I use this Manipulate in a package:

Manipulate[Plot[Sin[a1 x1], {x1, -2 Pi, 2Pi}], {a1, 1,5}, Text["y=a1 sin(x)"]];

In the notebook, near the slider that is created, there is Pack Private a1. How can I write something istead of that? Or just a1?

Manipulate[
 Plot[Sin[a1 x1], {x1, -2 Pi, 2 Pi},
  PlotLabel -> "y = sin(a1 x)"],
 {{a1, 1}, 1, 5, Appearance -> "Labeled"}]

  • $\begingroup$ @BobHanlon I mixed you solution with the Shadowray one: Manipulate[Plot[Sin[a1 x1], {x1, -2 Pi, 2 Pi}, PlotLabel -> "y = a*sin(x)"], {{a1, 1,"a"}, 1, 5, Appearance -> "Labeled"}] $\endgroup$

You can add any text label for Manipulate parameter like this:

Manipulate[
    Plot[Sin[a1 x1], {x1, -2 Pi, 2 Pi}], 
    {{a1, 1, "my label for a1"}, 1,  5}
    ]

This method does not depend on the $Context and will show the same label even when called from package (i.e. when your variable is called Pack`Private`a1).
