Shading significance along signal traces #285

Closed Andres-Jaramillo closed 1 month ago

Andres-Jaramillo commented 2 months ago

Dear spm1d and Todd Sorry in advance for the simple question. Is there a method already implemented in the "plot class" for plotting/shading the significant regions (along x axis) in the plot on top of the signal traces, as in the plots I attach here? I was trying to find such in the documentation, code, and here in the forum. Kind regards to all. Andres

Hello Andres, This is not directly supported in the current version of spm1d but can be achieved using Matplotlib's axvspan. You can use cluster.endpoints to get the relevant x-axis positions, for example:

spmi  = spm1d.stats.ttest2(y1, y0).inference(0.05)
x0,x1 = spmi.clusters[0].endpoints
plt.axvspan(x0, x1, color='red', alpha=0.5)

Dear Todd, That just worked perfectly! Thanks
