Increment and decrement buttons to change dial knob numeric control value

[msabah38]

I have a numeric knob with values { 1, 2, 3, 3.5 ,4, 5, 6, 7, 8, 9, 10 }. I have two buttons, one for increment and other for decrement. 

Using these button I need to change the knob values. Kindly help.

Hi msabah,

your VI does exactly what you have programmed to do!

Why do you use "Scale.Increment" when you want to change the knob value by exactly "1"?

Why do you subtract the current value from Increment in the "decrement" event?

Why don't you use AutoCleanup?

Why is there a "default if unwired" tunnel?

Why is there a timeout event which is never executed?

Since in the knob after the value 3, it has to increment to 3.5. I wanted to use a property node which knows the difference between two pointer values in the knob. 

In the front panel when I drag the pointer of the knob it properly changes from { 1,2,3,3.5,4,5,6,7,8,9,10}. 

How to change the knob pointer using property node to the next pointer?

Hi msabah,

I would solve it like this:

In general I would not use a knob here, but an enum or ring…
