CombinedChart: Bug with HorizontalDataAxis - Help Please!!!!

[Hari]

Hi,

I'm really impressed with the CombinedPlots but I got stuck with the combined chart having different Date Ranges.

For example, I have a TimeSeriesDataset ranging from, say, 1st Jan 2002 to 15th Jan 2002 and an another TimeSeriesDataset ranging from 1st Feb 2002 to 10th Feb 2002. I expect the proper output, one plot showing graph on left side and another on rightside of the combinedchart. However, I'm getting only one plot output for the entire width and the other is completely missing.


Here is the sample code, I used for testing. Please give me solutions to solve this problem. Thanks in advance.

Hi Hari,

Your post is the model on which all requests for help should be based...a short self contained demo program that illustrates the problem exactly! I'm only sorry that I haven't managed to work out what is going wrong yet...the code for combination charts was written by another developer so I'm not so familiar with it. But I will keep trying (and I'm going to e-mail Bill Kelemen to see if he has time to look at it also).

Regards,

Dave Gilbert

Hi David,

I too went through the source and could not find the origin. I personally sent an e-mail to *Bill Kelemen* regarding this problem. Let's wait for his reply.

Regards,

Hari.

[David Gilbert]

Just an update on this one. Bill Kelemen has found and fixed the problem. The next version of JFreeChart (0.7.4) will incorporate the fix. Thanks to Bill and Hari for the time they've put into resolving this.

Regards,

Dave Gilbert.
