Can sliders control points on a XY Graph - Please help.

Good morning LabView Forum,

 

The aim here is to have eight sliders (Vertical Fill Slide) to control the positions of 4 points on a graph. I want the graph to control a stepper motor's Ramp Up, Move and ramp Down.

It is very easy to see I'm just starting out with LabView, so my ideas could be a bit off and could point in the wrong direction. I'm trying. I'm an artist so it makes sense.

 

Currently, I'm changing a working system where a simple Knob is used to control a Graph and the motor. This works well and the Slew control does its stuff! An image of the .VI is below.

 

As always I will attach the files.

 

Please help.

I worked it out eventually. Lots of YouTube watching. I'm learning.

Hey there,

I see you seemed to have worked it out. I'm unsure how you went about it, but I thought I'd put up an example of how I would have done it from your initial image. If you build the slider values in to the two arrays for X and Y values that will allow you to control each point individually.

 

Hope this helps!

Hello Nic,

 

Thanks for the help!  

 

I am learning slowly. It is hard when you don't know something and 20 helpers come along and they tell you 10 other things you don't know or understand. ;o). It takes time to piece everything together.

 

I would like to see your VI file, but it's for a later version. I'm on 2014 home student.

 

I am making good progress and want to learn more.

 

I got this working by taking bits from other topics and stitching them together.

 

Please keep helping! I am 54 now and learning is slower.

Apologies!

 

I took a stab and saved it for 2015, wasn't quite enough. Here it is for 2014.

Yes! That is what I was trying to do.

 

I will work with that and play!

 

Many thanks again!
