custom tooltip

[Mulderone]

I'm using a line series graph with pointer.

How to create custom tooltip when i click on pointer ?

Thanks a lot for your answer.

[Mulderone]

I also want to custom the display of label to add an icon to represent a level for each y value

Hi Mulderone,

You should use a MarksTip tool as in the Tools -> Mark Tips examples at TeeChart.Features.jar demo.

Hope this helps!

i look at the code and test it but it's not precise when you touch the screen.

It's possible to add a listener on the SeriePoint or get the nearest SeriePointer for an X,Y coordinate ?

I understand that the android version share the same code as Java library but using mouse on PC is most precise, which is not the case on Android device.

I just want to touch a single point on the line series and draw a custom toast nearest the point.

Is it possible or not ?

Hi Mulderone,

Yes, you could use series' click event, its clicked method in chart mouse events or the NearestPoint tool.

[Mulderone]

Could you be more precise ?

the series accept only 2 listeners, i'm using the the serieMouseListener but i 'have a nullPointer exception when i touch the graph and i can't find the nearestPoint method

Could you help me ?

Code: Select all

final Series series = Series.createNewSeries(this.getChart(), Line.class,
					null);
			series.getXValues().setDateTime(true);
			/**
			 * Configuration graphique des points de la série
			 */
			final SeriesPointer seriesPointer = ((CustomPoint) series).getPointer();
			seriesPointer.setVisible(true);
			seriesPointer.setVertSize(6);
			seriesPointer.setHorizSize(6);
			seriesPointer.setColor(series.getColor());
			seriesPointer.getPen().setColor(Color.WHITE);
			seriesPointer.getPen().setVisible(true);
			seriesPointer.getPen().setWidth(3);
			seriesPointer.setStyle(PointerStyle.CIRCLE);
			/**
			 * Configuration graphique des tooltips de chaque point
			 */	
			final MarksTip marksTip = new MarksTip(
					this.getChart());
			series.addSeriesMouseListener(new SeriesMouseAdapter() {				
				public void seriesClicked(SeriesMouseEvent e) {	
					marksTip.setMouseDelay(0);
					marksTip.setSeries(series);

					Toast t;
					t = Toast.makeText(activity, marksTip.getSeries()
							.getValueMarkText(e.getValueIndex()),
							Toast.LENGTH_SHORT);
					t.show();
				};
			});

Hello Mulderone,

I'm not getting the error you are with that code but I see the MarksTip has an strange response. It has to be revised.
In the meanwhile, the following code seems to work better, could you please give it a try?

Code: Select all

	private static com.steema.teechart.tools.Annotation annot1;
	com.steema.teechart.styles.Line lineSeries;
	private void initializeChart() {
		tChart1.getAspect().setView3D(false);
		tChart1.getLegend().setVisible(false);
		
		lineSeries = new com.steema.teechart.styles.Line(tChart1.getChart());
		lineSeries.getPointer().setVisible(true);
		lineSeries.fillSampleValues(10);
		
		annot1 = new com.steema.teechart.tools.Annotation(tChart1.getChart());
		annot1.setActive(false);
		
		lineSeries.addSeriesMouseListener(new SeriesMouseListener() {
			
			@Override
			public void seriesExited(SeriesMouseEvent e) {}
			
			@Override
			public void seriesEntered(SeriesMouseEvent e) {}
			
			@Override
			public void seriesClicked(SeriesMouseEvent e) {				
				annot1.setActive(false);
				for (int valueIndex=0; valueIndex<lineSeries.getCount(); valueIndex++) {
					if (lineSeries.clickedPointer(lineSeries.calcXPos(valueIndex), lineSeries.calcYPos(valueIndex), e.getPoint().x, e.getPoint().y)) {	
						annot1.setText(String.valueOf(lineSeries.getYValues().getValue(valueIndex)));
						annot1.getShape().setCustomPosition(true);
						annot1.setLeft(e.getPoint().x);
						annot1.setTop(e.getPoint().y - 20);
						annot1.setActive(true);
					}	
				}
			}
		});

thanks for your help.

I've found a solution : a SerieMouseListener and i'm using a Toast object with a custom inner view.

I don't pop-up the toast near the point but the look&feel is ok
