2 Different Butterfly Diagrams

All the Butterfly diagrams till now were plotted with latitude on the y axis, and time on the x axis. But normally data analysts plot the butterfly diagrams with sine of the latitude on the y axis.

This post is to show what difference is created by changing the axis.

                                                           Latitude V/s time butterfly plot

                                                        Sin(Latitude) V/s time butterfly plot

We can see that in the latter plot, the area from 0 to 60 degree latitude has been magnified, and the area from 60 to 90 degrees latitudes has been compressed near the poles.
