I save them temporarily in the HTTPServlet request object and then I retreive them later via the <jsp:useBean> in my JSP. The problem is that each jsp:useBean has an instance of a chart type stored in it (i.e., PIE, BAR). So, based on this, I am not sure how to store multiple instances of the same c...

It is possible for me to have several data sets for one particular chart type (i.e., PIE, LINE) that I need to display on a single web page. Is this poss...

I have spent weeks doing some extensive testing and I have found that Collections can not be read through the cewolf:param tag. I populated some dummy data in my producer bean to do the testing. When I put the ...

For a given chartName, I want to provide a single TimeSeriesCollection that takes in all of my series labels and all of the data points for those series labels. I do want a label produced for each datapoint. So, I may perform a query in the DB and my result set may have a chartname and 8 series labe...

In the TimeSeries constructor I am already reading in a "chart name" for that particular graph. I am retrieving my data set points (Date,Integer) out of the DB. For each data set point I have a series label name that should be displayed on the graph. For example, my query to the DB, will produce the...

But, I also have a list of labels (Strings) that I need to read in which will be the names of the different lines that are produced (based on...
