Diadem should use the tdms-format as default for saving

Changing the order of opened scripts (tabs) manually would be awesome feature. Now its a bit frustrating when u got scripts in different folders and you would like to change the order when you work on more than one script.

I love the new buttons on the data portal in DIAdem 2017 (delete, save, save as) but I'd like an "open" button too!

In some cases, the visual interface becomes very confusing and mixed up. Is it possible to develop a function to form layers like in the dialog editor? 

It would simplify the work in complex dac plans very much.

storethere.jpgMany DIAdem ANALYSIS functions offer storing the result in the original channel. And if this is not chosen, result goes into 'default group'.

My suggestion is to add another checkbox to chose storing in the group of origin.

Then, if I do an analysis over 25 groups (a typical number in R&R studies) each group will contain the calculation results of their own source data.

OK, I can call set default group. But still, I'd like to be able to use that feature :-)

Hey All,

 

I've been working with a lot of SUDs lately and I've thought of a few things that could help make their editing process easier. First off, it would be nice to be able to view the SUD script and the display at the same time. I think a split screen view of the display and the script would help streamline SUD creation. It's a bit cumbersome to have to switch back and forth between the two.

The other idea is to make layer  editing easier. Having faster way to switch which layer you are editing and a checkbox to select which one is the true default are a few ideas. I've run into a couple of occasions where I am editing one layer that is dependent on the first and have to switch back to the primary layer to test the SUD before switching again to continue editing. Additionaly, it would be  easier to edit layers if we could more quickly switch layers, through use of something like the tab system used to switch which sheet you are looking at in the report. 

 

Let me know what you think,

Make an option to have REPORT auto-scaling work like VIEW:

VIEW updates the Y-Axis range to be appropriate for the presently visible data when Y-Axis auto-scaling is on and a manual X-Axis range is selected.

REPORT presently maintains the Y-Axis scale of the entire Y-Axis channel's range regardless of X-Axis range selection.

 

DIAdem Axis Scaling Behavior.jpg

 

The current behavior requires the user to manually scale both the X and Y axis, when manually selecting an X-Axis range on a highly variable data set.  In my case, I'm setting the X-Axis range in a script (last 30 days), but will now also have to determine and set a manual Y-Axis range for the 30 day window of X-Axis values.

 

I put "Optional" in the description because sometimes the current behavior is desired (if the user wishes to maintain a consistent Y-Axis at all times).

Hey everyone,

There should be an integrated feature in DIAdem to create Boxplots. You can already find the min Q1 median Q3 and max in the analysis portion. I have not been able to find a good way to make a boxplot in DIAdem, and it's a very clunky process in excell. I've had to use DIAdem to process data then export the interested channels to excel to make acutal boxplots, which still requires a lot of manipulation.

To do this in excel you create a modified boxplot based on the difference in the five number summary. These numbers are put into a stacked boxplot, then the settings are played with to give the finalized look of a box plot.

The Differences plotted as a stacked bar plot looks like the following with borders on and the bottom and top sections made invisible with error bars to mark the min and max values

There should be a way to do a similar process, or even an automatic box plot creator in DIAdem.

 

Let me know what you think,

I have a project where we have a fixed TDMS "schema" (layout and properties) which are used by a data server to import the files.

I have found that opening and saving the files in DIAdem causes any spaces to be replaced with underscores. From the perspective of my data server the file is now corrupt.

 

I would like DIAdem to support these spaces as they are clearly supported by the TDMS specification.

Hi all,

sometimes it can be an advantage for data manipulation to have the possibility to access to an index channel (a channel just containing the values from 1 to n) generated out of channel with length n.

Such a channel would be helpful when using event search function which have to be performed on a certain number of values o in a certain block of data in a channel.

This function could be integrated in the current function "Generate Numeric Channel".

Best regards

 

 

 

Hi,

 

At present there are a number of ways to apply Y-Axes to a collection of curves on a 2D Curve chart, as shown:

 

View_Image_Example_1.png 

But my colleagues and I think it would be useful if there could be a button that generated an axis per unit type (e.g. Volts, Amps, DegC). That way like curves can be compared on the same axis without the distortion of larger number curves skewing the perspective of the axis.  

Dears,

I want to propose a check button in settings which would say something like "Automatic CodeCompletion". If you check that, you will see the hint from CodeCompletion anytime you write code not only when you write and hit ctrl + spacebar.

 

 

DIAdem has a data reduction option which can used in DIAdem Navigator to reduce the data beeing loaded but if it is up to do it after teh loading one needs to write a script or formula to do it.

I think it would be a great interest to have such a simple functionality  in DIAdem Analysis too that cna be applied to the internal data (i.e. results of calculations).

 

 

 

First of all, I really like the new ParallelProcessing feature which allows great time savings. The thing that sometimes makes it a bit cumbersome is that when you want to use it, you always have to define at least two additional script files, the worker script and the callback script. This is especially annoying as the SCRIPT-view is not particularly user-friendly when you work on different scripts at the same time.

