It would be fantastic if you would develop your own, or put a wrapper around one of the existing public domain, statistics packages and greatly expand on the statistics currently offered in the product. Evaluating the statistical significance of data seems a natural and powerful feature that should be included as part of data analysis.
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.
I've noticed that the easiest way to relate a channel calculation back to the original channel is to append to the channel name:
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...
I quite often use a 2nd y-axis in a 2D-diagram. In order to improve the visibility I like to use the same grid for the first and second axis but different scaling. The 2nd y-axis is set to automatic scaling because of changing data ranges. Unfortunately the scaling range used for the second y-axis is completely unpredictable. Therefore the scale is way to big and the setting has to be corrected manually. This is very annoying, because the automatic choice is often not very logical and this behavior is not documented at all.
I work with a lot of data that contains true/false parameters. I spend a good amount of time converting these channels to 0's and 1's in order to plot them with other numerical parameters. Excel will automatically plot true/false parameters as 0's and 1's, but I prefer to use DIAdem. It would be very helpful if DIAdem could plot these without converting them.
I can't rotate graphics or rectangles, ellipses etc. in the diadem report (display-position-...?). This is however possible with text boxes and should be no big deal for other object or graphics
When developing scripts, I frequently add channel groups for analysis results, using
However, when re-running the scripts, successive groups "analysis1", "analysis2" etc. are created. This is a handy feature that I should not want to miss at some times, BUT
at other times I want to skip the creation of new channel groups. As a work-around I litter my code with 'exist'-statements such as
If not call data.root.channelgroups.exists("analysis") then
Set oResGrp = data.root.channelgroups("analysis")
Now, my suggestion is to add a command such as "AddOrReplace" or "Use", which would use the existing group if it exists and creates a new group if not. Pretty much the same behaviour as with the calculator, where
CH("NewChannel")= CH("oldChannel") will create a new channel or overwrite an existing one.
would work as we know it and
would create a new object or use the existing one.
Alternatively one could supply an optional paramter to the .Add-method like
as default using the well-known behaviour whereas
would change to create or replace.
Obviously the same would come in handy for channels or other objects that use an .add-method.
Having network directories available in the DataFinder is a great tool. However, if a network directory is added as a default search locations AND the network cable is unplugged, DIAdem will hang for a very long period of time. Windows commands are used to query for network locations. If not connected to the network, the timeout for these commands is quite large.
While this is technically expected behavior, it is not ideal software functionality to hang if a network cable is unplugged.
I would like to be able to copy a plot to the clipboard, either from View or Report. At the moment I have to use a screen-capture tool like Snippy.
I am introducing DIAdem to our company at the moment and all my colleagues are surprised that DIAdem cannot do this.
This idea is another idea borrowed from programmers editors, the idea being to show a search history window that will show all matches for a specific term. If the particluar line is double-clicked then Diadem will jump to that specific file and line showing the search term.
I would like to be able to view the date of a time channel in a 2D Axis System. I know I can do it transfering it to DIAdem REPORT and then selecting the desired format in the axis, but I want to do it on VIEW.
I have tried with a waveform channel, a channel made of time stamps... I think it would a great feature!!
When dragging and dropping a channel into a View or Report table from the Data Portal, no matter where you release the channel, it's always appended to the end. This can be frustrating if you have a large number of channels in the table, forcing you to rearrange the table after each channel is added.
I would like to propose the ability to drop channels in-between columns of the table, OR append channels on the end.
I would think that the area you drag the channel into would decide where it inserts:
Between 2 channel headers (anywhere in the "Selected Channels" section or above) = Insert
Anywhere on the "Channel Contents" section, row numbers, or blank area without channels = Append to end
In Report it's possible to create a 3D matrix plot with only an Y-axis and the X-axis embedded in the waveform channels.
If you export this to VIEW this won't work since VIEW needs an explicit X and Y channel.
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.
Add the ability to decode relative paths for video files within View and TDV files AND make it the default setting. Adding an option box to the "Select Video File" dialog to allow absolute or relative path decode. Also have the system recognize a relative path (i.e. ".\video.avi"). This may require a new TDV-Path variable. This allows moving large video/data views to networked based folders allowing other engineers/customers to review/manipulate the data.
When I export a plot in a DIAdem report I lose the transparency that I have associated with any coloured background segments in my plots. It would be helpful if the transparency was maintained as it helps to show overlapping areas.
As a side note, I find that when I zoom out on the axis of a plot the background segments disappear when they get narrow, but still wide enough to show on screen. This can be confusing as there is no indication it is happening. Perhaps background segments could always be drawn at least 1 pixel wide.
What I am missing in the DIAdem VIEW Map option is the start point and end point of a plotted trip in the DIAdem VIEW Map option.
It would be nice to have this option like it is in Google Maps and even better if this is possible for multiple trips (for instance with the option to use/select the engine speed as an input value to divide the different trips in case of merged data). See the attachement for an example!
The DIAdem R&D team is committed to reviewing every idea submitted via the DIAdem Idea Exchange. However, we cannot guarantee the implementation of any DIAdem Idea Exchange submission until further documented.
