TeeChart for android Area issues

[jesus.navarro]

Hi, I’m using Tee Chart for Android and I’ve got some troubles using Area Chart.
The first is that the Area chart is only painting the area between the two last points on the chart.
The Second is that the chart does not start in the left side of the layout, there is a weird unused white space before the chart starts. My guess is that the left axis lifts that space but I don’t know how to delete it.



Heare is the code:

I'm using TeeChart Java v1 for Android

I really apreciate your help.

Hi Jesus,

I see you have hidden the Walls:

Code: Select all

         chart.getWalls().setVisible(false);

If I comment the line above, with this code on my Activity onCreate method, I get the chart below:

Code: Select all

		LinearLayout group = (LinearLayout) findViewById(R.id.chart_layout);

		double[] xvals = {5, 10, 15, 20};
		List<double[]> xvalues = new ArrayList<double[]>();
		xvalues.add(xvals);
		
		double[] yvals = {6000, 8000, 10000, 12000};
		List<double[]> yvalues = new ArrayList<double[]>();
		yvalues.add(yvals);
		
		GraficaLineas grafica = new GraficaLineas(xvalues, yvalues, this, "Enero", 2);
		TChart tChart1 = grafica.getGrafica(); 
		group.addView(tChart1);

Then, it seems the space on the left is actually the space for the left axis labels, that you have moved to the right with:

Code: Select all

			chart.getAxes().getLeft().setRelativePosition(100);

But you could use the right axis instead:

Code: Select all

			chart.getSeries(0).setVerticalAxis(VerticalAxis.RIGHT);

And set the right axis instead of the left axis:

Code: Select all

	void axesStyle(double tamañom, double tamañm) {
		if (call == 1 || call == 3) {
			chart.getAxes().getRight().setAutomatic(false);
			chart.getAxes().getRight().setStartPosition(0);
			chart.getAxes().getRight().setIncrement(1);
			chart.getAxes().getRight().setMaximum(tamañom + 1);
			chart.getAxes().getRight().getAxisPen().setVisible(false);
			chart.getAxes().getRight().getGrid().setVisible(false);
			//chart.getAxes().getRight().setRelativePosition(100);
		}
		if (call == 2) {
			chart.getAxes().getRight().setAutomatic(false);
			chart.getAxes().getRight().setMaximum(tamañom + 500);
			if (tamañom > 300) {
				chart.getAxes().getRight().setMinimum(tamañm - 300);
			} else {
				chart.getAxes().getRight().setMinimum(tamañm);
			}
			chart.getAxes().getRight().getLabels().setValueFormat("$");
			chart.getAxes().getRight().getAxisPen().setVisible(false);
			chart.getAxes().getRight().getGrid().setVisible(false);
			//chart.getAxes().getLeft().setRelativePosition(100);
		}
	}

Then, hiding the walls again I get this:

Is that what you wanted?
You can also try playing with the Panel Margins, setting negative values.

Hi Yeray,

About the Area Brush, I've tried

Code: Select all

chart.getWalls().setVisible(true);

and it's still not working.

I've seen that you inserted a layout inside the class that I've posted, but I'm ussing it ass an object. I have a class A that calls this class, it's something like this:
code:

Code: Select all

RelativeLayout layout1 = (RelativeLayout)vista.findViewById(R.id.layout1);
RelativeLayout layout2 = (RelativeLayout)vista.findViewById(R.id.layout2);
private TChart gv_1 = null;
private TChart gv_2 = null;
gv_1 = new GraficaLineas(x1	, y1, getActivity(), mesg, 2).getGrafica();
gv_2 = new GraficaLineas(x2 , y2, getActivity(), mesg, 1).getGrafica();
layout1.removeAllViews();
layout2.removeAllViews();
layout1.addView(  gv_1);
layout2.addView( gv_2 );

And about the Axis, I've tried setting the right axis, but I need the ticks to be displayed after the labels and setting the right axis the ticks are displayed before the labels. Is there a way to set the order to display ticks and labels int right axis?.

Thanks for your help Yeray.

Hi Yeray,

About the Area Brush, I've tried

Code: Select all

chart.getWalls().setVisible(true);

and it's still not working.

Sorry, I haven't been able to reproduce the problem with the Area Brush. It seems to be correctly drawn for me here with v2012.0808. Is this one the version you are using?
Making the Walls visible was just to notice how the space on the left seems to be the same the axis labels have reserved.

And about the Axis, I've tried setting the right axis, but I need the ticks to be displayed after the labels and setting the right axis the ticks are displayed before the labels. Is there a way to set the order to display ticks and labels int right axis?.

I think the easier way to achieve this is to use a custom axis because only the regular axes (left, right, top, bottom) calculate and reserve the space the labels need to be drawn.
To do so, you could create and assign the custom axis before calling your axesStyle function:

Code: Select all

			Axis myAxis = new Axis();
			chart.getAxes().getCustom().add(myAxis);
			series.setCustomVertAxis(myAxis);
			
			axesStyle(series.getMaxYValue(), series.getMinYValue());

And then, the axesStyle function could be slightly different, to configure this custom axis instead of the default left or right one:

Code: Select all

	void axesStyle(double tamañom, double tamañm) {
		Axis myAxis = series.getCustomVertAxis();
		if (call == 1 || call == 3) {
			myAxis.setAutomatic(false);
			myAxis.setStartPosition(0);
			myAxis.setIncrement(1);
			myAxis.setMaximum(tamañom + 1);
			myAxis.getAxisPen().setVisible(false);
			myAxis.getGrid().setVisible(false);
			myAxis.setRelativePosition(100);
		}
		if (call == 2) {
			myAxis.setAutomatic(false);
			myAxis.setMaximum(tamañom + 500);
			if (tamañom > 300) {
				myAxis.setMinimum(tamañm - 300);
			} else {
				myAxis.setMinimum(tamañm);
			}
			myAxis.getLabels().setValueFormat("$");
			myAxis.getAxisPen().setVisible(false);
			myAxis.getGrid().setVisible(false);
			myAxis.setRelativePosition(100);
		}
	}

I've seen that you inserted a layout inside the class that I've posted, but I'm ussing it ass an object. I have a class A that calls this class, it's something like this:
code:

Code: Select all

RelativeLayout layout1 = (RelativeLayout)vista.findViewById(R.id.layout1);
RelativeLayout layout2 = (RelativeLayout)vista.findViewById(R.id.layout2);
private TChart gv_1 = null;
private TChart gv_2 = null;
gv_1 = new GraficaLineas(x1	, y1, getActivity(), mesg, 2).getGrafica();
gv_2 = new GraficaLineas(x2 , y2, getActivity(), mesg, 1).getGrafica();
layout1.removeAllViews();
layout2.removeAllViews();
layout1.addView(  gv_1);
layout2.addView( gv_2 );

This doesn't change the result for the particular charts I'm drawing, at least in respect to the issues reported here.

Find below the full code I'm using:
