RE: [jCharts-users] Y-Axis range - How is it set ?

[Liu, L. \(Exchange\) <LL...@Be...>]

Hi, Nathaniel:

	I did yAxis.setUserDefinedScale( 0, 0.000001); and
yAxis.setRoundToNearest(0); I also set yAxis.setNumItems((int)maxY +2);
and this seems to have made it work (Note: maxY is the maximum of Y
data). I have also attached a code section below. I did read the User's
guide downloaded from the Web but yet to experience more to utilize many
classes of JCharts. Can you tell me how I can use ScaleCalculator to
adjust the Y-axis scale? What is the difference between Auto- and
UserDefinedScaleCalculator ? Commented code did not work as expected.
Can you see why?

            AxisProperties axisProperties=3D new AxisProperties();
            DataAxisProperties yAxis=3D (DataAxisProperties)
axisProperties.getYAxisProperties();
           =20
//            UserDefinedScaleCalculator myScaleCalculator =3D new
UserDefinedScaleCalculator(0.0, 0.001);
//            myScaleCalculator.setMinValue(0);
//	      myScaleCalculator.setMaxValue(maxY);
//            myScaleCalculator.computeScaleValues();
//            yAxis.setScaleCalculator(myScaleCalculator);
//((DataAxisProperties)axisProperties.getYAxisProperties()).setUserDefin
edScale(0, maxY);
                                            =20
            LegendProperties legendProperties=3D new LegendProperties();

            Dimension dimension=3DjPanel_Graph.getSize();
            AxisChart axisChart=3D new AxisChart( dataSeries,
chartProperties, axisProperties, legendProperties, dimension.width,
dimension.height );

what is your rounding factor set to?  Did you take a look at the users
guide?

How
