How to calculate proper aspect for 3d and clicked

[AergoUser]

Hi, I am having a challenge getting the proper aspect from the mouse click to recognize the chart in the proper 3d aspect. here is how I am doing it;

Code: Select all

     @Override
      public void seriesClicked(SeriesMouseEvent sme) {		
          int x = sme.getPoint().x;
	       int y = sme.getPoint().y;
	       int index = sme.getSeries().clicked(x, y);
	       Series series = (Series)sme.getSource();
	       SeriesXYPoint point = series.getPoint(index);
      }

If I turn off 3d everything is fine and I get back the proper index of my points properly but one I turn on 3d it stops. Especially in a PIE. It seems like I should be doing a calcToPos or something but I can't find how to do it based JUST off of the mouse position. There is a post here using a crosshair cursor but I can't find the relation of how to do it without a CursorTool. Is that my problem? Do I need a cursor tool?

Shouldn't the chart internally know its own aspect and do the calculations itself? Does this break the laws of responsibility?

Hi AergoUser,

Yes, I think clicked method should be enhanced for pie series. I've added this defect (TJ71014362) to the bug list to be fixed for future releases.

This is also a problem on the other chart types also. If its a bar only the front face of the bar is recognized, not any side that is a 3-D look and a click and the 3D line, I suppose I'm not sure how exactly that should work.

Hi ZooX,

If its a bar only the front face of the bar is recognized, not any side that is a 3-D look

Yes, this is not implemented and is already in the wish-list to be considered for inclusion in future releases.

and a click and the 3D line

Code below works fine for me here. However, I've seen it throws an exception in some ocasions so I'll add it to the defect list to be enhanced for future releases.

Chart initialization:

Code: Select all

    private void initChart() { 
        
        // tChart1.getAspect().setView3D(false);

        Line series = new Line(tChart1.getChart());
        series.fillSampleValues();
        series.addSeriesMouseListener(new seriesMouseAdapter());        
    }

Events implementation:

Code: Select all

class seriesMouseAdapter extends SeriesMouseAdapter
{
    @Override
    public void seriesClicked(SeriesMouseEvent sme) {
        int x = sme.getPoint().x;
        int y = sme.getPoint().y;
        int index = sme.getSeries().clicked(x, y);
        Series series = (Series)sme.getSource();
        
        series.chart.getHeader().setText(Integer.toString(index));
    }

    @Override
    public void seriesEntered(SeriesMouseEvent arg0) {
        super.seriesEntered(arg0);
    }

    @Override
    public void seriesExited(SeriesMouseEvent arg0) {
     super.seriesExited(arg0);
    }
}

Thanks, do you guys have a date for the next release that your shooting for?

Hi Zoox,

IIRC there's a new release scheduled before the end of the year but can't provide an estimate date for now. I recommend you to be aware at this forum or subscribe to our RSS news feed for new release announcements.

[ZooX]

Ok, we are past the end of the year (2009), when do you anticipate the next release?

Hi Brian,

We have modifications pending to put into a maintenance release build. However those do not include a modification for TJ71014362 as we were unable to reproduce the problem, the example functioned correctly in 2D and 3D. It may be that one of the outwardly non-related fixes has affected this functionality too. We will attempt to make a new release available within the next week.

Hi Brian,

The version has been released now:

I just downloaded and updated to the new version and this is NOT working. I am getting the same result.

I believe the core problem is that the 3d aspect is not being taking into account on the clicks. If I have a 3d bar, the very front face is fine, this is the 2d part of the image but if I click on ANY of the sides that make up the 3d part of it (meaning the ones that extend backwards) If I click any part of those sides it does not register as that component being clicked. Same story with Pie and Line

Hi,

I'm able to reproduce the problem too so, or another change has broken it again, or we made a mistake when we checked it the 14th January 2010.
I've reopened the bug ticket TJ71014362. Excuse us for the confusion generated.

[ZooX]

Do you guys have an ETA on the release that will include this fix?

Hi Brian,

I'm sorry but I'm not able to provide an estimate date for now as the issue hasn't been fixed yet. I recommend you to be aware at this forum or subscribe to our RSS news feed for new release announcements and what's fixed on them.

[ZooX]

Any news on this? I haven't seen anything in the feeds or did I miss something?

If you can even tell me a workaround if I subclass one of you classes because I think I am going to be forced to choose another chart provider and have to wire up all of my logic to a new chart if you don't have this any time soon.

Hi Brian,

We have no status change logged for this issue. We'll check it and get back to this thread before the middle of next week.
