I know how to group chart slices / bars below a certain threshold together

  • 0

I know how to group chart slices / bars below a certain threshold together into one bar. But if the data displayed in the chart contains lots of small slices, collecting slices below 5% or so results in a huge “other” slice / bar. On the other hand, if I collect only slices below a very small treshold, the chart could contain too much data to be readable.

So, I’d like to set a hard upper limit for the amount of slices, show up to n biggest slices and collect everything else into one “other” slice.

How can I do that with SSRS 2008?

Thanks,

Adrian

    I’m pretty sure this is possible to do in SSRS without rewriting your query. I think it will be easier to rewrite your query. However, given your parameters, I’ll carry on.

    I think this will take some serious experimentation on your part. Take a look at points #17 and #18 at http://www.ssw.com.au/ssw/standards/rules/rulesToBetterSQLReportingServices.aspx and see if it helps. They demonstrate a good way to set the scale of a chart based on the values in the row. It seems like you could combine this with a hard maximum using IIF(Max(MyColumn.Value) > @MyLimit, @MyLimit, Max(MyColumn.Value))

    This gets you half the equation, because now you know your limit. Now the trick is to stuff all values below a certain scale into the “Other” bucket. This can also probably be solved by some creative IIFing:
    Set the value for the label column = IIF(MyValueColumn.Value < @Threshold, "Other", MyLabelColumn.Value)

    Like I said, you’ll have to do some experimentation and it will likely be easier to rewrite your query, but if you’re stuck with SSRS only, at least you’ve got someplace to start looking.
