- Dual (separate) Y-Axis

- Dragging / Panning (with touch-gesture)

- Finger drawing (draw values into the chart with touch-gesture)

- Highlighting values (with customizeable popup-views)

- Save chart to SD-Card (as image, or as .txt file)

- Read .txt file chart-data

- Predefined color templates

- Legends (generated automatically, customizeable)
