Hi all, I found out that: 1) if you actually replace \n (which is interpreted as two char by the default setter) by the one char '\n', you'll actually get a line break in the legend items and text block in general. e.g. I'm loading the text from an XML and it contains something like: Line & # 1 0 ; ...

Hi, whilst I've never used Jasper, what about using the methods described above for the creation of a high quality image and save it to a temporary directory/file and pass it's resulting path to the .jasper parser ? If the .jasper behaves like a jsp file, you could use also a static reference in the...

Hi,

I'm actually curious : "how" do you access the outlook (exchange server I suppose) data ? What library/API do you use?

I've heard about J-Integra... but is is neither free nor open source...

Thanks for the info

Thanks for the info (I was on holidays, just came back !) but I don't use JS, it'll be an all java application.

Best wishes for the new year to all that read this !

Thankyou for sharing your code :D it is approximately what I intended to do but I neither had the time nor the understanding of what the AxisState and Cursor were (which I still don't quite grasp....) to do it ! I haven't tried the code yet, but it seems to me that what you do is a bit of an overkil...

*BUMP ! Would anyone be so kind as to consider this message and actually say something about it ? I'm considering doing some changes in the sub-classes of Plot to incorporate a member that would store the axisSpace of the last drawned graph and adding a method to give access to this member variable....

Is it plausible to use the reserveSpace() of the ValueAxis class and the resulting AxisSpace to see if the point is in the Axis region ???

Would that be the way of going about it ?

Any suggestions ?

Whole chart clicking: identifying parts of chart

Hi I would like to build an application that will allow the user to build a chart in a WYSIWYG way. For what I intend to do, I would need to be able to identify what part of the graph the user clicked upon . i.e.: if he clicks on the chart on the range axis, he'll get an editor that will allow him/h...

Hi, I'm not quite sure where you stand at the moment and what you've actually already coded... My _chart object is actually an instance of JFreeChart class. You must get the BufferedImage from the _chart and not the contrary! Your line with BufferedImage gets the image buffer from the chart but does...

Is anyone thinking the same things as me about it or not? (about scaling problems, ...)

Hi all,

have I offended anyone in the development team or is there just too much work / holidays to have an answer to this post?

Could you just tell me if this information is being taken into account or if it is just discarded please?

Thank you

Hi, By "good resolution" you mean the resolution of the "file" the image is stored in? i.e.: the image file resolution? I'll re-post my actual working code on this topic in a while... I think you've missed a step that created a (very) big image (in memory) of the JFreeChart, and stores it in the fil...
