trafficstars

The order of entries for 2 column legends in a matplotlib plot is different from pgfplots. The first is top->bottom -> left ->right, while the second is top left -> top right -> 2nd top left ...... Any way to adapt this ? python pgf

`plt.plot(fi[0],cV[0],alpha = 0.0,label = "Test title") plt.plot(fi[0],cV[0],alpha = 0.0,label = " ") plt.plot(cs1[:,0],cs1[:,1],'k-', alpha = 1.0, label='a') # healthy plt.plot(cs4[:,0],cs4[:,1],'c-', alpha = 1.0,label='b') plt.plot(cs2[:,0],cs2[:,1],'k-', alpha = 1.0,label='c') # healthy plt.plot(cs9[:,0],cs9[:,1],'r-', alpha = 1.0,label='d') plt.plot(cs3[:,0],cs3[:,1],'k-', alpha = 1.0, label='e') # healthy plt.plot(cs7[:,0],cs7[:,1],'b-', alpha = 1.0,label='f') plt.plot(cs8[:,0],cs8[:,1],'b-', alpha = 1.0,label='g')

a = plt.gca()

handles,labels = a.get_legend_handles_labels() #handles = a.lines #a.legend(handles, labels,loc=2,bbox_to_anchor=(1.0,1.0)) a.legend(handles, labels,ncol=2,loc=4,bbox_to_anchor=(1.0,1.0))

a.set_xlabel('f [Hz]') a.set_ylabel('c$_s$ [$\frac{m}{s}$]') a.set_xlim(0, 400) a.set_ylim(0,4) a.grid()
