vi for quadrature detector

[manuuu]

Sir/Madam

I am having four sensors producing datas and i am collecting them through the serial channel of my pc.

I want to display an indicator in a graphical plot. If all the four datas are equal then the indicator should

be at the centre and according to the datas coming from the sensors the indicator should move.

please suggest me what kind of plot should i use and say something about how to implement this.

thank you in advance

manuuu

Three solutions are coming into my head:

1.

Use any control elemtent and put it on top of your graph. Move the control elemtent around by using the property node position.

2.

Use a waveform graph or xy-graph and a cursor. Move the cursor arround using the property for the active cursor and its position.

3.

If the background is a real world graphic use the picture functions. Use the graphic as background and draw the indicator in front of it.
