New channel type "calculation channel" in Data Portal

Status: New
by Member JuliaDawkins on ‎06-08-2011 09:54 PM

Rather than a channel that has a "fixed" value (numeric or string), this new "calculation channel" type would be a function of other channels.  Currently, if Channel3 = Channel1 + Channel2, and then I change the values for either Channel1 or Channel2, I have to re-execute the calculation

 

ChnCalculate("Ch(""Channel3"") = Ch(""Channel1"") + Ch(""Channel2"")")

 

Now, if there was a "calculation channel" where I could define Channel 3 as "Channel1 + Channel2", I wouldn't need to perform this re-execution! 

 

Another way to explain is to have a channel that works like Excel calculation cells.  The cell calculation stays the same, and when the input cells change, the result cell is automatically updated. 

 

I'm not sure if I explained this well, please ask for clarification if necessary.

Hi Julia,

 

I've wanted this exact functionality for a long time.  Thanks for bolstering my case with R&D.

This is a must.  Since most of your users are probably coming from an Excel background, they expect this capability to be there.  When I started using DIAdem, I was pretty surprised that all calculations didn't work this way.  I feel that without this feature, I have to fall back on scripting a lot more.
