How do you use Matplot?

Matplotlib is designed to be as usable as MATLAB, with the ability to use Python and the advantage of being free and open-source. Each pyplot function makes some change to a figure: e.g., creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates the plot with labels, etc.

How do you refresh a plot in MATLAB?

Link the plot to the workspace variables by setting the data source properties of the plotted object to ‘x2’ and ‘y2’ . Then, update x2 and y2 in a for loop. Call refreshdata and drawnow each iteration to update the plot based on the updated data.

How do you extract data from a graph in Python?

Steps

1. Set the figure size and adjust the padding between and around the subplots.
2. Create y data points using numpy.
3. Plot y data points with color=red and linewidth=5.
4. Print a statment for data extraction.
5. Use get_xdata() and get_ydata() methods to extract the data from the plot (step 3).
6. Print x and y data (Step 5).

How do I visualize raw data in Python?

To visually inspect your raw data, you can use the python equivalent of mne_browse_raw . The channels are color coded by channel type. Generally MEG channels are colored in different shades of blue, whereas EEG channels are black. The channels are also sorted by channel type by default.
