Re: [jCharts-users] Exporting chart to JPEG

[Bent A. M. <me...@f1...>]

Hi

This is the code for my chart. I suppose that you are referring to the
line

double[][] data= new double[][]{ { 250, 45, -36, 66, 145, 80, 55 }
};

If not, you can see the whole code here:

String[] xAxisLabels= { "1998", "1999", "2000", "2001", "2002", "2003",
"2004" };
String xAxisTitle= "Years";
String yAxisTitle= "Problems";
String title= "CIBER";
DataSeries dataSeries = new DataSeries( xAxisLabels, xAxisTitle,
yAxisTitle, title );

double[][] data= new double[][]{ { 250, 45, -36, 66, 145, 80, 55 }
};
String[] legendLabels= { "Bugs" };
Paint[] paints=TestDataGenerator.getRandomPaints( 1 );

Stroke[] strokes= { LineChartProperties.DEFAULT_LINE_STROKE };
Shape[] shapes= { PointChartProperties.SHAPE_CIRCLE };
LineChartProperties lineChartProperties= new LineChartProperties(
	strokes, shapes );
AxisChartDataSet axisChartDataSet= new AxisChartDataSet( data,
	legendLabels, paints, ChartType.LINE, lineChartProperties );
dataSeries.addIAxisPlotDataSet( axisChartDataSet );

ChartProperties chartProperties= new ChartProperties();
AxisProperties axisProperties= new AxisProperties();
LegendProperties legendProperties= new LegendProperties();

AxisChart axisChart= new AxisChart( dataSeries, chartProperties,
	axisProperties, legendProperties, 1,1 );

Thanks!

regards
