Date series graph

Question

Here's another doozy:
I'm trying to create a bar graph that has dates along the x-axis and values up the y-axis. The dates will be approximately once a week over a year. According to the faq I should be able to do something like this:
http://www.oracle.com/technology/products/reports/htdocs/faq/graph_faq_with_style.html#q32
But how do I represent the data in the xml for the chart definition?
I've tried setting timeAxis attribute in LocalGridData but I always get an error.
If I have the dates as ColLabels then I just get the canonical date format shown and the bars are spread evenly, even though the sample in the faq shows that gaps should be taken care of.
It would also be nice to just show the months as labels.
The original chart was done in Excel.

Answer 1

After much hunting around, I found that the chart dtd technote is out of date and does not document as much as in the actual graph.dtd in the bipres.jar.
In there I found I needed a dateFormat attribute for the LocalGridData when timeAxis="true" and that I could specify timeAxisYearFormat="NONE" timeAxisMonthFormat="MONTH_LONG" in the Graph tag.
This will then work the way I want only if the dates are regular eg. same date in the month, but won't work if I have the same 2 days in the months.
I might try using every day of the year as columns and just have data for the days I'm interested in. Otherwise it looks like the graphing package can't handle my case according to https://metalink.oracle.com/metalink/plsql/f?p=130:15:1334228859318038841::::p15_database_id,p15_docid,p15_show_header,p15_show_help,p15_black_frame,p15_font:BUG,3002631,1,1,1,helvetica
Here is a chart def that works, but if I change the dates eg. add an entry for the 14th of every month, it won't work. The dates that I have are fairly irregular, on average once a week, but could be any day of the week.
