TimelineChartProviderBase

This class provides a base API for the chart providers. Chart provider is responsible for actually drawing the canvas and the chart. It is provided with data and view details by the timeline chart feature.

Chart canvas (implemented by subclasses) will be sized according to the timeline size. Width will be equal to the time axis size and height - to the timeline subgrid height. Canvas will be scrollable in horizontal direction and will remain at the top of the timeline view on vertical scroll.
