Title:  Patch for Issue 699 and 628 

- Fixes the issue where steps altering user datapoints
- Do not altering user data points for drawing lines with steps
(even stacked); just consider drawing with steps enables a different
kind of plotting and clipping on lines and areas; that assuming that
drawing with steps must always go horizontally and then verticaly
(like previous inserted datapoints).
