Visualization class: FC/PSD/TS/etc.

Figure out the data structure.

• Physiological analytics

• Phase plane analysis

• PLS method

#101 was done
figure out if we want a plotting object or append as method to other object
next step is a proposed API for plotting

[P-Oveisi]

We can approach it in two ways:

1. The visualization functions would be extra methods that we can add to data objects
2. We could define a visualization object which would take in the data obj to be plotted + the representation we want (e.g., time series, PSD, FC mat, etc.) and the viz object will do the plotting.

I think the first option would make more sense if the data to be plotted isn't too complex. This would be similar to mne.evoked.plot() method in the MNE library.

In the case of more complex plots (for example 3D source localization) the second way would be more ideal. This is similar to the Brain object in mne (mne.viz.Brain).

What are people's thoughts? How do you think we should proceed?

[Andrew-Clappison]

John Recommendation: For simpler figures taking only a few lines of code then write them explicitly in examples, for more complex plots with many lines then have them encapsulated in methods/functions

[Andrew-Clappison]

Current focus to improve the figures in eg 003r and eg 004r

[P-Oveisi]

To do for Parsa

1. look at the examples -> decide which ones need improvement
2. Implement improvements as codes within the notebook itself
3. Then determine which visualizations merit from being packaged as extra methods for each objects

• (focus on example 3 and 4 visualizations)

[P-Oveisi]

Will make into MNE object to use MNE visualization funcitons.

Can also add the montage data to use .plot_joint() more comprehensive plots.

[P-Oveisi]

Added some code to generate clean-up visualizations:

However, having issues when trying to build the html files:

Extension error:
Here is a summary of the problems encountered when running the examples

Unexpected failing examples:
/external/rprshnas01/netdata_kcni/jglab/MemberSpaces/po/lab/repos/whobpyt_po_fork/examples/eg004r__fitting_JR_example.py failed leaving traceback:

Which seems to happen because the example data is being downloaded from a gdrive which doesn't have public access:

I think the folder is owned by @JohnWangDataAnalyst . Can you adjust the access please?
