Trend View Feature Request

If possible, have floating tags (or dedicated area of screen) showing current value of all trending elements based on cursor position. This would allow display of values without having to left click to "snapshot" element values.

Already does that.  Move your mouse cursor to the point you want to know.  Look at the status pane of the Trend View.  It gives you the Time value and the Trend Value at the mouse cursor position.

I guess I might be missing something. I only see in the bottom left corner of DmD the time and cursor position in the currently active pane. What would be nice is if there was something that displayed all trace values at the horizontal position of the cursor across all trending panes as the cursor is moved around. Are you saying it already does this?

I think what you are wanting is a very responsive query against time as you move the mouse cursor.  It would not be very responsive.  The mouse cursor movement would constantly be querying against a database that is also constantly being written to.  It would slow down both.

It may be useful in Historical Mode.  We could implement it for Historical Mode then see how bad it is when it's "live".

Historical mode would be sufficient for me without having to have it in live mode.

As an additional feature in regards to the trend view, would it be possible to log to a .trarc file using the FILELOG command? It would be nice to be able to use the command to log to a .trarc file so that it can be recalled using the Open Trend Archive for quick data analysis.

Importing a FILELOG text file would be easier.  Good idea.

Another nice to have would be the ability to temporarily turn off the view of a specific trending element in the trend view. For example, if R0 is an unfiltered value and R1 is that value with filtering it would be nice to be able to toggle the view of R0 off. If both are plotted on the same trend the noisy R0 obscures the ability to really see R1 well but having the ability to view both on the same trend is also useful. This is one example but I can see it being useful for other scenarios as well.

FYI, in the Trend View Options dialog, the order of the specific elements in a Pane affects the order in which they are drawn.  Hence, you can prioritize the drawing by using the Move Up and Move Down buttons of the specific elements you want drawn on top of other elements.

The first element in the list is drawn last (on top of everything else), so move elements you want to "hide" DOWN the list.
