DIAdem Idea Exchange

Post an idea

When dealing with large TTL data log files (approximately 25 Gb or more) in DIAdem using BUS CAN converter, users have reported encountering freezing issues during the conversion process.

Furthermore, if you check the Task Manager, it may show that DIAdem is not responding, which typically implies that the software has crashed. This lack of feedback makes it challenging to determine whether DIAdem is functioning correctly.

However, despite the apparent freeze, the conversion process eventually completes successfully after approximately 30 minutes.

To improve the user experience, it would be beneficial for DIAdem to provide clearer feedback during large file conversions, such as a progress indicator or status updates. This would help users understand that the software is indeed working and prevent unnecessary concern about crashes.

Thanks in advance!

I understand that DIAdem is not a console application, but a GUI-application. Therefore, a python command like

val = input("Enter value: ")

will not work because sys.StdIn and sys.StdOut are not available. However, this isn't well-documented and the error given isn't very helpful.

There are other more complicated outputs that I have seen in the console area of my regular Python IDE (I usually use PyCharm) that fail with very unrecognizable errors in DIAdem Python, usually a string of errors in many scripts that looks very intimidating!

It seems that DIAdem is just grabbing the simple "print" statements from Python scripts, and nothing else works. This would be ok if these errors could be bypassed somehow?

The VIEW "Layout Parameters" setting "Word wrap" value is not persistent and does not seem to be saved to the DIAdem desktop "Desktop.DDD" file. I think it should either be persistent or added to the saved parameters for the Desktop.DDD file. So if I change it, and close/reopen DIAdem, the setting is always changed back to deselected.

The workaround is adding "View.Settings.UseMultilineLegend = 1" to some startup script which is fine, but I'd prefer it to be persistent upon changing it.

I would like a feature where you can add extra paths in DIAdem's Python implementation for user-specific Python library directories.

In Visual Studio Code you can edit the settings.json to add paths to:

python.analysis.extraPaths (for importing)
python.autoComplete.extraPaths (for autocompletion)

So stuff imported from "C:\Repositories\Python\MyLibraryOther\__init__.py" is directly visible on import alongside stuff in SitePackages:

I've been able to add further locations to the active DIAdem Python Path via to use programmatically:

import site
site.addsitedir('C:/Repositories/Python/')

With that, I can "use" the script contents from both "Other" and "Site-Packages" items:

But currently I can only "see" items located within the Site-Packages folder:

Need a script command to disable the display of the local file system in the Navigator Browser window. This can be done through the user interface as shown in the attached image, but an equivalent script command is not published. Reasons:

1) Keep the user focused on using Navigator search within indexed search areas.

2) For custom applications powered by DIAdem

Many functions in DIAdem seem to be biased towards waveform channels, ignoring the classical ways of working with standalone numeric channels.

The ChnResampleFreqBased function returns waveforms when I think it should have the option to return standard numeric channels. My workaround is not to use it at all and to use the channel generation and linear mapping functions instead.

This obviates the need to reformat channels (wherein you also get a new X channel that you might not have wanted) and is less code. But why have to use two functions to get the same output that could have come from the one resampling function were it to have the option to provide numeric channels?

Regards.

Today I was trying to find the SCRIPT command for "Converting Numeric Channels into XY-Channels" and could not easily find it or record a script to find it. So two requests here: (1) when recording a script, output the script or have a message that says 'sorry!' and (2) update the help with the correct script functions, similar to the other channel conversion functions.

I tried to record a script, executing the ANALYSIS function "Channel Functions -> Channels <-> XY Channels", but nothing showed up in the recorded script.

Looking up the help reference for "Channels <-> XY-Channels" only shows how to display the dialog, Call SUDDlgShow("Main", ResourceDrv & "AnaChnToXYChn")

All of the other "channel conversion" help documents show how to do this in SCRIPT, for example, "Numeric Channels <-> Complex Channels" shows "

ChnConvertNumericToComplex", similar for the Numeric to Time, Waveform, etc. My proposal is below:

Script Call:

Call SUDDlgShow("Main", ResourceDrv & "AnaChnToXYChn")

Set Group = Data.Root.ChannelGroups(1)

Set XChannel = Group.Channels(1)

Set YChannel = Group.Channels(2)

Set YChannel.XRelation = XChannel

When I am loading multiple same-named channels into the Data Portal from a DataFinder Search Results list (after 'searching for channels'), if I load these channels into the data portal, by default they all load into the 'default' group, and because they have the same name, they are re-named inside the Data Portal with suffix numbers.

I think it would be better to create a new group in the Data Portal with the name of the group the channels belong to in their respective files, or at least provide this option.

When exporting plots of measurement analysis, unfortunately the reader can only see what was plotted and is not able to zoom / scroll through 2D plots or rotate 3D plots. Matlab .fig figures go into that direction but can only be used with Matlab.

I know there is a way to import 3D objects into a PDF, but I haven't used this so far. I've heard of the possibility to integrate Matlab plots into interactive PDFs - maybe s.th. like this can be made possible with DIAdem?

I think a document with interactively viewable plots would be a great advantage in discussing test results, and it would be a big advantage for NI DIAdem if the tool would be able to export plots / documents in such a way. Maybe PDF is an option - maybe there are other/better formats for this.

I have not found a straight forward way to label axes ticks with text instead of numbers, so I would suggest this as a feature in a new release. At the moment we are working with text fields which is a very cumbersome way and not very user-friendly when editing the report.

It would be very nice, if there would be a way to implement text labeling for x, y and z axis.

Example: I have a state channel that contains values between 2 and 8. This channel is an assignment channel, therefore I could create a corresponding text channel containing the status description for each value. This way, it would be possible to display a table but as the channel has 3600 values, this wouldn't be very readable and a 2D plot of the state events would be more helpful (e.g. state changing from off to passive etc.)

One could for example expand the axis scaling settings where a tick channel can already be assigned by a text + index or an assignment channel assignment.

Today I found a way of combining a bar plot and a line plot to achieve this goal, which still isn't a nice way:

- Bar plot: X channel is a numerical channel only containing NoValues [Nv,Nv,Nv,Nv,Nv,Nv,Nv,Nv] (we don't want to see bars), Y channel is a string channel which contains the Y-Axis labeling we want [ -,off,-,on,-,passive,-,idle] (we want our labels on Y-Index 2,4,6,8 - that's why the string channel has "empty values")

- Line plot: X channel is the time channel, Y channel is the state channel, containing values of the set (2,4,6,8)
