Change of cursor on data

Hi,

Is there any option in jfreechart to change my cursor when on data ..

for example the mouse pointer is an arrow and it should change to hand when on data .

Thanks and regards
raghavan

Hi,
Do you mean that you want the data to represent as a link. Then JFreeChart has a capability to represent a data as a link in which case the cursor would be a hand, and you can place no destination for the link, so that no action is performed when u try to click...

Laks.

Yeah something just similar to that.

If the present cursor on the entire chart is pointer and when You move your cursor on the plotted data can we change that cursor to hand ..

Thanks and regards

Hi,
I saw this forum, I thought that it might help you...
http://www.jfree.org/phpBB2/viewtopic.php?t=21649

Also look at the example below...

// Create tooltip and URL generators
SimpleDateFormat sdf = new SimpleDateFormat("dd-MMM-yyyy", Locale.UK);
StandardXYToolTipGenerator ttg = new StandardXYToolTipGenerator(
StandardXYToolTipGenerator.DEFAULT_TOOL_TIP_FORMAT,
sdf, NumberFormat.getInstance());
TimeSeriesURLGenerator urlg = new TimeSeriesURLGenerator(
sdf, "bar_chart.jsp", "series", "hitDate");

// Create the X-Axis
DateAxis xAxis = new DateAxis(null);
xAxis.setLowerMargin(0.0);
xAxis.setUpperMargin(0.0);

// Create the X-Axis
NumberAxis yAxis = new NumberAxis(null);
yAxis.setAutoRangeIncludesZero(true);

// Create the renderer
StackedXYAreaRenderer renderer =
new StackedXYAreaRenderer(XYAreaRenderer.AREA_AND_SHAPES, ttg, urlg);
renderer.setSeriesPaint(0, new Color(255, 255, 180));
renderer.setSeriesPaint(1, new Color(206, 230, 255));
renderer.setSeriesPaint(2, new Color(255, 230, 230));
renderer.setSeriesPaint(3, new Color(206, 255, 206));
renderer.setShapePaint(Color.gray);
renderer.setShapeStroke(new BasicStroke(0.5f));
renderer.setShape(new Ellipse2D.Double(-3, -3, 6, 6));
renderer.setOutline(true);

// Create the plot
XYPlot plot = new XYPlot(dataset, xAxis, yAxis, renderer);

There is a feature call TimeSeriesURLGenerator and there might be other similar URLGenerators like this, see it in the API of jfreechart and you can provide no destination to the link (or you can give a destination if you want to direct a user to different page on clicking), in which case you will get a mouse cursor instead of the pointer when u move your mouse to the data...

Hope this helps you...

Thanks a lot lukkumar ...

The link u have given is what I am looking for .. thanks a lot .

The example you have given only changes the tooltip text not the cursor type ..
