I am trying to make a dialog with manipulate like this: If[ DialogInput[ Column[{"Go on?", ChoiceButtons[{DialogReturn[True], DialogReturn[False]}]}]] == True, DialogInput[{Row[{TextCell[ " Value of b "], TextCell[" …

I would initialize the values of b and c with a DynamicModule: DynamicModule[{a, b = 1, c = 1}, If[DialogInput[Column[{"Go on?", ChoiceButtons[{DialogReturn[True], DialogReturn[False]}]}]] == True, DialogInput[{Grid[{{"Value of b", "Value of c"}, {InputField[Dynamic[b]], Inp…

Laurens, First, you should read the posting instructions. It really helps if you post code using the code sample button. Your code has several problems. No need to use Show, There are extra brackets around Pi (because of the way you posted the code), Gianluca fixed these in his code. Here is an…

Also, Note that you do not have to use a dialog for b and c – you can always add them to the DynamicModule so they are dynamically adjustable along with a, (Have one slider and two dynamic input fields for b and c. DynamicModule[{a, b = 1, c = 1}, Panel[Column[{Row[{InputField[Dynamic[b], Number]…

Thank you Gianluca and Neil for your help. The first solution of Neil does the job I need. The other two give for b and c with each new run the start values, i.e 1 and 1. I want them to keep the values of the previous run though. I did not know the existence of the function NumberQ. That one really …

The last, short example can be combined with the other to create the “retention” benefit for b and c: DynamicModule[{a}, If[! NumberQ[b] || ! NumberQ[c], b = c = 1]; Panel[Column[{Row[{InputField[Dynamic[b], Number], InputField[Dynamic[c], Number]}], Slider[Dynamic[a], {1, 10}], Dynam…

Dear Neil, I very much like the solution you presented in your last post, since using this I would be able to add several controls for other parameters. But it does not seem to work for plotting an accumulation of random numbers, like in: Panel[Column[{Row[{Slider[Dynamic[seed], {1, 100, 1}], Dyna…

I am sorry. The first code should have been: Panel[Column[{Row[{Slider[Dynamic[seed], {1, 100, 1}], Dynamic[seed]}], Dynamic[SeedRandom[Dynamic[seed]]]; Dynamic[ ListPlot[ Accumulate[RandomVariate[NormalDistribution[0, 1], 200]]]]}]] It makes no difference in the output though. The problem remain…

You should put the SeedRandom and the generation of the points in the same Dynamic so they are run together. Dynamic is smart about execution and will only run if it sees that something inside changes. It is not aware that changing the seed affects the distribution which does not necessarily need …

Thanks a lot Neil for your advice. I have also studied the code with the interval slider that you referred to. It took me some time to understand the working of the two pure functions, but I think I finally did. To test the code I had to find a replacement of the financial data, since these are unf…

Laurens,

You may also want to also consider setting the PlotRange manually so the axes do not bounce around. You might benefit from looking at the code I posted here for another forum question .

Regards

Neil
