Re: Borders of Category Markers

Upload an image of your chart to one of the free image hosters, then post a link to the image here.

Re: Adding JFreeChart to Itextpdf in Landscape

Ok, so start with some basic debugging.
What are the values for sizeX and sizeY?

Re: 1.5.0 Migration Issue

Thouhg this is now becoming more and more off-topic, I just wanted to provide an example for IMHO, a RectangleEdge class should be able to calculate an "aligned rectangle" from a Size2D object, an existing Rectangle2D instance, and an instance of each HorizontalAlignment and VerticalAlignment.

An itext forum is likely to be a better place to ask. if you post this question elsewhere, please mention the other post in this thread.

Re: JFreeChart Pan

I think that you may have accidentally mixed two different version. The classes PanHandler and AbstractMouseHandler are part of the FSE (future state edition) of JFreeChart, and they are missing in the most recent "regular" JFreeChart version (1.5.0). Instead of downloading patches and scripts from ...

Re: Sizing and Locating a JFreeChart with ItextPDF

As a first debugging step, you can check the value for "scale". If that happens to be 1.0, then the chart will cover the entire page. In that case, I could imagine that the definition of a new location is simply ignored.

Re: Sizing and Locating a JFreeChart with ItextPDF

Unfortunately no matter what I use for scale or Y location, the chart starts at (0,0) and covers the entire page. I can't reproduce that. I have changed my code from the other thread and converted the PDf Template to an image. Both setting the absolute position and scaling changed the layout of the...

Re: Issue with refresh of JFreechart

Do you call your method from an ActionListener? If yes, then your while loop is executing in the event dispatching thread, and the GUI will only be updated after the loop is completed. You need to run the code that is updating the dataset outside the event dispatching thread, and trigger an event wh...

Re: VectorRenderer - Add Color based upon Dataset

Hi Fred, Personally, I do not believe that a future JFreeChart versions will support your requirements. If you have some data in what form ever, it is your responsibility to make them available in a form that fulfills the constraints defined by the various dataset implementations of JFreeChart. You ...

Re: Adding JFreeChart to Itextpdf in Landscape

What kind of documentation do you need?
My code sample demonstrates you to create a PDF containing a JFreeChart as vector graphic.
Google should give you sources for both the API documentation and tutorials of itext.

Re: Adding JFreeChart to Itextpdf in Landscape

I have no idea what the singletons Chart and Image might be, but it seems that you create a bitmap from a JFreeChart and then integrate that bitmap into a PDF document. Is that a must-have? I am normally creating PDFs that contain the chart as vector graphic, that can be zoomed without loss of quali...

Re: 1.5.0 Migration Issue

What's the rationale for removal of marker support? Code simplification. Everything that can be done with markers can also be done with Annotations (see patch 316). Type safety with Markers is also somewhat ill defined. CategoryMarkers can be added to an XYPlot, and can be added as range marker to ...

Re: 1.5.0 Migration Issue

[*] stick with JFreeChart 1.0.x - I will make a new release on that branch with the latest bug fixes, but I won't be actively maintaining it going forward (someone else is more than welcome to do it); Does that mean than 1.0.20 is the last "official" version of JFreeChart 1.0.?
