How would I create an interactive component similar to the Locator functionality provided in Mathematica? For example, the command in Mathematica

Manipulate[
  Graphics[Polygon[pt], PlotRange -> 2],
  {{pt, {{0, 0}, {1, 0}, {1, 1}, {0, 1}, {1, -1}}}, Locator}
]

creates five Locator objects stored in the variable pt. This example can be found in the

Hi! I need help with my project I dont know where to even start!

Question:

Consider a simple polymer , which consist of long chains of simple molecules attached to each other, e.g:

....-CH₂-CH₂-CH₂-...

If the interaction energy between consecutive sections ca be ignored or is low enough, the chain can be bend around at varios places to form varios configurations. One can start by  fixing the first section...

Hi everyone,

Is it possible to perform an integral over vector without writing a multiple integral over each component?

I am integrating over a vector of dimension 12, so I am trying to find another way to calculate rather than writing 12 integrals.

Thanks

Firstly applogies for if this question has been asked before.

I am trying to plot a simple epidemic model for where I can change the rates.

My equations are:

de1:= diff(X(t),t)=a*X(t).Y(t);

de2:=diff(Y(t),t)=a*X(t).Y(t) - b*Y(t);

where X is susceptibles and Y is infected.

I would like to be able to produce a graph with the susceptible and infected plotted. Where i can change the initial conditions of X(0) and Y(0) using sliders...

hi

I am a mechanical engineer student and i am trying to learn mapleSim, but i am having some dificulties.
I am first trying to model an heat exchanger from a domestic water heater. I have found on maples website a costum component and i am trying to do a similar one to start.
The component that i am talking about is this one:

The problem is that after i put my own equations, parameters,...

Is there a way to create an interactive plot, and put it in a Maplet, so I could get onclick coordinates and display some points there on my plot ? I checked Maple help and I didn't find any onclick event for plot or Maplets,Elements,Plotter but I found something called PlotComponent and there are some options like clickx, clicky. Can I use it somehow in Maplet, or maybe there's another solution ?

To insert a component on your worksheet you need to drag it out with the mouse.  Is there a way to create a slider, for example, on the worksheet without using the mouse? 

Am i undestand right that all GUI-changed properties of plot are not accessable via command-line because with already pictured plot there are no binded variables and no method to bind? For example after manual streching and moving i need to work in interest area of graph i.e. includding new textplots there and so on. See only way to work with via DocumentTools component and it events to get e.g. xrange  and yrange. Is there better way?

Don't forget set Plot0 component manipulator to "Click and Drag" to test "on click" event. Localizing of problem takes for me ~4 days. It's terrible!

How to change font for TextAreaComponent? Size of symbols by default are too small :(

How to change 'Data table' component column width? Is it somehow related to width of data table, to which this component connected?

I want to have a Plot component display animations, controlled by a button. I want each click
of the button to show a new animation.

So e.g. the Action when Clicked for the button might be something like this (for animations alternately in blue and red):

use DocumentTools, plots in

if cc = red then cc:= blue else cc:= red fi;
Do(%Plot0 =animate(plot,[sin(x+t),t=0..Pi,colour=cc],x=0..Pi,frames=4));
SetProperty(Plot0,play,true,refresh=true)

Hi,

How can I model a ground pattern, like was done in the demos of the planetary rover (http://www.maplesoft.com/products/maplesim/demo/OrangWowMoment.aspx)?

I see in the block model of the planetary rover that there is a component called "ground pattern" and it is not connected to any of the other components of the model, and this component is also not part of any default libraries of Maplesim.

I am creating a maple document to display the tangent plane to a function. the resulting function and tangent plane are displayed in a plot component. The problem I am having is that I can display both the function and the tangent plant at the same time with the foloowing statements:

PlotSurfs := plot3d([Func,TanPln], x = Xo-DmX .. Xo+DmX, y = Yo-DmY .. Yo+DmY,axes=VarAxes,scaling=VarScl,orientation=[OrX,OrY,OrZ]);

 DocumentTools[SetProperty](PlotWin, value, PlotSurfs);

Is there a way to select multiple entries in a ListBox component?
