evGraphClick parameters in Omnis Studio 8.1
Hi.
I’m using graph2 in Omnis Studio 8.1.7.
The graph I’m working on is of major type kG2xy and minor type kG2xyScatter.
I’m trying to use evGraphClick event to get the line number of the data element that received the graph click (I don’t care about the column, since it is a single set of data).
I enabled mouseevents in the graph component. But, using
On evGraphClick
Calculate locLine as pItem
I get locLine (pItem) always equal to 0.
Was it a glitch of graph2 components in Omnis Studio 8.1.7 or am I missing something?
Thank you!

Hi Massimo,
I tested this in the Graph2 sample library (available in the Studio Hub) and you can get the line number of the data element that received the graph click from the event parameter pSet.
There is no need to enable mouse events in the graph component for this to work.

Hi Götz.
Thank you. I guess it’s happening because my iGraphList is not well-formed. I’ll check more in detail.

Hi Götz. I got it.
My iGraphList is defined with columns X and Y that are Number, Floating dp. In this case, pSetname is NULL, it is returned only when X is Integer and is the value on the x-axis.
In case of multiple data, for example
Do iGraphList.$define(lName, X1, Y1, X2, Y2, X3, Y3)
only pSet is returned (in case all columns are Number, Floating dp) which is the $line of iGraphList. The parameter pItem is always equal to 1 and the others all NULL. So I don’t know how to identify the data series. i.e. did I click on (X1, Y1), (X2, Y2) or (X3, Y3)?
