Hi Dmitry,

We are finding some problems in 3D that we are trying to solve but in 2D it seems to work fine:

Code: Select all

public void doMarks()
    {
        com.steema.teechart.styles.SeriesMarksPosition sMarkPos =
                new com.steema.teechart.styles.SeriesMarksPosition();

        chart1.repaint();

        sMarkPos.height = chart1.getGraphics3D().textHeight("H") + 2;
        int yDisp = sMarkPos.height + 5;

        int[] xPos = new int[pieSeries.getCount()];
        int[] yPos = new int[pieSeries.getCount()];
        for (int i = 0; i < pieSeries.getCount(); i++)
        {
            xPos[i] = pieSeries.getMarks().getPositions().getPosition(i).leftTop.x;
            yPos[i] = pieSeries.getMarks().getPositions().getPosition(i).getBounds().y;
        }

        for (int i = 0; i < pieSeries.getCount(); i++)
        {
          sMarkPos = new com.steema.teechart.styles.SeriesMarksPosition();
          sMarkPos.custom = true;
          sMarkPos.height = chart1.getGraphics3D().textHeight("H") + 2;

          if ((i>0) && (Math.abs(yPos[i] - yPos[i-1]) < yDisp)
                    && (Math.abs(xPos[i] - xPos[i-1]) <
                    chart1.getGraphics3D().textWidth(pieSeries.getMarkText(i-1))))
                  xPos[i] = xPos[i] + chart1.getGraphics3D().textWidth(pieSeries.getMarkText(i-1));

          sMarkPos.leftTop.setLocation(xPos[i],yPos[i]);
          sMarkPos.width = chart1.getGraphics3D().textWidth(pieSeries.getMarkText(i)) + 5;

          pieSeries.getMarks().getPositions().setPosition(i, sMarkPos);
        }

        chart1.repaint();
    }

Hi Dmitry,

Here you have a simple example of how you could move the marks. As you'll see, when this application is started, some marks overlap the others but clicking the button we calculate new positions moving them more to the right-bottom until there is enough space to draw them:

Code: Select all

    Pie pie1;

    private void initChart() {
        commander1.setChart(tChart1.getChart());
        
        tChart1.getAspect().setView3D(false);

        pie1 = new Pie(tChart1.getChart());

        pie1.add(300, "first");
        pie1.add(5, "second");
        pie1.add(2, "third");
        pie1.add(3, "fourth");
        pie1.add(4, "fifth");

        tChart1.getAspect().setOrthogonal(false);
        tChart1.getAspect().setElevation(280);
        tChart1.getAspect().setRotation(0);
    }

    public void doMarks()
    {
        Rectangle R1,R2;
        for (int i=0; i<pie1.getCount()-1; i++)
        {
            for (int j=0; j<pie1.getCount()-1; j++)
            {
                if (j!=i)
                {
                    com.steema.teechart.styles.SeriesMarksPosition mp1 = pie1.getMarks().getPositions().getPosition(i);
                    com.steema.teechart.styles.SeriesMarksPosition mp2 = pie1.getMarks().getPositions().getPosition(j);

                    R1 = mp1.getBounds();
                    R2 = mp2.getBounds();
                    while   (  (R1.getLeft() > R2.getLeft()
                            && R1.getLeft() < R2.getRight())
                            || (R1.getRight() > R2.getLeft()
                            && R1.getRight() < R2.getRight())
                            || (R1.getTop() > R2.getBottom()
                            && R1.getTop() < R2.getTop())
                            || (R1.getBottom() > R2.getTop()
                            && R1.getBottom() < R2.getBottom()) )
                    {
                        mp1.custom = true;
                        mp1.leftTop.x = mp1.leftTop.x + 2;
                        mp1.leftTop.y = mp1.leftTop.y + 2;
                        mp1.arrowTo.x = mp1.leftTop.x + 2;
                        mp1.arrowTo.y = mp1.leftTop.y + 2;
                        R1 = mp1.getBounds();
                        R2 = mp2.getBounds();
                    }
                    tChart1.repaint();
                }
            }
        }
    }

    @Action
    public void ButtonClick() {
        doMarks();
    }
