Infinite and NaN values resulted in bad looking graphs

What steps will reproduce the problem?
1. Add a Infinity or NaN value to a series
2. Graph the series

What is the expected output? What do you see instead?
That series will not display at all on the graph, or that data point will 
display with strange lines.

I think the expected result would be for all series data except for the NaN's 
and Infinities to be displayed (in the above example, 1, 2, 3, and 4 should be 
displayed).

To reproduce this issue, you can edit 
demo/org/achartengine/chartdemo/demo/chart/AverageTemperatureChart.java and 
change one of the data points to Float.POSITIVE_INFINITY or 
Float.NEGATIVE_INFINITY. I'm attaching a screenshot what the graph looks like 
when the data on line 66 is changed to:
    values.add(new double[] { 12.3, Float.POSITIVE_INFINITY, 13.8, 16.8, 20.4, 24.4, 26.4, 26.1, 23.6, 20.3, 17.2,
        13.9 });

What version of the product binary library are you using?
svn revision 320
