I am trying to create a custom SQL web-based report that graphs the number of UDT ports in use over time (I'm posting this in the NPM forum because this is a question about web reports)
SELECT month ,Sum(apc) MaxPortCount FROM (SELECT DATEADD(month, DATEDIFF(month, 0, DateTime), 0) AS Month ,upd.nodeid ,max(avgactiveportcount) mpc FROM [dbo].[udt_portusage_daily] UPD INNER JOIN nodes N ON N.nodeid = UPD.nodeid WHERE Datetime >= '2013-01-01' GROUP BY DATEADD(month, DATEDIFF(month, 0, DateTime), 0) ,upd.nodeid) X GROUP BY month ORDER BY month
I cannot get the report writer to display a graph of this data -- am i missing something?
it displays the information as a table, but I can't figure out why it will not draw a graph if the data.
