CircularGauge - PackageMistake?

Hello all,
I have the following problem: I wanted to set up an circularGauge with the following code (out of Forum):
Code: Select all
Steema.TeeChart.Styles.CircularGauge circularGauge1 = new Steema.TeeChart.Styles.CircularGauge(tChart1.Chart);
circularGauge1.Frame.Visible = false;
circularGauge1.FaceBrush.Visible = false;
circularGauge1.DisplayTotalAngle = 180;
circularGauge1.TotalAngle = 180;
circularGauge1.Value = 200;
circularGauge1.Ticks.Visible = false;
circularGauge1.Minimum = 0;
circularGauge1.Maximum = 1000;
circularGauge1.Axis.AxisPen.Visible = false;
circularGauge1.Axis.Increment = 500;
circularGauge1.RedLine.Visible = false;
circularGauge1.GreenLineStartValue = 0;
circularGauge1.GreenLineEndValue = 1000;
circularGauge1.GreenLine.Gradient.Direction = Steema.TeeChart.Drawing.GradientDirection.LeftRight;
circularGauge1.GreenLine.Gradient.UseMiddle = true;
circularGauge1.GreenLine.Gradient.StartColor = Color.Orange;
circularGauge1.GreenLine.Gradient.MiddleColor = Color.Yellow;
circularGauge1.GreenLine.Gradient.EndColor = Color.Green;
circularGauge1.GreenLine.Pen.Visible = false;
My Code is like this:
Code: Select all
TChart chart;
chart = new TChart(this.getActivity());
Series series = null;
series = Series.createNewSeries(chart.getChart(), CircularGauge.class, null);
chart.Frame // ...... Frame is not possible to use - why is it?
chart.FaceBrush //...... FaceBrush is not possible to use...
// [...] the same on each line if I want to use it like on top
I can't get CircularGauge".Frame" ".FaceBrush" etc...
Can you tell me what's my mistake and give me some sample code for my declaration?
Is there a mistake in Import of TeeChart?
Thank you very much.

Hello,
Note a difference between C# and Java is that Java we use getters and setters to retrieve and set properties respectively. Ie we call getFrame() to access the Frame, and we call setVisible(false) to change the visibility of an object.
Also note in the first code you posted you are accessing the properties from circularGauge1, that is an instance of the Steema.TeeChart.Styles.CircularGauge class.
However, in the Java version you are trying to access the properties from chart, that is an instance of the TChart class. You need an instance of the CircularGauge class. Ie:
Code: Select all
TChart chart;
chart = new TChart(this.getActivity());
CircularGauge series = null;
series = (CircularGauge)Series.createNewSeries(chart.getChart(), CircularGauge.class, null);
series.getFrame().setVisible(false);
series.getFaceBrush().setVisible(false);
// [...]

Hello Yeray,
thank you for your support. I have another question. I want to have my Circular Gauge to look like this:
That means I want to have the two thresholds. The lower Threshold to define where the first colour ends and second begins. An upper threshold to define where the second colour ends an the third begins.
In TeeChart I only find two "Lines" : "GreenLine" and "RedLine". Is it possible to have an third "Line"?.
As next I want to have an big number (value of the gauge) on the bottom of the gauge.
What's the Code for this? I only find the following code to get the value. But there is something like a frame behind this. I only want a big number as value on bottom.
Code: Select all
series.getNumericGauge().setVisible(true);
series.getNumericGauge().getFrame().setVisible(false);
series.getNumericGauge().getBrush().setVisible(false);
series.getNumericGauge().getFaceBrush().setVisible(false);
series.getNumericGauge().getMarks().setVisible(false);
// series.setAutoValueNumericGauge(true);
thank you for your support.

This is a feature request already present in the public tracker

Have you tried with an Annotation tool? Ie:
Code: Select all
Annotation annot1 = new Annotation(tChart1.getChart());
annot1.setText("my annotation");
annot1.getShape().setCustomPosition(true);
annot1.getShape().setLeft(100);
annot1.getShape().setTop(100);

Thanks for reply.
I did it now like this. It's still a frame around it, but I think it's okay:
Code: Select all
series3.getNumericGauge().getValueMarker().getShape().setTransparent(true);
series3.getNumericGauge().getValueMarker().getShape().getFont().setBold(true);
series3.getNumericGauge().getValueMarker().getShape().getFont().setSize(20);
I have another question. I want to have percentage values around the circular gauge.
2 -> 2%, 4 -> 4%....
The value on the bottom (inside getNumericGauge() - full value of CircularGauge) should be with percentage, too.
How can I do this?
Thank you for your support Yeray!

Great! You are right, I missed it!

For the labels, you could use the AxisLabelResolver. Ie:
Code: Select all
tChart1.setAxisLabelResolver(new AxisLabelAdapter() {
@Override
public String getLabel(Axis axis, ISeries s, int valueIndex,
String labelText) {
return labelText + "%";
}
});

For the ValueMarker below, I'm afraid there's no option to customize the text. Note the drawHand method in NumericGauge.java does it as follows:
Code: Select all
getValueMarker().setText(Double.toString(truncate(getValue())));
getValueMarker().drawText((Graphics3D) g);
I'll open a new ticket in the public tracker to try implement an event or some other feature to support this.

Hello Yeray,
I have another question about the CircularGauge.
Now I know, that it is only possible to have one threshold (Change between "GreenLine" and "RedLine").
I want to label this threshold and give it a name.
That means: Change between GreenLine and Redline is at value "5". So at value 5 I want to write something on the CircularGauge.
Is that possible?
Thank you very much for your support, Yeray!

Try with the Annotation tool. I suggested you to use it
above, when I missed the NumericGauge embedded into the CircularGauge.
