• Show/hide all: hide or show all plots
• Reset line styles: reset the line color, line width, line style and marker to the default cycler

Operations

These operations apply to the selected plots.

• Average: calculate the power average and plot the result in the same figure
• Difference: calculate the difference - y values are simply subtracted, without any conversion to power
• Sum: calculate the sum, with the option to weigh each differently and a choice between summing power or decibels
• Export: export as Numpy array (.npz), Spreadsheet (.xlsx) or Comma Separated Values (.csv)

Arrange

Move the selected plots up or down in the list. Multiple plots can be moved simultaneously.
