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. 

I've noticed that the easiest way to relate a channel calculation back to the original channel is to append to the channel name:

iH_EngSpeed_rpm

iH_EngSpeed_rpm_RegX

iH_EngSpeed_rpm_RegY

iH_EngSpeed_rpm_1

iH_EngSpeed_rpm_2

iH_EngSpeed_rpm_Filtered

Filtering for *engspeed, or *engspeed_rpm will return all of the above channels, but in my experience I rarely want to see all the additional channels...With enough channels, it can effectively obscure the channel you're looking for!

The simplest way I can think of to obscure these with the current functionality would be to have a stop character ("\"?) to prevent the filter from grabbing anything beyond that point:

*EngSpeed_rpm\ would return anything ending in *EngSpeed_rpm

Another way would be to get rid of the assumed * at the end of the filter, forcing people to put one on themselves when necessary (but that would be changing the current functionality and would likely confuse users at first):

*Engspeed_rpm would return anything ending in *EngSpeed_rpm

*EngSpeed_rpm* would return everything with EngSpeed_rpm inside it

This would also be nice for looking for channels that end in something, like anything ending in *nm\ rather than anything with nm in the name...

Simplify how to create a DataPlugin. I should be able to define a binary layout like a telemetry stream and directly assign channels.

For example, A new GUI would be created. I define the telemetry stream which has three floating point numbers then an integer, repeat. Assign channel names Volts, Amps, Power Out, and Setting. Perhaps set the built-in properties. Press a button the plug in is automatically created.

I would like this for custom pinning functions specific to our needs (like pin all channels of same name) and for the calculation manager (if a calculation's equation is defined as a channel property, re-calculate it or bring up the calculation manager, etc.)

Title says it all.  I don't like waiting while files load.  Can this process be threaded?

Hello.

The data reduction on loading could be extended to facilitate partial loading of large data sets:

Currently, it shows 'intervall width' or 'interval number' and 'reduction method (1st value, avg. min, max)'.

I'd love to have an option to define start value and data count, too. Similar to the FFT-timing dialog, where 'start/number/width' can be defined. Today, I always load the full data set, display in view, mark the relevant area and crop via 'mark data' and delete. Works ok, but when I know that I will need maybe the first 5 secs of a 10 minue measurement for one evaluation, it could be done easier, if I only load what I need.

Thank you.
