Maybe, I have a great idea for the DateTimeAxis – TimeSpan.
I know about the DateTime and TimeSpan axes and would be happy about a feature that brings them together.
The idea is to have <DateTime, IComparable> data on a DateTimeAxis and assign a mutable reference DateTime on the Axis. Then, the Axsis can show the time span between the reference time and the data point.
I don’t have a screenshot of an ui with that feature. I need to change my application anyway to display the measurement relative to the trigger as timespan. But from now, I am on my first steps to that goal 🙂
Maybe, I can give you a better impression with some sample images.
We do weighing with high performance weigh cells. The app connects to the device and can display continous real-time data.
[see image: continuous]
In that use case, DateTime-Axis is needed.
In “productive” operation, the cell continously weighs products. The operator can see the measurements on the plot and have a overview of the process.
[see image: multiple]
When the operator needs to setup the device, he needs single measurements and look for the setup- /rise- /fall time of the measurement. For that, a trigger signal is send to the app and the plot sets its VisibleRange to the trigger possision.
[image: single ]
Now, the operator needs to see the data points in relation to the trigger point (not yet visible on the screen) which is located around 15:41:44.
My idea is, that I can set (and clear) a reference DateTime value on the XAxis which, in my case, is the position of the trigger event and have all the XAxis rendered as a TimeSpan.
Similar on an ordinary scope you have:
[image: scope] where you can see the trigger position indicated as a small black arrow on the top. Now, think about how sweet it would be to have a TimeSpan-XAxis on that scope and than zoom out of that single shoot to smoothly go other to the continous data acquisition.
