Hi all, An important update may be. Can some one tell me about creating image maps for bar graphs. Actually my problem is this : I write the entire chart as a png image to the outputstream. Now if my chart area is say 300 and 400 in height and width. And say i plot around 21 bar values on the graph,...

Are you sure about what you are saying ? Understanding HTML aint that difficult i guess ? Do you mean to say "There is no solution to this problem, for generating mouseover tooltips for bars with tooltip values = barvalues" in jfreecharts.

Thanks for the reply. Would be greatful if you could direct me to some examples of creating image maps. When my chart width is less and if the number of bars i show in the graph are more, then neither i get the values on the bars nor i get tooltips generated.

You need to enable xServer for java2d to be running. try the same piece of application on Tomcat. If u get DISPLAY 0.0 bla bla error then it must be something wrong with the java2d. Carefully read the FAQ's and in that there is one question which talks about when the same webapplication is shifted f...

you must be getting this error for all the classes (ex: categoryDataSet, pieDataSet etc) in the package. Use this. C:\Tomcat 4.1\webapps\faults\WEB-INF\classes javac -classpath "C:\Tomcat 4.1\webapps\faults\WEB-INF\lib\jcommon-0.9.6.jar;C:\Tomcat 4.1\webapps\faults\WEB-INF\lib\jfreechart-0.9.21.jar;...

We can expect in further versions of jfreecharts for chartRenderingInfo to be continued. Even if they decided to modify it still the functionality would be provided in else other way but there should not be a cut down in functionality just because of the upgrade in version. As long as we use the jar...

Its nicely explained in the FAQ's. It only requires u to enable the xServer for graphics java2d to be running. solutions for this problem are already provided.
