Custom levels in Contour Chart don't work!!

[GFoundries]

Hello,

For all the issues mentioned below, I have provided the sample code I used.

• 1) ContourLevel creation issue:
  When I add data to contour charts using the add(double[] X, double[] Y, double[] Z) method and calling the setAutomaticLevels(true), setNumLevels(7) and createAutoLevels() methods to populate the levels, always considers the Y data to create levels not Z. Any specific reason why it does this way ?
  
  2) Contour custom level issue:
  • a) After I get all the ContourLevels by calling the createAutoLevels() and when I try to modify the individual levels by calling
    series.getLevels().getLevel(0).setUpToValue(2);
    to create my custom levels, it never reflects in the TeeChart ! Is this a bug or intentional ?
    b) Also I tried creating ContourLevels object and 7 ContourLevel objects for all the 7 levels I needed and added them to the series. It never takes this into account.
    It still creates it own levels in the chart.
    c) I tried using ContourLevelResolver too but it never gets a call back to the getLevel() method where I am setting my custom levels.

I tried doing all this by modifying the LevelsDemo code as per my need. In the ContourDemo class also, when ever I try to add any data using the add(double[], double[], double[]) method, I don't see any output for any data except for the one given in demo.

An early response is highly appreciated.

Thanks,
Gunjan

In ContourDemo, I have overridden the initComponents() method based on my requirement.

Code: Select all

 protected void initComponents() {
        super.initComponents();

        // First we add XYZ points to the Contour series...
        contourSeries = new com.steema.teechart.styles.Contour(chart1.getChart());

double[] X = {-2.54, -2.6232,-2.648,-2.6396,-2.6798, -2.6162, -2.6292, -2.622,-2.6556,-2.626,-2.648,-2.5866,-2.669,2.6088,-2.6788,-2.6266,-2.6486,-2.5492,-2.623};
double[] Y = {104.82,105.44,106.18,105.44,105.92,104.82,104.78,105.48,105.48,105.12,105.4,104.92,105.58,105.02,104.76, 105.24,105.62,105.36,105.1};
double[] Z = {3.563115488,2.873769024,2.784243509,2.560429722,2.452999105,3.464637422,2.882721576,3.22291, 3.124440466,3.321396598,3.491495076,3.965980304,3.314867763,3.18084346,3.368477484,3.082558971,3.368477484,3.600786276,3.63652609};

      contourSeries.add(X,Z,Y); // Had to give Z first so that it calculates level  based on Z not Y !!

      createCustomLevels(contourSeries);

      //setCustomLevels(); Tried this one too but doesn't work

     // We specify the Y levels position to the "middle"
        contourSeries.setYPosition((contourSeries.getYValues().getMaximum()+ contourSeries.getYValues().getMinimum() )/2.0);

       view2DButton = new JCheckBox("2D");
        showWallsButton = new JCheckBox("Show Walls");
        showWallsButton.setSelected(true);
        colorEachButton = new JCheckBox("Color Each Level");
        colorEachButton.setSelected(true);
        posLevelButton = new JCheckBox("Levels at Y");
        surfaceButton = new JCheckBox("Surface");

        levelSlider = new JSlider(JSlider.VERTICAL, 0, 1000, 50);
        levelSlider.setValue((int)(1000-Math.round(contourSeries.getYPosition())));

}

private void createCustomLevels(Contour contourSeries)
{
   ContourLevels levels = new ContourLevels();
        ContourLevel level1 = new ContourLevel(contourSeries);
        level1.setColor(Color.red);
        level1.setUpToValue(2.0);
        levels.add(level1);
        
        ContourLevel level2 = new ContourLevel(contourSeries);
        level2.setColor(Color.YELLOW);
        level2.setUpToValue(2.667);
        levels.add(level2);
        
        ContourLevel level3 = new ContourLevel(contourSeries);
        level3.setColor(Color.GREEN);
        level3.setUpToValue(3.333);
        levels.add(level3);
        
        ContourLevel level4 = new ContourLevel(contourSeries);
        level4.setColor(Color.BLUE);
        level4.setUpToValue(4.0);
        levels.add(level4);
        
        ContourLevel level5 = new ContourLevel(contourSeries);
        level5.setColor(Color.CYAN);
        level5.setUpToValue(4.667);
        levels.add(level5);
        
        ContourLevel level6 = new ContourLevel(contourSeries);
        level6.setColor(Color.PINK);
        level6.setUpToValue(5.333);
        levels.add(level6);
        
