Fill below line color sometimes doesn't fill entirely or overlaps the line chart after a zoom operation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run the ChartEngine project demo
2. Launch the "Random Value Chart" and then "Line Chart" scenario
3. when zooming in and out, the white fill color sometimes doesn't fill 
completely the path below the blue line chart. You can see the details in the 
first attached file. In the second file there's an example of the problem 
happening in my android app (Barometer Monitor). In such case the fill color 
fills an area that is beyond the chart line. Also in this second example, the 
problem happens after a zoom operation.

What is the expected output? What do you see instead?
It should fill only and entirely the area below the chart line

Also experiencing this, on version 1.1.0.
This is a pretty serious bug, any chance it will be fixed?
