BoxAndWhisker bug

grzegorz.majer · Post by **grzegorz.majer** » Wed Sep 03, 2003 6:13 pm

BoxAndWhisker in BoxAndWhiskerDemo plot works correctly, but values are near 0. The problem is that the plot has incorrect Y scale when I have higher values and when I use

Code: Select all

valueAxis.setAutoRangeIncludesZero(false);

You can check it in BoxAndWhiskerDemo.

Are you using 0.9.11 or the latest CVS code? There have been quite a few changes made to the box-and-whisker plots for the next release (0.9.12).

I'm using the latest CVS code.

Hi grzegorz.majer

I'm just back from a vacation, so I will look at the problem in the next day or so. Please send me a sample of the values you used.

I've got the latest version from CVS and it works correctly.

Thanks for your help.

In BoxAndWhiskerRenderer.java is:

Code: Select all

   public void drawVerticalItem(Graphics2D g2, 
                                 Rectangle2D dataArea,
                                 CategoryPlot plot, 
                                 CategoryAxis domainAxis, 
                                 ValueAxis rangeAxis,
                                 CategoryDataset dataset, 
                                 int row, 
                                 int column) {

        BoxAndWhiskerCategoryDataset bawDataset = (DefaultBoxAndWhiskerCategoryDataset) dataset;

but should be

Code: Select all

        BoxAndWhiskerCategoryDataset bawDataset = (BoxAndWhiskerCategoryDataset) dataset;

I've found a new problem. When there is only one series a BoxAndWhiskerRenderer draws chart which looks like this:

Many thanks for your helpful remarks.

Yes, there was originally some overly complex code to allow the width of the box to be limited. The width of the box also determines the with of the other components.

The actual bug was in fact that the setBoxWidth method was not working.

I have fixed it by changing the followning code in BoxAndWhiskerRenderer:

public void initialise(Graphics2D g2,
Rectangle2D dataArea,
CategoryPlot plot,
Integer index,
ChartRenderingInfo info) {

super.initialise(g2, dataArea, plot, index, info);

ValueAxis rangeAxis = getRangeAxis(plot, index);

// calculate the box width
CategoryAxis domainAxis = getDomainAxis(plot, index);

CategoryDataset dataset = getDataset(plot, index);
if (dataset != null && this.getBoxWidth() == 0.0) {

If you cut and paste don't forget to remove the color tags (;

You can then use the setBoxWidth method, eg:

BoxAndWhiskerRenderer renderer = new BoxAndWhiskerRenderer();
renderer.setBoxWidth(8.0);

The Category title at x-axis and the bar do not lineup well. For a single series, while the bar (data series) is to the left of the chart but the title for the bar is in the middle of the x-axis. I wish I could put the chart here, but I couldn't paste it. Is there a fix for this?

Thanks.[/img]

Yes. I've noted this, but as yet I don't have a fix. I will work on it over the next few days.

David,

Did you get a chance to take a look at this bug? If you do not time, could you please point out where I should look at if I want to modify the code myself?

Thank you very much!

I suspect the problem is not actually in the code I wrote, so I can't simply point you in the correct direction. I will try to look at it tonight (about 12 hours time) - if I don't succeed, I will post a reply telling where I looked.

Sorry for the delay.
