Hi folks!
My project needs some agile experimental frontend to find some factors for an equation, such
# example equation
weight_1 x value_1 + weight_2 x value_2 + weight_3 x value_3 => total
What I need is that each value_X lay between 0.0 and 1.0, but they are related with others.
The constraint is: weight_1 + weight_2 + weight_3 = 1
So, Is there any alternative to use N sliders (1 per weight) as well they sum up 1 ?
the “equation” is a weighted average 
I couldn’t realize how relate all weights.
Thanks!
