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

paragp / achartengine

AChartEngine is a charting library for Android applications. It currently supports the following chart types: line chart area chart scatter chart time chart bar chart pie chart bubble chart doughnut chart range (high-low) bar chart dial chart / gauge combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart cubic line chart All the above supported chart types can contain multiple series, can be displayed with the X axis horizontally (default) or vertically and support many other custom features. The charts can be built as a view that can be added to a view group or as an intent, such as it can be used to start an activity. The model and the graphing code is well optimized such as it can handle and display huge number of values. AChartEngine is currently at the 1.0.0 release. New chart types will be added in the following releases. Please keep sending your feedback such as we can continually improve this library.

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
