Ok... I do not get many comments on my posts (because they are short and boring) but am really looking for people to comment on this one because I am looking for feedback.
I have used CeWolf/JFreeChart for about two years now (off and on). If someone asked me to rank my knowledge of them (1 to 10) I would answer 5 - not an expert, not a novice. Recently, it has become common for my users to want time-based charts. It seems that JFreeChart does not provide much utility for building bar charts based on time series. Am I seeing this correctly? or am I failing to understand a fundamental concept of JFreeChart? (or... other?)
Any feedback?
I strongly encourage Java client/server/web technologies.
However, scripting languages continue to have a significant place in the market. Will Java be replaced? or will they live happily together?

Yes, JFreeChart supports this. One way to do it is to create a dataset using the TimeSeries and TimeSeriesCollection classes, then call the createXYBarChart() method in the ChartFactory class. See XYBarChartDemo1 in the JFreeChart demo collection for an example.
Um, I'm really embarrassed and will update my blog soon but did not realize the JFreeChart God would reply in person. ;-)
He is completely correct; In my haste, I came nowhere near asking what I truly wanted to know.
