Can I use LOOKUP SLOPE to access point to point slopes as rate data?

[tc20852]

Hello Everyone,

Here are some Kinetics based data input as a lookup "RawDataLookupTable".

the problem is that point to point slopes must be available as input for a rate between two stocks in a larger model. See png of the graph of the output to "gradients" that I am trying to achieve.

I've tried using LOOKUP SLOPE but this is not giving me what I want. See screenshot of an excel graph.

Thoughts anyone?

I think the reason you're not seeing what you expect is that your model time step is 1, so you aren't evaluating any points that are in between the data points.

Make time step << 1 and you'll see something like the gray line.

Oh, I had to restart vensim. When I went back to look at my original problem, the lookup slope worked great.
see attached.

I think the key difference here is that time step = .015625.
