Once I needed a way to fetch more detailed data from a remote resource when the chart is zoomed. For this I derived from XYPlot and implemented the data request in the zoom*Axes methods. The annotations have funtions to set x and y positions. Maybe you can meet your requirement this way, too.

ok... thx for the info

Hello All,

is there a way to specify a dataset for a xytextannotation for use with multiple axes?

Hello All,

for on screen display I use a table which shows the values for datasets at the mouse cursor position. Showing the legend in parallel to this table is not needed. For printing it would be great to have the legend. Is there a way to only show the legend on print outputs?

hi craig,

hm strange... could u please post code of your chart so that i can check where the error is? i would not handle this issue in the axis code because the area selected for zooming is determined earlier.

hello dabid,

afaik selecting points is not implemented in jfreechart but if u are interested in doing so, have a look at how the crosshairs can lock on data. this might be a good starting point to understand how things work inside jfreechart.

hello david,

i just fixed/added some german translation stuff and uploaded it to the sourceforge patch area.

just rotfl... this is not a general purpose 'solve my problem' forum... as this has nothing to do with the core of jfreechart, don't expect anyone to reply in a different way as i did...

hello craig, i had the same problem with a line chart. as zooming seems to be implemented the same way for all charts u can do the same changes as i did. if u do, please give feedback if it works. any feedback by david is very appreciated as well, of course. :wink: u can fix it in org/jfree/chart/Ch...

there are a few samples included. look in this directory:
jfreechart-1.0.0-rc1\source\org\jfree\chart\demo

but i recommend buying the developers guide. look here:

hello david, this is a first but wokring try. please have a look at it and tell me if it's the right way to go. diff -ruN -X jfreechart.exclude jfreechart-1.0.0-rc1-orig\source/org/jfree/chart/plot/CrosshairState.java jfreechart-1.0.0-rc1\source/org/jfree/chart/plot/CrosshairState.java --- jfreechar...

This is not a problem of jfreechart. Try to get a good book to find out more about java. In this case you forgot to tell the java compiler where to find the jfreechart library. The easiest way is to copy jfreechart-1.0.0-rc1.jar into the same directory as your First.java file and compile it like thi...

Hello David, first of all, thank you for your fast answer. It's great to hear that you will continue working on this project. I like jfreechart very much and I am willing to help in some parts. The problem is that if you don't find any core developer to discuss strategies etc. it's always difficult....
