3. Overlay for SWT Chart Composite    jfree.org

First, Jfreechart is an excellent product, thanks to all who have contributed to its development. My question is, does anyone know if the Overlay feature has been implemented for version 1.14, and if not is there any work being done for this for future releases?

5. Home for SWT JFreeChart?    jfree.org

Thanks for that, "silent". At first your recommendation didn't seem an option - since the target application is an open-source app for which no licensing costs are required. On reflection though, the "unlimited distribution" cost is less than I'd expect SWT-JFreeChart to cost, and it may be an option. I'll save RChart as a "fallback" option. Cheers, Ian.

6. Licensing question and SWT    jfree.org

I would like to make use of JFreeChart from within an Eclipse Rich Client Platform (RCP) application I am developing. 3 questions: (1) Am I ok to repackage JFreeChart as an Eclipse plugin (or indeed have you already done this)? (2) If I am do you have any preferences for a plugin name. The Eclipse conventions would suggest org.jfree.chart but I ...

8. JFreeChart port to SWT    jfree.org

Hi JfreeChart users, I've just completed a good step toward porting JFreeChart to the Standard Widget Toolkit. Following my last week stuggle to run my program on a free stack, I figured out the best way would be to have jfreechart running natively on top of SWT. I finally decided to give it a shot and I just came through after ...

I'm trying to open a new window with a JFreeChart plot, from a swt rcp application, but when I just instantiate an object, it says: "An error has occured. See error log for more details."

21. Change default zoom behaviour in SWT    jfree.org

Hi, Is there a recommended way to change how ChartComposite handles zooming? At the moment, it handles rectangles drawn left-to-right (zooms) differently from rectangles drawn right-to-left (restores auto bounds). Is it possible to have both of these delegate down to the plot so that it can decide how to handle both circumstances? -Dan

23. XYImageAnnotation with SWT    jfree.org

Hello, I wanted to use an XYImageAnnotation in a Chart. I'm using JFreeChart with SWT, so ChartComposite is my Container, where I put the Chart. The problem was, that XYImageAnnotations didn't apear in the chart, while other Annotations like TextAnnotations appeared. So after a few hours of debugging I found out, that using SWT, the object g2 in XYImageAnnotation.draw(Graphics2D g2, XYPlot ...

25. ****News on JFreeChart in Swt!!!****    jfree.org

Hi Kenzo, It's not decided yet but I think the experimental SWT branch will be in the moved in the main tree in jfreechart 1.2.0. Regarding your second question, it's not very clear to me what you're asking. The experimental code already do that (you do not need the method SWT_AWT.new_Frame). It's quite stable now, but there are a few things ...

26. SWT support    jfree.org

I'm just starting out with JFreeChart and I'm trying to build the swt ver. but I'm get compilation errors.

Also I just found a jfreechart-1.0.9-swt.jar in the lib dir, what ver and os ver of swt ...

27. SWT and zooming functions    jfree.org

I tried again, and I got new elements, especially with this example : gashalot.com/software/JFreeChartSWTDemo.java In an isolated app, I can use zooming function using ChartComposite instead of ChartPanel, only if I'm using this kind of code after displaying the chart : // standard SWT dispose loop while (!parent.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } but it's not satisfying at all, because in ...

28. SWT fails to refresh after I add data to chart    jfree.org

The way that I create the chart is that I first create the dataset TimeSeriesCollection dataset = new TimeSeriesCollection(); dataset.addSeries(series); And then I create the chart ChartFactory.createTimeSeriesChart(....)

30. SWT chart grid looks blurry (Antialiasing)    jfree.org

Hi there, it seems like the antialiasing feature affects the appearance of a SWT chart grid so the lines are a bit blurry, which is not the case when using an ApplicationFrame. Is there any possibility to use antialiasing only for the data line itself (in the case of a line chart)? Regards, Sebastian

33. JFreeChart & SWT - How to redraw?    jfree.org

Hi everyone, I've been working on a project with SWT and JFreeChart. In the program there is a SWT Listbox, when the user click on an item of the listbox, correspondant data is pulled and displayed with org.jfree.experimental.ChartComposite. The problem I've occurred to is how to update the ChartComposite properly. It seems neither redraw() or update() would do the job. Though ...

34. changing charts displayed with SWT    jfree.org

38. Gradient IntervalMarker in SWT?    jfree.org

I tried to do an interval marker with a gradient paint, and I only get one color, not the gradient. I'm using SWT. I tried the DifferenceChartDemo2 in an SWT ChartComposite, and I got the same (non-working behavior). I just get red for the marker. Is this an known SWT issue? Is there a workaround?

41. How to use JFreeChart with SWT (includes sample code)    jfree.org

I have seen a number of posts asking how to use JFreeChart within SWT applications. Most solutions appear to rely on converting AWT Image's into SWT Image's. That process works fine, but seems overly tiedious. Newer SWT implementations are beginning to provide very rough wrappers around a java.awt.Panel that allow older AWT/Swing components to be reused inside of SWT applications. Currently ...
