How to use SymbolicAxis? - Urgent

guest123 · Post by **guest123** » Thu Sep 01, 2005 12:08 am

Hi,
I am trying to use SymbolicAxis to replace x-axis labels from double to string. It is not replacing existing labels.
Here is code segment.

Code: Select all

// Create SymbolicAxis
String[] str = new String[]{"jan", "feb", "mar","apr", "may", "jun","jul", "aug", "sep","oct", "nov", "dec"};

org.jfree.chart.axis.SymbolicAxis newAxis = new org.jfree.chart.axis.SymbolicAxis("Month",str); 

newAxis.setSymbolicGridLinesVisible(true);
newAxis.setTickLabelsVisible(true); 

// Create XYSeries 
XYSeries series = new XYSeries("Test Data"); 
		series.add(1, 10); 
		series.add(2, 20); 
		series.add(3, 40); 
		series.add(4, 50); 
		series.add(5, 45); 
		series.add(6, 41); 
		series.add(7, 54); 
		series.add(8, 32); 
		series.add(9, 35); 
		series.add(10,39); 
		series.add(11,41); 
		series.add(12,44); 		


// Create XYBar
		org.jfree.chart.renderer.xy.XYBarRenderer xyBarRenderer1 = new org.jfree.chart.renderer.xy.XYBarRenderer(0.04); 	
	
		XYDataset data = new XYSeriesCollection(series); 


		ValueAxis numberaxis1 = new NumberAxis("Value"); 

// Create Plot
		final XYPlot p = new XYPlot(data, newAxis, numberaxis1, xyBarRenderer1);

Can someone please help me understand what is missing here?
Thanks

The SymbolicAxis was contributed by another developer who wrote it for a very specific purpose. It replaces integers in the sequence (0, 1, 2, 3 ...) with the supplied labels. So the first problem I notice is that your number sequence is (1, 2, 3, 4 ...).

David,
I made change to the data and it starts with zero but seems like it is not helping.

Code: Select all

		String[] str = new String[]{"jan", "feb", "mar","apr", "may", "jun","jul", "aug", "sep","oct", "nov", "dec"};

		System.out.println("Initializing Symbolic");

		org.jfree.chart.axis.SymbolicAxis newAxis = new org.jfree.chart.axis.SymbolicAxis("Month",str); 

		newAxis.setSymbolicGridLinesVisible(true);
		
		newAxis.setTickLabelsVisible(true); 


		
		XYSeries series = new XYSeries("Test Data"); 
		series.add(0, 1); 
		series.add(1, 10); 
		series.add(2, 20); 
		series.add(3, 40); 
		series.add(4, 50); 
		series.add(5, 45); 
		series.add(6, 41); 
		series.add(7, 54); 
		series.add(8, 32); 
		series.add(9, 35); 
		series.add(10,39); 
		series.add(11,41); 
//		series.add(12,44); 		// CHANGE I MADE


		org.jfree.chart.renderer.xy.XYBarRenderer xyBarRenderer1 = new org.jfree.chart.renderer.xy.XYBarRenderer(0.04); 	
	
		XYDataset data = new XYSeriesCollection(series); 


		ValueAxis numberaxis1 = new NumberAxis("Value"); 

		final XYPlot p = new XYPlot(data, newAxis, numberaxis1, xyBarRenderer1); 		
        return new JFreeChart("Symbolic axis", JFreeChart.DEFAULT_TITLE_FONT, p, true);

Any other suggestions? Help?
Thanks

what package do you use? SymbolicAxis has been renamed SymbolAxis in 1.0.0.rc1.

Thomas,
I am using jfreechart-1.0.0-rc1. I am not able to find SymbolAxis in this package. Any other place to get it?
Do you any working code that I can execute on my machine to see if it works?
Any other suggestions/help?
Thanks

hmm, what is it SymbolicAxis or SymbolAxis?

the following is a snippet of comment form SymbolAxis:

* 06-Jul-2005 : Renamed SymbolicAxis --> SymbolAxis, added equals() method,...

It's renamed for the next release - I did this while tidying up and documenting the class. I also removed the SymbolicTickUnit class, which isn't required.
