I use Vertical Linear Scale control as Bar control
Min = -50 and Max = 50
by timer i get values and each tick the bar is filled till the value that came from -50 till the value
but I want that the start value to fill the bar will stay 0
For Example: if I will get value = 20 I want the bar will be filled from 0 to 20
and if i will get value = -20 I want the bar will be filled from -20 till 0
Thanks
