Thanks Dave-

I was afraid you'd say that :)

I will have to try and make it settable- once it's updated with the size, I would think I can notify it to auto update/draw again.

I'm wondering and I've searched, but I haven't found- is there any observer / observable code here to be used?

XYDotRenderer with Dynamic DotWidth DotHeight ?

Hello- I have a large dataset (5x 30k points) that is viewed in several different JPanels. All of the panels (save one) are linked now on zoom as to go to the proper locations. I now need, however, to make the individual points 'larger' as a 1x1 pixel, while looking great for this large dataset on t...

I haven't been able to get my 3x JPanels to work with JFreechart. I need one 'overview' graph on the left and three 'data' graphs on the right. I originally designed the form with JPanels for containers, but that doesn't work... Good luck- if you find a solution let me know. It was necessary to add...

If all the plots share the same domain axis and range axis, they will zoom in unison. Try somthing like this NumberAxis l_domain = new NumberAxis("domain"); NumberAxis l_range = new NumberAxis("range"); XYPlot l_plot1 = new XYPlot(l_dataset1, l_domain, l_range, l_renderer1); XYPlot l_plot2 = new XY...

This is intentional. The domain (X) axis is shared by both subplots, so a zoom on one subplot will alter the domain values displayed on the other. But the range (Y) axes on the two subplots are independent, so a zoom on one subplot won't affect the range axis on the other subplot. Thanks Dave- I co...

BUG: CombinedDomainXYPlotDemo un-zoom mis-sets domain axis

Would someone confirm this is a problem and just not me? To reproduce: Start the 1.0.4 Demo code. Choose 'Combined Axis Charts' Choose 'CombinedXYPlotDemo4' (valid with nearly every other combined chart) In the top chart panel, zoom in on a region (I picked 3x line intersecting). In the bottom panel...

Re: Zoom across multiple charts

I have read on some older posts (2002) that zooming across multiple charts has some issues. Is this still the case? I have 2 or more time plots that when zooming on one I would like to apply the same zoom to the other plots (zoom to the same time region). Any examples I could read thru for how to d...

Correct way for displaying 10 different 'types' of data

I'm hoping to get some feedback on a method of displaying 10 different types of data from a series. I have sequential time data- each point could have up to 17 different things 'wrong' with it. Each one of these problems should receive a different colour- and I do this by setting up a series of vect...

1.0.0.pre2 breaks ItemLabels for XYRenderer (labelGenerator)

Hello- While I've not been able to solve my visible ticks and visible data values problem, I just gave 1.0.0pre2 a run with the graphs I had gotten working (values only). What has happened is the label generator code is not working anymore. For example: public JFreeChart createLogBigYbyPatch_jFree()...

XYItemRenderer+XYLineAndShapeRenderer: Can I get labels too?

Hello- I'm trying to produce a graph that has text labels (values) next to the points as well as the shapes displayed. The old code I had written used XYLineAndShapeRenderer , but that never supported StandardXYLabelGenerator . The new code uses XYItemRenderer , but that doesn't support setSeriesLin...

Tooltips stop working after call to XYLineAndShapeRenderer

Hello- I've added 3 lines of code to display the data points on the line. When I call plot.setRenderer(renderer); the tooltips no longer function. Commenting out that line (obviously) allows the tooltips to appear again. Suggestions ? /* * tstJFreeChartLuminance.java * * Created on November 10, 2004...
