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.

Unexpected behaviors with MathHelper.NULL_VALUE values #265

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hi,
I have some problems with MathHelper.NULL_VALUES.

To describe this problems I make two simple examples (based on 
SensorValuesChart.java in the demo app) : 
In the first example I have 5 lines whith 3 values. The first value of each 
line is MathHelper.NULL_VALUE (for example : MathHelper.NULL_VALUE, 1000, 1300)
In this example the problem is that the displayed value of the second value 
1000 is 1.7976931348623157E+308 in place of 1000.

In the second example I have already 5 lines with 3 values. Only the first 
value of each line is set. The two others are set to MathHelper.NULL_VALUE (for 
example : 1000, MathHelper.NULL_VALUE, MathHelper.NULL_VALUE).
In this example the problem is that the first value is not displayed although 
i'm using "setDisplayChartValues(true)";

You can find the examples in attach files.

I don't know if it's an issue or a wrong usage.

Thanks.
