change difference of min/max points

[adrian-schnell]

With your help, I was able to add the marks for min and max. Thanks again for that.

Now I want to make the difference between the two lines bigger.
The chart should start at about the middle of the screenshot - the max line should stay.
Can you give me a hint, what and how to change the code to get this result?

Hi again @rootilein!
You are very welcome.
I'm not sure if I understand correctly what you are trying to achieve here. Do you basically want the bottom of the graph to be lower in the UIView?

sorry for the bad explanation :D
I want to make the Peak-to-peak amplitude bigger - but the max Y values should stay at the place they are at the moment. hope now my problem is clear?

No problem!
If I'm correct, your changed the Padding in BEMSimpleLineGraphView.m to 200. Try to play around with this value (I would reduce it).
Keep it mind that you have to use the same value for the min line too:

    float minYPosition = (self.myGraph.frame.size.height - padding) - ((min - min) / ((max - min) / (self.myGraph.frame.size.height - padding))) + 30;

Let me know if it's not what you were looking for.
