Switch from Grouped Bar chart back to normal

[elliotcz97]

What did you do?

I made a Grouped Bar chart, and its working fine. I also have a Bar chart which works also.
And i have a segmented controller which when changed sets the dataset for the chart

What did you expect to happen?

I wanted to have all of my 3 kinds of dataset presented how it should be.
This is how the Grouped Bar chart looks:

This is the normal Bar Chart

What happened instead?

After i switch from the grouped back to the normal my bars get thicker and the view looks zoomed in, but when i tried to set the zoom to 0 it still looked the same.
