Hi David, thanks for the source code1 I was able to see it. There is an error (maybe typo) in DrawStringPanel.java (line 180). existing code (wrong)- TextUtilities.drawAlignedString(...) correct code- RefineryUtilities.drawAlignedString(...) I wasn't sure where to report this, so decided to mention ...

hi, I have purchased the documentation for JFreeChart. In that it mentions about this demo DrawStringDemo being part of the JCommon distribution. But I couldn't find the "demo" folder anywhere in the jcommon distribution? Can anyone please tell me where to find it? I really need desperately! thanks,...

Hi David, I'm plotting a scatter plot that has huge names for one axis (I'm using symbolic axes). As a result, the chart window decreases in size and looks compressed. Even if I try increasing the size of the panel and frame it does not help. any idea how I can make the chart window a normal size? I...

Hi David, Thanks for replying! I checked out those charts. It looks like the x-values are the actual data that needs to be plotted, and y-values are like 0,1,2,etc. based on the number of items (or symbols in my case) need to be plotted. Is that right? Also wanted to know that if my symbol names are...

Hi,
Is it possible to have a scatter plot with x-axis showing string labels and y-axis as numeric data? For eg;, if i want a scatter plot for the following data -

X,Y
----
A,1
A,2
B,4
B,3
B,5
C,6
C,9

I think the TableXYDataset does something like having the same x-values right?

thanks,
Juhi

Hi David, thanks for that advice. the flag for allowing duplicates if set to false will take care of the duplicate values in XY-plots right? I was also asking if there was some way by which I could have a graph showing a grid with different cells colored differently based on some parameters. If I ne...

Hi, Does anyone know how I can use the JFree classes to plot something like a Shmoo plot? Basically I need to have a graph that shows different cells in the grid colored and with some code (described in the legend). something like a broken bar chart - each cell of the bar has some value - like the w...

Hi, I checked the forum and did find a thread on thiss, but that was an old one. As I'm having this problem for the same reason - large amount of data having the same value to be shown - is there some solution to this apart from getting the JVM 5.0+? i don't or rather can't update the JVM at this po...

Hi David, I've seen that the charts can be saved as .png files and this happens really great with good precision. the developer's guide has a section that talks about saving images to pdf documents. Is it possible to save the image directly into another application such as MS Word, Power Point, Exce...

here is the fix, go line 117 in the HistogramDataset class and find for (int i = 0; i < bins.length; i++) { HistogramBin bin = new HistogramBin(tmp, tmp + binWidth); tmp = tmp + binWidth; bins = bin; } replace it by for (int i = 0; i < bins.length; i++) { HistogramBin bin = null; // make sure bins[...

Hi David, Thanks for that update! I had a question regarding duplicate values which I have not been able to understand. I'm using the XYSeries to create an XYPlot. by using the default constructor, it allows duplicate values. But in my plot I can see only 1 point corresponding to that (x,y) pair. Th...

Hi David, I've purchased the Developer Guide as it said that it would help in understanding how to create datasets. however, I haven't been able to find any section in it that really explains how to go about doing so. It just explains the classes and what they are used for. Is there some particular ...

Hi, I'm trying to draw a histogram from some tabular data that I have. I'm fairly new to using the JFreeChart library, so can someone please give me some pointers regarding how I can draw a histogram based on some data that I have? For example if my data is like this - 10, 12, 10, 12, 11, 13, 10, 11...

Hi, The existing ChartFrame class extends JFrame, so every new chart created opens as a separate frame. If I want all the charts to be contained whithin the same parentframe, then wouldn't the ChartFrame class extend JInternalFrame instead of JFrame? So, any ideas on how I could implement this? than...

Hi,

I had installed 0.9.18 earlier and started my project using that. where can i find a list of differences between 0.9.18 and 0.9.20 for JFreeChart? Also, for 0.9.18, it came with JCommon 0.9.3. Is this the same for 0.9.20? Clarifying this will really be appreciated.

thanks,
Juhi.
