Trend View Feature Requests

[Controls Guy]

1) Have a real-time value display at the margin for the cursor X and Y, so you can accurately measure arbitrary locations on the trend graph (this is different from the dialog that displays if you click)

2) Allow full expressions (or at least Y-offsets) for the pen definition.  This is useful when you're tracking two items that are mostly equivalent, but you want to compare them, like an analog and a filtered version of same.

3) Lose the confirmation dialog, at least optionally, when the user deletes a pen.

4) Is it possible to choose other than time for the X-Axis?  This may already be there but is sometimes very helpful.

5) Was the UDT member-name length limit increased in v2.5?  I just added some members to a UDT and expected to hit the limit but did not.   If so, kudos!

I think #1 is already done - look at the application status bar, left side.  it updates as you move the mouse cursor.

#2 - we already have the idea of supporting scale of Y in the form of Ynew = MYold + B or even Ynew = log(Yold)

#3 - easy peasy (checkbox)

#4 - not sure what you mean.  The data is streamed as time.  Give me an example of another X axis.  Are you wanting a statistical histogram or

#5 - I'm going to guess yes - it was probably an easy fix, it was never entered into FogBugz.  What exactly was the issue?

1) Yes, exactly.  Thought of checking the status bar, but didn't look far enough left.

2/3) cool

4) Comparing two process variables to see how they relate.  Sin(something) vs. Cos(something else)

5) No problem.  In fact, was expecting a problem and didn't encounter it.  Was just saying thanks if the member-name length limit had been increased.

Still not understanding #4.  Are you wanting to just plot points, over time, Var 1 vs. Var 2, so NOT a trend view but a Cartesian graph?

T, R0,R1

T0, 1.0, 1.0
T1, 1.0, 10.0
T20, 2.0, 10.0
T21, 2.1, 10.0

So you just want an X/Y Cartesian plot of points at (1.0, 1.0) (1.0, 10.0) (2.0, 10.0) (2.1, 10.0) without any concept of time?  As an X or Y value changed, just plot the new (x,y) point?

[Controls Guy]

Correct.  And there should probably not be a line connecting consecutive samples, but just a collection of points.  Then the locus of the sample points makes it's own line.

You can do this using Trend View Export and Excel today.  Since you don't care about time, it would be historical data anyway.

But the export contains time stamps so you COULD even take into account time using Excel's data analysis tools.  Trust me, they can do WHATEVER you think you want Designer should do - and do it today.  :-D

Here's a sample CSV export:

Excellent point!  Non-time graphing is a very useful tool (when you need it), but that need is infrequent enough that it's probably not worth stealing time from other development priorities, especially since there is a way to get there anyway.

3) Lose the confirmation dialog, at least optionally, when the user deletes a pen.

Fixed in Designer 2.7
