Example of a single figure with two items

This example shows the use of two plot items, one to plot a red line and the second to plot blue squares.

>>> from pyclaw.data import ClawPlotData
>>> from pyclaw.plotting import plotframe

>>> plotdata = ClawPlotData()
>>> plotdata.outdir = 'example-acoustics-1d'

>>> # Figure:
>>> plotfigure = plotdata.new_plotfigure(name='Solution', figno=1)
>>> plotfigure.kwargs = {'figsize':[5,3]}

>>> # Axes:
>>> plotaxes = plotfigure.new_plotaxes(name='Pressure')

>>> plotitem = plotaxes.new_plotitem(name='Pressure line', plot_type='1d')
>>> plotitem.plot_var = 0       # q[0] is the pressure
>>> plotitem.plotstyle = '-'
>>> plotitem.color = '#ff0000'   # could use 'r' or 'red' or '[1,0,0]'

>>> plotitem = plotaxes.new_plotitem(name='Pressure points', plot_type='1d')
>>> plotitem.plot_var = 0        # q[0] is the pressure
>>> plotitem.plotstyle = 's'     # squares
>>> plotitem.color = 'b'

>>> # plot one frame:
>>> plotdata.plotframe(4)
