Storylines with matplotlib.pyplot

Question

I am trying to plot vertical lines in a log chart

xv1 = 10 plt.semilogy(t,P,'b') plt.semilogy(t,Pb,'r') plt.vlines(xv1,-1,1,color='k',linestyles='solid') plt.xlabel('Time [s]') plt.ylabel('P [Pa]') plt.grid() plt.show() 

Versions are not displayed in the graph (this is done for plt.plot)

Any ideas? Thanks!

You can use axvline to build vertical lines that span the entire range of plots. Then your code could read

 xv1 = 10 plt.semilogy(t, P, 'b') plt.semilogy(t, Pb, 'r') plt.axvline(xv1, color='k', linestyle='solid') plt.xlabel('Time [s]') plt.ylabel('P [Pa]') plt.grid() plt.show()
