, **kwargs)[source]

Plot the grid using xarray and cartopy.

Additional arguments are passed to Xarray’s pcolormesh function.

Parameters

  • field (str) – Field to be plotted.

  • level (int) – Index corresponding to the height level to be plotted.

Other Parameters

  • vmin, vmax (float) – Lower and upper range for the colormesh. If either parameter is None, a value will be determined from the field attributes (if available) or the default values of -8, 64 will be used. Parameters are used for luminance scaling.

  • norm (Normalize or None, optional) – matplotlib Normalize instance used to scale luminance data. If not None the vmax and vmin parameters are ignored. If None, vmin and vmax are used for luminance scaling.

  • cmap (str or None) – Matplotlib colormap name. None will use default colormap for the field being plotted as specified by the Py-ART configuration.

  • mask_outside (bool) – True to mask data outside of vmin, vmax. False performs no masking.

  • title (str) – Title to label plot with, None will use the default generated from the field and level parameters. Parameter is ignored if the title_flag is False.

  • title_flag (bool) – True to add title to plot, False does not add a title.

  • axislabels ((str, str)) – 2-tuple of x-axis, y-axis labels. None for either label will use the default axis label. Parameter is ignored if axislabels_flag is False.

  • axislabels_flag (bool) – True to add label the axes, False does not label the axes.

  • colorbar_flag (bool) – True to add a colorbar with label to the axis. False leaves off the colorbar.

  • colorbar_label (str) – Colorbar label, None will use a default label generated from the field information.

  • colorbar_orient (‘vertical’ or ‘horizontal’) – Colorbar orientation.

  • ax (Axis) – Axis to plot on. None will use the current axis.

  • fig (Figure) – Figure to add the colorbar to. None will use the current figure.

  • lat_lines, lon_lines (array or None) – Location at which to draw latitude and longitude lines. None will use default values which are reasonable for maps of North America.

  • projection (cartopy.crs class) – Map projection supported by cartopy. Used for all subsequent calls to the GeoAxes object generated. Defaults to PlateCarree.

  • emblish (bool) – True by default. Set to False to supress drawinf of coastlines etc… Use for speedup when specifying shapefiles. Note that lat lon labels only work with certain projections.

  • ticks (array) – Colorbar custom tick label locations.

  • ticklabs (array) – Colorbar custom tick labels.

  • imshow (bool) – If used, plot uses ax.imshow instead of ax.pcolormesh. Default is False.
