Title: Reference lines + set chart style on chart creation

Hi!
I've added some changes to GraphView:
1. Horizontal reference lines with labels (for example to show top and low edges of normal temperature range, etc);
2. Add constructor to set chart style (GraphViewStyle) on creation of chart object;
