Implement Strip Chart #30
Description
Implement a new chart type:
Strip Chart: implement a chart type with a scrolling display. This chart should plot values from left to right. If the screen is filled, new points are drawn at the rightmost point and old values are shifted to the left. Opposed to sweep-charts, in strip-charts, the line series never 'wraps' back from the right to the left screen border.
- should inherit from Base_Chart or XY_Chart, when refactoring issue # 17(Abstration layer) is finished
