Hi,

In some cases Marks are not visible for CustomBar.

import javax.swing.JFrame;
import javax.swing.JPanel;

import com.steema.teechart.TChart;
import com.steema.teechart.styles.Bar;
import com.steema.teechart.styles.CustomBar;

public class Test {

   public static void main(String[] args) {
      JFrame frame = new JFrame();
      JPanel panel = new JPanel();
      panel.setSize(600, 600);
      TChart chart = new TChart();
      chart.getAxes().getLeft().getTitle().setText("Help Needed");
      chart.getAxes().getLeft().setMinMax(0,50);
      panel.add(chart);
      CustomBar pareto = new Bar(chart.getChart());
      pareto.add(50, "a");
      pareto.add(50, "b");
      pareto.add(50, "c");
      chart.getChart().getTitle().setText("");
      frame.add(panel);
      frame.setSize(600, 600);
      frame.setVisible(true);
   }
}

In this code I am setting left axis min and max to 0 and 50 respectively.
If you run the code then you can see that Marks are not visible.
This is a special case where the chart title is empty and axis max == max value for a CustomBar. Is there anyway I could display Marks on the bar itself? Or how can I make it visible at least?

Thanks,
Varun

Hi Varun,

Yes, this is because of the settings you used for left axis scale.

An option is setting marks ArrowLength to zero or a negative value, for example:

Code: Select all

        pareto.getMarks().setArrowLength(-5);

Another one is setting left axis maximum offset, for example:

Code: Select all

        chart.getAxes().getLeft().setMaximumOffset(50);

Last option I can think of would be setting custom marks positions as shown on this thread. This is a TeeChart for .NET thread but the same applies to the Java version.

Hope this helps!
