Remove value labels padding

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

I tried to hide the value labels using the dataSet.setDrawValues method.

What did you expect to happen?

I expected that the values will be hidden and the line chart's coordinates will be aligned to the grid.

What happened instead?

The coordinates are a bit off, as it looks like the value labels had some padding around them.

I currently solved the problem by adding a variable offset to the values, but this is a bad practice.

+1, had the same problem.

offset is ok

Nevermind, this was a problem due to forcing a certain number of labels in the left y-axis.
