I just want to see dynamic evaluation inside manipulate. I have long equations inside manipulate. And want to see dynamically my listplot. I make simple example. But i see only dynamic controls, but not results of equations.

Manipulate[{Dynamic@x, Dynamic@y}, 
 Grid[{{Control[{{x, 0, "x="}, 0, 1, .01}]}, {Button[
     Text["Run"], {y = 0; f[]}, ImageSize -> 100, 
     Method -> "Queued"]}, {Dynamic[
     ProgressIndicator[y, {0, 1}, ImageSize -> 100]]}, {Dynamic[
     Text@Row[{Style[y*100, 11], Style["%", 11]}]]}}, 
  Spacings -> {0, .3}], {{y, 0}, None}, 
 TrackedSymbols :> {x},(*does nothing,just for testing*)
 SynchronousUpdating -> False, SynchronousInitialization -> False, 
 Initialization :> (f[] := 
     Do[Pause[.15]; y = i; 
      x = i, {i, 0, 1, .01}] (*Pause[] to slow it down*)])]

How can i see dynamicaly updating {x, y} or listplot inside of manipulate body? Thx.

  • $\begingroup$ The shortest way is to use stupid Dynamic@First@List@y because there is a bug which makes Dynamic[y] less sensitive than it should be. $\endgroup$

  • $\begingroup$ Dynamic@{x, y} or {Dynamic[x, TrackedSymbols :> {x}], Dynamic[y, TrackedSymbols :> {y}]} instead of {Dynamic@x, Dynamic@y} does update as expected. $\endgroup$
