Multi series for a bar chart [message #144434]

I want to create a bar chart which can compare sales turnover between many
years.
I recover my data from a JDBC data source and i don't know the count of
years so the count of series. My Y-axe is the total sales turnover by
month and the X-axe represents the month. In this way i would like to
compare per month the evolution of the sales turnover.

How can i do that ?

In other way, i would like to use the mapping system with my X-serie
(month), because I have the number of the month and not the name. But the
mapping system is not available for chart series. I have replaced the
expresison of my data row["Month"] by a switch case for incating the name
of the month. But the X-Serie of a char need to be a number or a date, so
i can to that.

Can you help for this thing please ?

It seems I will need that kind of report myself.
Probably I will start on that even today.
So please keep me posted in case you will have some progress.
I have some ideas how to do that but I have to check it.

Inside initialize method of report do that:

var months = new Array(13);
months[1] = "Jan";

months[2] = "Feb";

months[3] = "Mar";

months[4] = "Apr";

months[5] = "May";

months[6] = "Jun";

months[7] = "Jul";

months[8] = "Aug";

months[9] = "Sep";

months[10] = "Oct";

months[11] = "Nov";

months[12] = "Dec";

reportContext.setPersistentGlobalVariable("months", months);

----------------------------------------------------------

After that click in layout mode on chart item and then switch to script tab.
There are plenty comment out chart script methods.

Uncomment function "beforeDrawAxisLabel" and put there code shown below.

function beforeDrawAxisLabel(axis, label, context) {

repCtx = context.getExternalContext();

objRef = repCtx.getObject();

months = objRef.getPersistentGlobalVariable("months");

label.getCaption().setValue(months[parseInt(label.getCaption ().getValue())]);

}

Thank you for your help, it's working as well. The script is not very
complicated, but i'm not used to use it yet.

For the multi series, i'm trying to make it working and if you succeed let
me a message please.

Ok, I got it.

I will explain how I did it for my query:
SELECT Year(Visits.Date) As YearNumber, Month(Visits.Date) As MonthNumber,
Count(*) as VisitCount
FROM canarsie.medbase.dbo.Visits Visits
WHERE
Visits.Date between @FromDate and @ToDate
Group By Year(Visits.Date), Month(Visits.Date)
Order By Year(Visits.Date), Month(Visits.Date)

step1:
Select subtype: Stackedbar

step 2:
Y series: row["VisitCount"]
X Series: row["MonthNumber"]
Optional Y Series Grouping: row["YearNumber"]

step 3:
Y Series Labels:
section Values: Value Data, Value Series Name

"Value Series Name" show year on the label.

If you have additional questions let me know.

Good luck,
Vladimir

Thank you Vladimir, it's working.

In fact, my error was that i used the grouping system directly in the
chart properties and my query contained no year and month expression and
no groups. I did everything by computed columns.

Now i have integrated all in my query and it's working.

Godd luck for your continuation