An example is an evaluation script where you want to filter a series of rather long channels. There is potential for huge time saving doing it in parallel. Today, you would have to create a separate worker script around the ChnFiltCalc-function and a separate callback script to pass the filtered channel back into the main data portal. If you now have several of those smaller operations distributetd over your main evaluation script, you will end up with a large number of scripts unless you come up with a smart way to pack everything into just a pair of those.

What I propose is a sub-environment for worker and callback (like function or sub), so that you can pass subtasks to the workers from within the main script, e.g. without the need to create additional VBS-files. 

Referring to the example above where oMyEvalChn is one of the signals that I want to filter, it could maybe look like this:

Worker MyWorkerScript1(oChn)
  Call ChnFiltCalc(...oChn...)
  Callback = ChnToArray("/Filtered")
End Worker

Call oMyWorker.Run(MyWorkerScript1, oMyEvalChn)

Some operations in DIAdem can take a long time to complete (case in point - while writing this I am waiting for it to draw a 29 million point waveform on a graph!). Any operation which could take more than a few seconds should have a 'cancel operation' button to abort the current operation.

 

What I'm thinking is that after 2 seconds of waiting, a 'stop' or 'abort' button should appear in the bottom-right status bar where the progress bar appears for certain operations.

 

At the moment, the only way I can find to end the operation is to terminate the process in Task Manager.

 

 

For non-waveform channels that have a certain channel property populated that specifies another valid channel to use for the X-axis, it would be great if users could simply drag and drop channels into a VIEW 2D Axis System WITHOUT having to also select the x-axis channel.

 

(Over) Simplified logic:

When dragging a channel from the Data Portal to a 2D Axis System:

 

IF 'Waveform' channel property == No AND IF 'Xaxis' channel property specifies another valid channel,

THEN use this other valid channel for the X-Axis of the channel being dragged.

 

Example 1:

Let's say we have an internal combustion engine for which we are recording several channels at a rate of one sample per engine cycle. As the engine speed goes up or down, there is less or more time between each sample. This means we can NOT use a waveform channel. We must have an associated time channel for these several recorded channels. In this time channel, we will record a timestamp value when each engine cycle occurs.

 

Example of 'Xaxis' channel property value:

"Time Channels\Time Stamp Engine Cycles"

 

Example 2:

Let's say we are recording channels at a known rate, such as 100 Hz. A waveform would normally work for this. However, in this example, there will be gaps of no data in these data channels. These gaps may be relatively long in duration and we therefore do NOT want to record NO VALUE during this time, which would bloat our data files. We also do NOT want to put this data in separate data file nor in separate groups. This situation happens in MANY scenarios for us. For this, we must have an associated time channel for each of the data rates, such as "Time Stamp 1 Hz", "Time Stamp 10 Hz", "Time Stamp 50 Hz", and "Time Stamp 1000 Hz".

 

For both of these examples, plotting such non-waveform channels in a 2D Axis System could take less work on the end users' part, if we could add a little smarts to this drag-n-drop plotting operation. Implementing something like this will make creation of plots with meaningful x-axis values for non-waveform channels as easy as plot creation for waveform channels.

I am sure that this is far from a 'new idea'.  I have been using DiAdem 11.1, and have not looked at the new features of 2010 yet.  The new idea...use LabVIEW code to make scripts.  I know LabVIEW very well, that is how I make the TDMS files; but the idea of data analysis or automation comes to a standstill when you tell me I need to learn VB to manipulate or work with the data I just gathered beyond the canned toolsets already in DiAdem.  DiAdem needs to be like Teststand in this regard.  You can use different code types with Teststand, and it works.  And this needs to work in all the different categories of scripting or automation (Navigator, View, Analysis, etc.)  Any software package NI creates should have LabVIEW as the center point, and always require seamless integration of LabVIEW code.  I think that comes down to plain-jane good marketing strategy.

I do not understand why it is not possible jet. After I Drag and Drop a Waveform inside VIEW. A possibility to change the x-Axis to absolute time should be possible.

The only way of doing it now is creating an extra Time Channel.Smiley Sad

Please include commands to handle INI Files (like CVI)

 

at the moment we have to handle and search for goups completle manual

 

it would be much more easier to get 1 command to geht the Value from "test"

 

[exam]

test = 3

 

Rather than asking for a change to the "Repeat Marker" to plot all the points (we'd prefer "Repeat Marker" in DIAdem VIEW to be "Every N Points" where N = 1 rather than "Up to N Points" where N = 100), I think it would be great if we could have a configurable DIAdem default set of VIEW items that could be saved via usercommand, script, or a file configuration so we could conveniently spread it to our users.

This could include colors, points and/or lines, "Repeat Markers" configuration, line width/size/fill.

 

The "Repeat Markers" option is the most important to us because we have had users in the past who didn't realize that they were only seeing 100 points of their data, which can be a very bad thing (for example if you've turned off curve color and are looking for outliers in 150 points of data).  On the other hand, I can understand not wanting to plot 2 billion points on a graph, hence the ability for an administrative body (or individual users) to configure the graph defaults.
