Hari,
To recycle the figure, try the following:
import matplotlib.pyplot as plt
def do_my_plot(par1, par2, well_id):
processed_data_object = processed_dict[well_id]
# Plot all the data
par1.plot(processed_data_object.raw_x,processed_data_object.raw_y).
par2.plot(....
# finally
plt.show()
# I tried fig.clf()
def plot_and_process_data():
plt.ion() # Turn on interactive mode
fig = plt.figure(figsize=(7,7)
ax = fig.add_subplot(1,1,1)
par1 =ax.twinx()
par2 = ax.twinx()
for well_id in list_of_384_well_ids:
par1.cla()
par2.cla()
process_data(well_id)
do_my_plot(par1, par2, well_id)
Note, this is completely untested, but it would be how I would go about it
at first. The "plt.ion()" turns on interactive mode to allow your code to
continue running even after the plot window appears (but does not end until
the last window is closed.). Of course, another approach would simply be
to do "fig.savefig()" after every update to the figure and never use show()
and ion() (essentially, a non-interactive head-less script).
Hopefully, this helps.
