# Interactive Plotting Window

The $Z^2_n$ Software has a special window for interactive plotting of the periodogram, that makes possible selecting regions on the power spectrum, or changing parameters on the generated figure, just type plot on the terminal, for more information on the usage type help.

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 (z2n) >>> plot Interactive plotting window of the Z2n Software. Type "help" for more information. (plt) >>> help Documented commands (type help ): ======================================== save title xlabel xlim xscale ylabel ylim yscale Undocumented commands: ====================== exit help quit (plt) >>> 

You can verify if you are interacting with the periodogram itself or the plot figure at any point by checking the prefix on the terminal.

 1 2 3 (z2n) >>> 'Interacting with the periodogram' (plt) >>> 'Interacting with the plot figure' 

Important

If you are unable to see the plot of the power spectrum, it means that a required component is missing, and the $Z^2_n$ Software will not be able to execute the interactive backend and plot the periodogram. See known issues to better understand the problem and the solutions.
