Problem in using preassigned variable in manipulate

[Pooja Tewari]

Hi,

I am new to Mathematica and I have been stuck with this seemingly small issue for some time now -

x:=.5;

g = Manipulate[
Plot[Sin[i t], {t, 0, 10},
ImageSize -> Scaled[x]], {i, 1, 5}]

I want to assign the variable x to .5 and then use it in Manipulate function, which plot a graph of sin[i t] and imagesize should be scaled to x( which is already assigned). But when I am deploying this in cdf, I am having this error

"The specified setting for the option GraphicsBoxOptions, ImageSize cannot be used."

[John Fultz]

There are several ways to do this. In this case, I would use With:

With[{x=.5}, g=Manipulate[=85]]

This literally substitutes .5 into the resulting expression before it's
evaluated. Another common possibility is to assign it to a
DynamicModule variable, which will remain present and properly
initialize in the resulting CDF:

DynamicModule[{x=.5}, g=Manipulate[=85]]

Sincerely,

hello,

your cdf file does not store the definition for x in your case.

Use therefore

g = Manipulate[
Plot[Sin[i t], {t, 0, 10}, ImageSize -> Scaled[x]], {i, 1, 5},
Initialization :> {x := .5}]

or use

x:=.5
g=Manipulate[Sin[i t], {t, 0, 10}, ImageSize -> Scaled[x]], {i, 1, 5},
SaveDefintions->True].

to safe any definitions associated to expr.

Best,

Christoph

I missed the "deploying this in cdf" sentence, so my original response
is irrelevant.

Your code works perfectly as is for me (Mathematica 8.0.4).
f[x_] := Manipulate[
Plot[Sin[i t], {t, 0, 10},
ImageSize -> Scaled[x]],
{i, 1, 5}]

You can even make a function with x as argument:

f[x_] := Manipulate[
Plot[Sin[i t], {t, 0, 10},
ImageSize -> Scaled[x]],
{i, 1, 5}]
