# Module plots

source code

Plotting facilities, based on Python's MPL library.

The Chart object is a facade which provides intuitive access to MPL's plotting objects. The following examples show a typical use of Chart:

1. Instantiation

       >>> chart = Chart()                     # a chart with a single plot
       >>> chart = Chart(rows=2, columns=2)    # a chart with 2x2=4 plots

2. Accessing plots (equivalent to MPL's subplots)

       >>> chart.plots[0]                      # first plot (at row=0, column=0)
       Plot (matplotlib.axes.AxesSubplot)
       >>> chart.plots[0, 1]
       Plot (matplotlib.axes.AxesSubplot)      # plot at row=0, column=1

3. Plotting

       >>> chart.plots[0].hist(...)
       >>> chart.plots[0].set_title('T')

       >>> chart.plots[1].scatter(...)
       >>> chart.plots[1].set_xlabel('X')

4. Using the GUI

       >>> chart.show()
       >>> chart.hide()

5. Saving as image

       >>> chart.save(filename, format=chart.formats.PDF)

If using the GUI, do not forget to dispose the chart at the end:

    >>> chart.dispose()

or simply use the chart in a context manager:

    >>> with Chart() as chart:
            chart...