        ContourLevel level7 = new ContourLevel(contourSeries);
        level7.setColor(Color.BLACK);
        level7.setUpToValue(6.0);
        levels.add(level7);
        
        contourSeries.setNumLevels(7);
        contourSeries.setLevels(levels);

}


 private void setCustomLevels() {
        contourSeries.setNumLevels(7);
        contourSeries.createAutoLevels();
        contourSeries.getLevels().getLevel(0).setUpToValue(2.0);
        contourSeries.getLevels().getLevel(1).setUpToValue(2.667);
        contourSeries.getLevels().getLevel(2).setUpToValue(3.0);
        contourSeries.getLevels().getLevel(3).setUpToValue(3.333);
        contourSeries.getLevels().getLevel(4).setUpToValue(4.0);
        contourSeries.getLevels().getLevel(5).setUpToValue(4.667);
        contourSeries.getLevels().getLevel(6).setUpToValue(6.0);

    }

Hi Gunjan,

1) ContourLevel creation issue:
When I add data to contour charts using the add(double[] X, double[] Y, double[] Z) method and calling the setAutomaticLevels(true), setNumLevels(7) and createAutoLevels() methods to populate the levels, always considers the Y data to create levels not Z. Any specific reason why it does this way ?

I think here is happening the same as discussed here, isn't it?

2) Contour custom level issue:

a) After I get all the ContourLevels by calling the createAutoLevels() and when I try to modify the individual levels by calling
series.getLevels().getLevel(0).setUpToValue(2);
to create my custom levels, it never reflects in the TeeChart ! Is this a bug or intentional ?
b) Also I tried creating ContourLevels object and 7 ContourLevel objects for all the 7 levels I needed and added them to the series. It never takes this into account.
It still creates it own levels in the chart.
c) I tried using ContourLevelResolver too but it never gets a call back to the getLevel() method where I am setting my custom levels.

The following seems to work as expected, can't you see different levels than the default?

Code: Select all

        tChart1.getAspect().setView3D(false);

        tChart1.getSeries().clear();
        com.steema.teechart.styles.Contour contour = new com.steema.teechart.styles.Contour(tChart1.getChart());
        contour.fillSampleValues();

        com.steema.teechart.styles.ContourLevels levels = new com.steema.teechart.styles.ContourLevels();
        com.steema.teechart.styles.ContourLevel level1 = new com.steema.teechart.styles.ContourLevel(contour);
        level1.setColor(Color.RED);
        level1.setUpToValue(0.1);
        levels.add(level1);
        
        com.steema.teechart.styles.ContourLevel level2 = new com.steema.teechart.styles.ContourLevel(contour);
        level2.setColor(Color.YELLOW);
        level2.setUpToValue(0.2);
        levels.add(level2);

        com.steema.teechart.styles.ContourLevel level3 = new com.steema.teechart.styles.ContourLevel(contour);
        level3.setColor(Color.GREEN);
        level3.setUpToValue(0.3);
        levels.add(level3);

        com.steema.teechart.styles.ContourLevel level4 = new com.steema.teechart.styles.ContourLevel(contour);
        level4.setColor(Color.BLUE);
        level4.setUpToValue(0.4);
        levels.add(level4);

        com.steema.teechart.styles.ContourLevel level5 = new com.steema.teechart.styles.ContourLevel(contour);
        level5.setColor(Color.CYAN);
        level5.setUpToValue(0.5);
        levels.add(level5);

        com.steema.teechart.styles.ContourLevel level6 = new com.steema.teechart.styles.ContourLevel(contour);
        level6.setColor(Color.PINK);
        level6.setUpToValue(0.6);
        levels.add(level6);

        com.steema.teechart.styles.ContourLevel level7 = new com.steema.teechart.styles.ContourLevel(contour);
        level7.setColor(Color.BLACK);
        level7.setUpToValue(0.7);
        levels.add(level7);

        contour.setNumLevels(7);
        contour.setLevels(levels);

Hi Yeray,

For the point 2:

The following seems to work as expected, can't you see different levels than the default?

What I meant was if you try to modify the setUpToValue() to some other value, it doesn't reflect in the legend. The levels still show the same set of values always.
I had tried the LevelsDemo.java and changed the setCustomLevels() method with the sample code I provided in this topic. No matter what ever you provide in the method, it always gives you the same values for no of levels = 7 (Please check the image)

Thanks,
Gunjan

Hi Gunjan,

You are right. It seems that the changes made to a level (through the editor or via setUpToValue method) aren't reflected at the legend.
I've added it to the defect list to be fixed in future releases (TJ71015008).
