Urgent need of help! How do I make this graph??

[cmaas]

I left a post earlier but I think I am just too much of a newbie to use the advice...I need a simple 3D bar chart that looks like the picture very soon...we have a deadline in 2 days. I bought the manual and have been searching through posts but haven't found the answer. I want to pass in a bunch of codes that are all related to a weight (i can do this in any way, as long as the chart will work)... i need the chart to look like this:



if anyone knows how to create this simple chart and can possibly give me an example that would be amazing.. thanks!

heres what it looks like...

Does anyone know the answer to this? I am in URGENT need of help!!

[javageek]

I also am having this problem..there must be some way to make a simple Bar Chart in JFree. Anyone?

[cmaas]

this has been up here for awhie and no one ahs responded...maybe its impossible? but if you can help that would be amazing
Thanks

Have you tried using:

ChartFactory.createBarChart3D(String title,
String categoryAxisLabel,
String valueAxisLabel,
CategoryDataset dataset,
PlotOrientation orientation,
boolean legend,
boolean tooltips,
boolean urls) {

???

Hey, thanks if you looked here but didn't know...but what i had to do was create a regular chart and then create my own CustomRenderer. Here is the code:

just the renderer:

private class CustomRenderer extends BarRenderer3D {

/** The colors. */
private Paint[] colors;

/**
* Creates a new renderer.
*
* @param colors the colors.
*/
public CustomRenderer(Paint[] colors) {
this.colors = colors;
}

/**
* Returns the paint for an item. Overrides the default behaviour inherited from
* AbstractSeriesRenderer.
*
* @param row the series.
* @param column the category.
*
* @return The item color.
*/
public Paint getItemPaint(int row, int column) {
return this.colors[column % this.colors.length];
}
}





the whole code:

/**
* Calculates the supply short tons for the selected supply center.
*/
public class SCShortTonBarChartByCommodityCode extends Action {


/**
*
*
*/
public SCShortTonBarChartByCommodityCode() {
putValue(Action.NAME,"Inventory Short Tons by CC");
putValue(Action.LONG_DESCRIPTION, "Create a Bar Graph for Inventory Short Tons by CC");
}

/**
* Overriding classes implement this function that will perform an
* action on the passed in class.
*
* @param object
* @return
*/
public void performAction(Bean bean) throws Exception {
if (bean instanceof SupplyCenter) {
SCBarChart chart = new SCBarChart((SupplyCenter)bean);
chart.setSize(500, 270);
chart.setVisible(true, bean.getDomain().getDomainFrame());
}
}

/*
*
*/
private class SCBarChart extends ManagedPanel {
public SCBarChart(SupplyCenter sc) {
super(sc.getDomain());
CategoryDataset dataset = createDataset(sc);
JFreeChart chart = createChart(dataset);
ChartPanel chartPanel = new ChartPanel(chart, false);
//chartPanel.setPreferredSize(new Dimension(500, 270));
//setMainComponent(new JScrollPane(chartPanel));
setMainComponent(chartPanel);
}

private CategoryDataset createDataset(SupplyCenter sc) {
DefaultKeyedValues2DDataset dataset = new DefaultKeyedValues2DDataset();
String possibleValues = "234ABCDEFGHJKMRSTUVY";
ArrayList<String> codes = new ArrayList<String>();
for(int i = 0; i < possibleValues.length(); i++) {
codes.add(i, possibleValues.substring(i, (i + 1)));
}

List<Object[]> l = sc.getWeightByCommodityCode();
Iterator iter = l.iterator();
Object[] codeWeight = (Object[]) iter.next();
for (Iterator iterator = codes.iterator(); iterator.hasNext();) {
double tons;
String code = (String) iterator.next();
String compareValue = (String) codeWeight[0];
if (code.equals(compareValue)) {
tons = Double.parseDouble(codeWeight[1].toString());
if (iter.hasNext()) {
codeWeight = (Object[]) iter.next();
}
}
else {
tons = 0;
}

dataset.addValue(tons, "", code);
}
return dataset;
}

*
