Ok I find a way : Point p = getMousePosition(); XYItemEntity entity = null; entity = (XYItemEntity) chartPanel.getEntityForPoint(p.x,p.y); System.out.println("p :" + p); System.out.println("x :" + chartPanel.getChart().getXYPlot().getDataset(entity.getSeriesIndex()).getXValue(entity.getSeriesIndex()...

I have a little problem ...

I have a point in screen coordinates
There is a way to know if this point is in a dataset chart ?

We use this code public class DefaultChartPanel extends ChartPanel implements MouseWheelListener .... public void mouseWheelMoved(MouseWheelEvent e) { if (e.getScrollType() != MouseWheelEvent.WHEEL_UNIT_SCROLL) return; if (e.getWheelRotation()< 0) increaseZoom(getFocusedChart(), true); else decrease...

For the legend I try to use the BlockContainer this is the code : LabelBlock labelblock = new LabelBlock("LEGEND", chartfont); labelblock.setPadding(5D, 5D, 5D, 5D); BlockContainer blockcontainer = new BlockContainer(); blockcontainer.add(labelblock, RectangleEdge.TOP); BlockContainer blockcontainer...

Can someone help me on this topic?

Hi all,

We have two questions..

1. Can I add more legend in a XYLineChart ?

2. There are a way to add title in a Legend ?

Something like :


many thanks
Luca

It's Ok, many thanks!

2. Just use the defaults, i.e. let the axis decide which tick spacing is the best? :?: The uers can change the tick step in our application, but we need a way to reset the user setting and restore the defaults setting. How can we restore automatically tick spacing ? Is not possible put some marker ...

Hi, WE have a problem with the tick units.... :-( This is the code: double step = 10.5; // double representing the step int tick = 5; // int representing the tick units String fmt = "0.00E0" //string representing the format if (fmt == null){ format = NumberFormat.getInstance(); }else{ format = new D...

I used it in a wrong place...

Now all it'ok

thanks

I have the same problem : XYLineAndShapeRenderer renderer = (XYLineAndShapeRenderer) chart.getRenderer(); // Set the shape renderer.setSeriesShape(1, symbolRFProp.getSymbolShape()); // Set the color for this series renderer.setSeriesFillPaint(1, symbolRFProp.getFillColor()); // Set the color for sha...

I find a way without change source code: // c is the ChartPanel if (legend == null) legend = c.getChart().getLegend(); boolean showLegend = ((BooleanProperty)showLegendProp).getValue(); if (showLegend) { // Show the legend in the chart and update the properties legend.setItemFont(getFontValueOf(getL...

Good morning, We are using a JFreeChart for our applications. We need to show or hide the chart legend, example : boolean showLegend = (BooleanProperty)showLegendProp).getValue(); if (showLegend) { // Show the legend in the chart }else { // Hide the legend in the chart }
