psyplot/psy-simple: v1.3.0: New background and mask formatoptions and more options for colorbar bounds

New background and mask formatoptions and more options for colorbar bounds

• a new background formatoption has been implemented that allows to set the facecolor of the axes (i.e. the background color for the plot)
• a new mask formatoption has been implemented that allows to mask the data based on a mask that can either be in the dataset or in a separate file (see #15)

• the bounds and other ticks (e.g. xticks, yticks, cticks) formatoptions have gained multiple new values (all backwards-compatible, see #13):

  • they now support discrete logarithmic and symmetric bounds/ticks via bounds='log' and bounds='symlog'.

  • The bounds and other tick formatoptions ([xticks, cticks, yticks, etc.]{.title-ref}) now support a dictionary as a value, e.g.:

    plotter.update(bounds={'method': 'rounded', 'percmin': 5})
    

  • You can specify vmin and vmax for color bounds and ticks which prevents their automatic estimation, e.g. via:

    plotter.update(bounds={'method': 'rounded', 'vmin': 50, 'vmax': 75})
    # or
    plotter.update(bounds=['rounded', None, None, None, 50, 75])
    

• values in the statusbar are only shown, if the drawn artist contains the cursor position, see #18
• psy-simple now requires matplotlib greater or equal than 2.0
• psy-simple has been moved from https://github.com/Chilipp/psy-simple to https://github.com/psyplot/psy-simple, see #7
• The color handling of the [color]{.title-ref} formatoption has been changed to allow appending of new data. The [colors]{.title-ref} attribute can be extended by the [color_cycle]{.title-ref} using the [extended_colors]{.title-ref} attribute (see #10)

• Fixed a bug to calculate color bounds for uniform data, see #9
• An issue has been fixed with the setting of colorbar ticks after updating the colorbar bounds (see #13)
