I am using MPAndroidChart library and have a set of data entries where the Y values are between 20 - 30 and I'm currently displaying it in a Line chart. However, I notice that there is a big gap because the Y-axis starts at 0 instead of 20.

How can I make Y-axis to start at the 20 instead of 0? Or even better the minimum of all y-values?
Thank you for your time!
