Urgent Help JFreeChart

[jesusmgmarin]

Hello I need modify a chart generate. I use jfreechart-1.0.0.jar.
I have crateed a graph with a series of values,

but now I need to change my Y-axis, The graphs must show in depth. That is to say, in the Y-axis the Depth goes. The highest value of the Y-axis corresponds with value 0 and the values will grow downwards.

How can I do this??
I post my code for help:

Code: Select all

public JFreeChart XYLine2(String vInDep, String vDep){
     XYSeries series = new XYSeries("Leyenda de Línea");

     /*[b]arrayVars [/b]is a global variable that contains two columns and several rows. It contains the data to represent in the chart */
     for (int i=0; i<arrayVars.length; i++){
          if( (null != arrayVars[i][0]) && (null != arrayVars[i][1]) ){
               float x= Float.parseFloat(arrayVars[i][0]);
               float y= Float.parseFloat(arrayVars[i][1]);
               series.add(x,y);	
          }
     }
		
     XYDataset ColeccionDatos = new XYSeriesCollection(series);
	
     JFreeChart graph = ChartFactory.createXYLineChart(
          vDep+" vs "+vInDep,	//Tittle
          vInDep,		//X-axis
          vDep,		//Y-axis
          ColeccionDatos,	//Dataset
          PlotOrientation.HORIZONTAL,	//Orientation	
          false,     //Flag legend
          true,      //Flag tooltip
          false      //Flag URLs
     );
		
     return graph;
}

THANKS VERY MUCH;

I think you just need something like:

Code: Select all

XYPlot plot = (XYPlot) graph.getPlot();
NumberAxis rangeAxis = plot.getRangeAxis();
rangeAxis.setInverted(true);

Ok, but This change the X axis, no? How can I change the Y Axis ??

I have solved this:

Code: Select all

XYPlot plot = (XYPlot) chart.getPlot();
NumberAxis rangeAxis = (NumberAxis) plot.getDomainAxis();
rangeAxis.setInverted(true);

Thanks

Add a line:

Code: Select all

developer.setConfused(true);

(sorry I could not resist)
