Plotting experiment results
This tutorial sections covers plotting the results of an experiment.
Once the experiment execution completes, we can plot the result trajectories from the simulation.
To fetch the case trajectories for a given experiment the get_cases()
method can be
called on the experiment and further it could be checked if the cases did simulate successfully by calling
the is_successful()
method on the case. The get_trajectories()
function can be called on the individual case
objects to
fetch the Result
class object for that specific case.
To plot the results, the variable names of interest could be passed as index variables on the Result
class object:
import matplotlib.pyplot as plt
plt.figure(1)
plt.clf()
for case in experiment.get_cases():
if case.is_successful():
result = case.get_trajectories()
plt.plot(result['time'], result['inertia1.phi'])
plt.grid()
plt.show()
If the user wishes to fetch many result variables together, the below workflow could be followed:
result = experiment.get_trajectories(['inertia1.phi', 'time'])
height_1 = result['case_1']['inertia1.phi']
time_1 = result['case_1']['time']
height_2 = result['case_2']['inertia1.phi']
time_2 = result['case_2']['time']
height_3 = result['case_3']['inertia1.phi']
time_3 = result['case_3']['time']
