HELP with Interpolate vi

[AmeHyesung]

Hello everyone our project is now facing a problem in LabView.

We need to build a function using the labview that could output a dependent y value when input a independent x value.

eg. when get 6.7 from NI 9263, output should be 100 for further education. When get 6.1, output should be 50...

I've already build two arrays for my X, Y value,  I try to use Spline Interpolate vi , Interpolate 1D vi, these two functions.

But when use Spline Interpolate, the indicator for y value is 'NaN'.

When use Interpolate 1D, the indicator for y even doesn't show anything....

I attach our two programs here. Could anyone help us with it?? Or could you give us another way to solve it!!!!

Really Really thank you!!!!!!

Do you have some data that we could play around with?  The best way would be to put the data into your arrays and run a couple of loops.  Then go to Edit->Save Current Values as Default.  Then post those updated VIs.  I don't see anything wrong with your code, so it must be something in the array data.

Sorry too late to reply tou!!!!!!

 Our data in the array are:

Voltage,  SOC

12.7,        100%

12.5,         90%

12.4,         80%

12.3,         70%

12.2,         60%

12.1,         50%

11.9,         40%

11.8,         30%

11.6,         20%

11.3,         10%

10.5,          0%

We only want a singl SOC value fot futher calculation. I try some other ways but they give arrays....

Thanks Very Much!!!
