Matplotlib/DeletingAnExistingDataSeries - SciPy wiki dump (original) (raw)
Each axes instance contains a lines attribute, which is a list of the data series in the plot, added in chronological order. To delete a particular data series, one must simply delete the appropriate element of the lines list and redraw if necessary.
The is illustrated in the following example from an interactive session:
x = N.arange(10)
fig = P.figure() ax = fig.add_subplot(111) ax.plot(x) [<matplotlib.lines.Line2D instance at 0x427ce7ec>]
ax.plot(x+10) [<matplotlib.lines.Line2D instance at 0x427ce88c>]
ax.plot(x+20) [<matplotlib.lines.Line2D instance at 0x427ce9ac>]
P.show() ax.lines [<matplotlib.lines.Line2D instance at 0x427ce7ec>, <matplotlib.lines.Line2D instance at 0x427ce88c>, <matplotlib.lines.Line2D instance at 0x427ce9ac>]
del ax.lines[1] P.show()
which will plot three lines, and then delete the second.
