Android CircularGauge Logarithmic axis

[Eliana]

Hi,

I’m using Teechart Java Android source code v3.2013.1219.
I’m using the following code to set a logarithmic axis on the circular gauge but it still gives me a linear scale.

Code: Select all

circularGauge = new CircularGauge(chart.getChart());

circularGauge.setMinimum(0);
circularGauge.setMaximum(512);

circularGauge.getVertAxis().setLogarithmic(true);
circularGauge.getVertAxis().setLogarithmicBase(2.0);
circularGauge.getVertAxis().setIncrement(1);

Do I need to use something else to enable the logarithmic axis or the CircularGauge does not support such functionality?

Thank you in advance.

Thanks for the feedback.
Btw, do bars and line charts support logarithmic axis?

Hello,

Yes, take a look at the following code:

Code: Select all

        Bar bar1 = new Bar(tChart1.getChart());
        bar1.fillSampleValues();
        try {
            tChart1.getAxes().getLeft().setLogarithmic(true);
        } catch (ChartException ex) {
            Logger.getLogger(ChartJFrame.class.getName()).log(Level.SEVERE, null, ex);
        }

This is how it looks the chart after running the above:
