I'd like to create a dynamic chart layer based on values
passed by user (web-based).
For a similar thing, this boiled down to saving
the user-provided values in a CSV and setting up a JOIN
object to use them from getFeatureInfo template.
But for this new use case (charts) I can't wait till
getFeatureInfo for using the csv JOIN values. I have
to use them right in the layer classification. Ie:
LAYER
TYPE CHART
JOIN
FROM "iso2"
NAME "values"
TABLE "tmp/userprovided.csv"
TO "1"
CONNECTIONTYPE csv
TYPE ONE-TO-ONE
END
CLASS
STYLE
SIZE [values_2]
END
END
CLASS
STYLE
SIZE [values_3]
END
END
...
END
Is there any plan to make the above possible ?
Currently, with the above code, mapserver tries
to query "values_2" and "values_3" from the feature
provider of the layer (postgis).
