# manipulate with Plot

Facing problem with using manipulate along with Plot. Below is the function call where I have only one parameter to change, hence plot is not allowing. Searched for various options but not able to achieve manipulation

curve = Manipulate[ParametricPlot[abc[b, n, 0, t], {t, 0.7, 1.2},PlotStyle ->
{Thick}], {{t, 0, "max"}, 0, 1}];


Need to manipulate as per t value. Not able to get the correct syntax.

• Including the definition of abc would be nice… Feb 16 '16 at 6:46
• Have you seen Manipulating multiple parameters in a ParametricPlot?

You can't manipulate the t of your plot function.

Try this

curve = Manipulate[ParametricPlot[abc[b, n, 0, t], {t, tStart, tStart + tPlus},
PlotStyle -> {Thick}], {{tStart, 0.7, "start"}, 0,
1}, {{tPlus, 0.5, "plus"}, 0, 1}];

• throws error as ParametricPlot::plld: "Endpoints for t in {t,FEtStart$$2779,FEtStart$$2779+FEtPlus2779} must have distinct machine-precision numerical values. " Feb 16 '16 at 7:17
• Yes, you shold not try to use an exact zero. Try the edited one, where the starting values aren't zero.

• \$MachineEpsilon` is handy for that sort of thing. Feb 16 '16 at 8:40
