Read values from plots

[BT_10780541]

How can I add cursor to read the values from the plots it is possible in prime 10? Or any other method ?

Cheers,

We need more info.

Is the plot created in/with Prime?

Attach the Prime worksheet that contains a/the plot.

Do you want the cursor, or just the data,,?

Success!

Its kind of general question I have. There are plenty of plots in my worksheet just wanted to know if there is a way to add cursor to read values from the plots

If I understand the request correctly, you want something like this?

(This uses Horizontal and Vertical markers where the vertical marker is equal to xvalue and the horizontal marker is set equal to xvalue². xvalue can be slided with the Slider control that goes from -10 to 10. Doing this changes the location of both markers)

I guess you are talking about a "trace" facility like the one we had in real Mathcad.

Unfortunately Prime does not provide anything comparable.

The workaround provided by @DJNewman  looks similar and is a nice idea, but of course is much more uncomfortable and labor-intensive. Especially when you think about hopping from one plot trace to another or when you think about plots of functions in parameter representation. It sure can be done (the slider could change the parameter instead of the x-value) but it means to hav eto invest quite some work and you end up with a slider reacting very slow and tenacious.

Here is an attempt in P10 following the idea presented by @DJNewman .

I won't claim that its a satisfying and convenient solution, but ...

Very cool incremental improvement.
Question; in the hidden area you use a -x- notation in your definitions. What does that mean/do?

Using -x- and also -f- and -ff-  was just an attempt to choose variable/function names that are highly unlikely to be used in a normal sheet, as names containing a minus sign cannot be generated by normal means.
Doing this was quite unnecessary here in the demonstration example and was also counteracted by the introduction of the TraceXY vector. 😉

Actually I introduced TraceXY because I thought that the labels in the markers could not show more decimals (they could using the normal math format) and so I would be able to show the 'cursor' position with more precision. It was just later that I realized that it was the slider which only provides coarse values and I found that using the Slider.TickFrequency(...) method allowed to use a more refined grid of values then the setting in the properties tab. Unfortunately this does not help much because the slider reacts very slowly and imprecisely. Wish this could be improved and that we could move the slider using the keyboard in much finer increments.
