Hi, > just a simple question related to Manipulate[] - is there a way how to access the values set by slider in Manipulate? > > For example, I have the following code: > > m = Manipulate[ > ListLinePlot[{ > data, > {{xmin, 0}, {xmin, 100}} > }], > {xmin, 1, 10} > ] > > and after the user sets a value 'xmin', I would like to read it out. How? It really depends on what you want to achieve, but the most simple solution is to just set a global variable within the Manipulate: Manipulate[ parameter1 = n; Plot[Sin[n x], {x, 0, 2 \[Pi]}, Frame -> True, ImageSize -> 400], {n, 0, 1}, ] whenever you now access parameter1 it will have the value that is shown in Manipulate. To refer to your other question, you can also make e.g. a modal dialog which returns that value like so: newvalue = DialogInput[DynamicModule[{parameter1 = 0}, Column[{ Manipulate[ parameter1 = n; Plot[Sin[n x], {x, 0, 2 \[Pi]}, Frame -> True, ImageSize -> 400] , {n, 0, 1}, AppearanceElements -> None ], Button["OK", DialogReturn[parameter1]] }]] ] hth, albert
