Sum values from array, then take percentage.

[Lycle]

New to labview this is probably really simple but I am hitting a road block.

I am using a DAQ device to read in 3 values continuously.  I want to take these three values and get the percentage of each one from the total, the output to a graph the %.  I'm not sure how to get the sum of the values from the array.

For example:

Value 1 = 7

Value 2 =5

Value 3 = 8

Sum = 20

Value 1 % = 35%

Value 2 % = 25%

Value 3 % = 40%

Thanks for any help.

Add Array Elements

This should do the trick. Instead of the 3 random numbers, substitute your inputs. Even better, send the array of inputs directly into the "sum array" input wire.

Why do you index the array instead of just plugging it into your divide?  You'd get the same result.

 That makes very little sense.

 How should the graph look like? Do you want to chart the three percentages over time forever or do you only want to see the current three percentages?

If you want to chart the three over time, you could do something as follows:
