StackedBarChart3D problem with y-axis (number axis)

[Ranjith]

Hi All,

I have to display a status chart using StackedBarChart3D.
I am getting data like this from DB:

Month Assigned Unassigned GateKeeper InProgress Completed
-------------------------------------------------------------------------------------
Aug 0 0 0 0 0
Sep 0 0 0 0 0
Oct 99 0 53 36 3
Nov 0 0 0 0 0
etc...

I am displaying this data using StackedBarChart3D.
the code is:

Code: Select all

LsfuSummary status = (LsfuSummary)request.getAttribute("monthlystatus"); // this atttribute consists the data shown above

  final String[] strMonths = new String[12];
  final int[] strUnassigned=new int[12];
  final int[] strGateKeeper=new int[12];
  final int[] strAssigned=new int[12];
  final int[] strInProgress=new int[12];
  final int[] strCompleted=new int[12];
  final int[] strAllStatus=new int[12];
  
  ProgramSummaryEntry pse=null;
  for(int i=0;i<status.size();i++)
  {
       pse=(ProgramSummaryEntry)status.get(i);
       strMonths[i]=pse.getName();
       strUnassigned[i]=pse.getUnAssigned();
       strGateKeeper[i]=pse.getWithGk();
       strAssigned[i]=pse.getAssigned();
       strInProgress[i]=pse.getInProgress();
       strCompleted[i]=pse.getCompleted();
       strAllStatus[i]=pse.getTotal();
  }

DatasetProducer categoryData = new DatasetProducer() {
   public Object produceDataset(Map params) {
	
	String[] categories = strMonths;
	final String[] seriesNames = { "Unassigned", "GateKeeper", "Assigned", "In Progress", "Completed" };
	final Integer[][] startValues = new Integer[seriesNames.length][categories.length];
	final Integer[][] endValues = new Integer[seriesNames.length][categories.length];
			
     for (int i = 0; i < categories.length; i++) 
    {
        int intTmpVal=0;
        for (int series = 0; series < seriesNames.length; series++) 
       {
	if(series==0)
	{
		startValues[series][i] = new Integer(0);
		endValues[series][i] = new Integer(strUnassigned[i]);
						intTmpVal=strUnassigned[i];
	}
	else if(series==1)
	{
							startValues[series][i] =new Integer(intTmpVal);
	endValues[series][i] = new Integer(intTmpVal+strGateKeeper[i]);
						intTmpVal+=strGateKeeper[i];
	} etc.....
      }
  }
DefaultIntervalCategoryDataset ds =new DefaultIntervalCategoryDataset(seriesNames, categories, startValues, endValues);								
return ds;
}

But Y-axis shows 700 always instead of 191(total of all months)
Can anybody help me out of this? Thanks in advance

In your sourcecode I see only specific code and very little jFreeChart. Try to simplify and to reduce your code and post a working example.

Yes, without a runnable demo of the problem there isn't much we can do to help.

Hi David/ Angel,

Thanks for the prompt response. I got a solution.
I am using intTmpVal for y-axis values. It is getting double addition.

I have been asked to do work with other charts, but i have insisted on JFreeChart. It is a good API.

I am asking n suggesting everybody to use JFreeChart. Infact, we are planning to buy Developer's guide.

Can we create Organizational charts (like tree-node) using JFreeCharts?

Thanks. Income from selling the JFreeChart Developer Guide has allowed me to keep working on the project for so long now, so your support is appreciated.

No, JFreeChart can't help with that. But JGraph might help:
