2014 curve expansion

[jack__]

Hello Otmar,

I installed 2014 SP1, unchecked the option you pointed out, and made sure I saved the .DDD file properly.  Now it just shows all my non-expanded curves (no wildcard selection) as black (the first color in the parameter list), and only shows a single black curve when I try to use wildcard selection.

Hello Jack,

That's odd, I tried this on all 3 PCs available to me for testing (I am at home this week on vacation, thus only 3 PCs) and it works on all of my machines.

Would you mind sending me the *.TDR REPORT layout file and the data file you are using to create the report? Feel free to sanitize the data as needed if any of that is confidential, I will need the structure of the file though. A TDMS file would probably be best. I would like to test this on my machines to see if there is some strange effect taking place.

I am leaving on a business trip on Sunday morning for a week, but I'll try my best to see if we can resolve this issue for you quickly.

Best regards,

Actually, I'm seeing the same problem as Jack if I am using X and Y channel pairs. The curve expansion only seems to work as desired with waveform channels.

Perhaps this is related, but it may be a separate issue. I have no DAC or Visual Panel on the left, even though I have 2014 SP1 installed. Is there a configuration setting somewhere to make those visible? I installed 2014 SP1 over top of the original 2014. Maybe I should have uninstalled the original first?

Ahh, yes I am using X and Y channel pairs and no waveforms.  It does work when I use waveforms like the ones in the example data set.  Good to know that I wasn't crazy and that I did follow the directions properly!

Is there any word on whether this is something that can or will be fixed to work properly with non-waveform channels?  Most of our data cannot be made into waveform channels due to varying sample rates within data files (not by choice, I assure you... it's a side effect of ASCII being used as the primary data logging format) and this would greatly simplify the report layout settings.

Jack,

I'm currently checking into this to see if there's a workaround, but it looks like you might need waveform channels to get the behavior you're looking for.

Hi Jack,

Here's the deal.  R&D considers the channel expansion feature to be explicitly for plotting a different color PER GROUP in the Data Portal.  DIAdem 2015 will plot all the "Data_*" channels it finds in the first group with one color (black, say), then it will plot all the "Data_*" channels it finds in the second group with another color (red, say).  This is true whether the curves are XY curves or waveform curves.  DIAdem 2015 32bit still has the (DIAdem 8.x) compatibility setting Otmar mentioned that will ignore channel grouping completely such that you can display waveform channels in the same group with different colors, but DIAdem 215 64bit (and future versions) has all the compatibility settings removed to make a fresh start for 64bit versions.

What you can do in any DIAdem version is put each XY pair in its own group in the Data Portal, then you can display them in different colors in all DIAdem versions using channel expansion.

Yep, that's about what I was thinking the solution was.  Yet another reason to try to get our data logging onto a sane path with one logging rate per file/group.

Thank you, all.
