Hi,

I have created application which use this Bar chart.To show issue to you I have also created Demo application and Chart related snippet is as follow:

Code: Select all

        TChart chart = new TChart(this);
        LinearLayout linearLayout = (LinearLayout)findViewById(R.id.linearLayout);
        Bar bar = new Bar(chart.getChart());

        chart.getAspect().setView3D(false);
        
        StringList labelsList = new StringList(1);
        labelsList.add(0,"40");

        bar.getMarks().setVisible(true);
        bar.setMarksOnBar(true);
        bar.add(0,40,"40");
        bar.setLabels(labelsList);
        
        chart.getAxes().getBottom().getCustomLabels().clear();
        chart.getAxes().getBottom().getCustomLabels().add(0.0, "40");
        
        linearLayout.addView(chart);

Hi

You can set the Marks visible or invisible with the following function:

Code: Select all

bar.getMarks().setVisible(true);

And you could check if your series has one value or several with the getCount() function:

Code: Select all

bar.getMarks().setVisible(bar.getCount()==1);
