I seem to be having a problem with acquiring the associated double value of a TimeSimpleDataset timeDataPoint.

For example:

TimeSimpleDataset tsd = new TimeSimpleDataset();
GregorianCalendar cal = new GregorianCalendar();
tsd.addTimeDataPoint(cal, 10.0);
(get dataPoint) ... ?

What method do I call to get both the time and associated double from the tsd?

I can get the X Value fine with:

tsd.getTimeXDataValue(0);

but the tsd.getTimeYDataValue() returns a gregorianCalendar, the same calendar saved for the x value, not the saved double I am expecting.

When I try to use the inherited SimpleDataset methods, it provides me with the incorrect number.

For example:
tsd.getDataPoint(0).getY() returns 0, not 10.

Is there a work around for this problem?

Normally you pass in arrays of data values to create the dataset, as all of our examples do. That defines which coordinate is the time coordinate, x or y. In your case you are using the default constructor where you must explicity set it.

TimeSimpleDataset tsd = new TimeSimpleDataset();
tsd.setXCoordinateType(ChartObj.TIME_COORDINATE);
GregorianCalendar cal = new GregorianCalendar();
tsd.addTimeDataPoint(cal, 10.0);

GregorianCalendar x = tsd.getTimeXDataValue(0);
double y = tsd.getYDataValue(0);
