[GNC] Report zoom in version 4.9

[TG]

Howdy all,

I'm sure I'm missing something obvious,

In previous version of gnucash I was able to pull up a line graph report 
and then draw a box on teh graph, which would cause the graph to zoom in 
on that section.

I upgraded to version 4.9 earlier this year and now I'm not able to zoom 
graphs at all, having to control size by pixel dimensions and start / 
end dates only.

Any suggestions, or was this feature simply removed?

thanks!
