changes to plot in api.py, not reflected

[akritikts]

for i in gt_overall.columns:

            plt.figure()            
            #plt.plot(self.test_mains[0],label='Mains reading')
            plt.plot(gt_overall[i],label='Ground Truth')
            for clf in pred_overall:                
                plt.plot(pred_overall[clf][i],label=clf)
                plt.xticks(rotation=90)
            plt.title(i)
            plt.legend()
        plt.show()

The labels on the x-axis are not rotated.

I don't see how that's a NILMTK-contrib or even NILMTK issue.
