Virtual joystick pointer to follow picture of shape

[alanled]

I have a virtual proportional joystick which controls a two hydraulic cylinders in a xy format ie both cylinders 50% extended is the x0 y0 position(park position). I can manually control the cylinders but I would like to create....say a circle or any closed shape and have the joystick pointer follow the preselected shape automaticlly with a speed control. I was wondering how to do this, mybe using some kind of corrdinate control. Many thanks for any help.

Could you please post some images to help illustrate your request?

I may be able to offer advice if I had a better idea of what you are after.

I have a picture frame with a pointer dot in the centre that can be dragged with the mouse pointer anywhere within the picture frame outputing 2 values for x and y axis i want  the dot with the use of a start/stop pushbutton to follow any shape i place in the picture frame or have a pre-selection switch with square, circle etc. So, in other words when I press start the dot will follow the path of the circle outputing the x and y values.

Again, a picture would help me follow you.

As it stands it sounds like you want a dot to move along the path defined by an object in the picture control. Is that correct?

Since I am not sure if I understand your request let me share a link to a thread where I have been gathering links for Picture control threads. Reply #27 of that thread has an embroidery example that may be helpful.

Please forgive me if I am not helping,
