I have been using iOS [Charts](https://github.com/danielgindi/Charts) to create a bar graph. This is what I have so far:

I am having trouble achieving three things:

* Changing the x-axis labels from (0-7) to Monday, Tuesday, Wednesday, etc.
* Getting rid of the labels above the bars (1.0, 10.0, 20, etc.)
* How to get rid of the space between the bars and the axis at the very bottom

Help with any one of these would be greatly appreciated
