Thanks, the solution worked.

David can you please let me know how to do this?

Yes its possible to customize legends. First you need to remove the existing legends from the chart using the following piece of code. //Remove all the legends from chart. for(int i=0;i<mycollection.getItemCount();i++){ chart.removeLegend(); } Now create LegendItemSource mysource= new MyLegendSource...

Thanks, But it did not work, The value returned by NumberAxis.getTickUnit().getSize() is always 1.0. Currently my Y Axis reads as 1575, 1600, 1625, 1650, ...... 2250,2275 and hence the step size here is 25. Is it possible to get this value. The Y axis will vary depending on the data. Please let me k...

I plot around 50+ [can go to 100] graphs and for each graph i have new XYSeries("Label") and each series i add to XYSeriesCollection(). I later use this collection to draw timeseries graph and when i add the data into the series i would have already sorted it. So will using the same logic new XYSeri...

David And Others please reply to this question.

Yes i did. My problem was that i want a specifc number of point[shape] and not a shape on each data point in data set. Adding XYShapeAnnotation will mark each data point in the dataset.
Hope i used was correct. It did work for me.

If you want a point [shape] on each point on the graph then use what you have done ,But if you want only one/two... points then try the following Here is what worked for me 1) Write a custom class class CircleDrawer implements Drawable { /** The outline paint. */ private Paint outlinePaint; /** The ...

To use JFreechart for web you will need to use only those graph types [with out controls that some graph types offer] that can be rendered as image.

JFreecHart ---> Image [Graph] ---> Use this as a image in your web app.
Hope this helps.

Go throug this link the same logic can be applied to get hyperlinks in graph when used with web applications.

This should give you a nice starting point.
Thanks

Thanks it was a nice pointer , Though i had to do a lot of google after the start you gave. Here is what worked for me 1) Write a custom class class CircleDrawer implements Drawable { /** The outline paint. */ private Paint outlinePaint; /** The outline stroke. */ private Stroke outlineStroke; /** T...

Since you are using jfreechart with Webapp then your graph would be dumped into one of your image tags say like this <img src="graph.jsp"/> Graph.jsp will dump the graph as PNG. Here is what you need to do Read this tut http://www.w3schools.com/tags/tag_map.asp 1) String toolTipFormat="{0}: {2}" + u...

Hi,
I have a time series graph , I want to highlight a particular point in the graph which will indicate the peak value in the graph , Is it possible to highlight a particular point say with green circle?
Please help.
Thanks
Deepak

Hi, I have a time series grpah where i display a label which indicates the peak value in the entire graph. Since my range is auto sometimes the label is partly visible. Is it possible to position the label? renderer.setItemLabelGenerator(new flagPeakToolTipGenerator()); renderer.setItemLabelsVisible...

I am newbie. I have a graph where the range is set to auto and the step size can vary depending on the data. For example if the Y Axis [Range Axis] is 50,100,150,200 ........ Here the step size is 50. I need to get this data. Is it possible. Please help. I searched the forum on how to get the step s...
