Results
-------
Modify the ``run()`` method of the experiment as follows: ::
def run(self):
parabola = self.set_result("parabola", [], realtime=True)
for i in range(int(self.count)):
parabola.append(i*i)
time.sleep(0.5)
.. note:: You need to import the ``time`` module.
Commit, push and submit the experiment as before. While it is running, go to the "Results" dock of the GUI and create a new XY plot showing the new result. Observe how the points are added one by one to the plot.
After the experiment has finished executing, the results are written to a HDF5 file that resides in ``~/artiq-master/results/<date>/<time>``. Open that file with HDFView or h5dump, and observe the data we just generated as well as the Git commit ID of the experiment (a hexadecimal hash such as ``947acb1f90ae1b8862efb489a9cc29f7d4e0c645`` that represents the data at a particular time in the Git repository). The list of Git commit IDs can be found using the ``git log`` command in ``~/artiq-work``.
.. note:: HDFView and h5dump are third-party tools not supplied with ARTIQ.
