I wrote a Dataset Add-In that goes out to an SQL database to grab data so that I can see the data trended in ProcessBook. The Add-In works great except I can't get the descriptions on the trend set correctly. The NamedValues passed into the GetColumnAttributes function only has Type, Zero, Span, Stepped, and UOM, but not Description. I tried adding a NamedValue (name=Description, value=some description) to the NamedValues, but it didn't help. I think it can be done, according to the IDataProvider3 GetColumnAttributes Method page in ~PIPC\HELP\en\pipbvb.chm.....
Does anyone know how to set the Description for a new dataset?
The Add-In implements PBObjLib.IDataProvider3, and is written in VB.Net 2008. I have ProcessBook 3.2.0.0; PI-SDK 1.3.6.364.
Thanks in advance!
<- The descriptions on the bottom are all blank
How long are you description? I ran into a similar problem and it was the length; only a certain percentage of the graph area is allowed for descriptions. If the description is too long it is simply not shown. It is scheduled to be fixed in v3.3; the techsupport site has more info.
