OMG, it doesn't start at zero!

It's ok not to start the Y axis at zero with a curves chart, it doesn't mis-represent the datas, it just ommits an area empty of datas.

But with eras or volumes graphs, it's a different story.
The volume of the boxes are supposed to be proportional to the values. The zone you have ommitted would not be empty but show MOST of the datas.

I remember when I first posted the graph below, you bashed me because months with no datas were not showing.
I then corrected the graph, which made even more obvious the point I was trying to make. (The March 2003 peak)



Why don't you correct your own graph and show us what it would like if boxes were proportional to the datas like it should be.

If you don't, I will.
