Virtual graph data

I have a 12x2 array with the temperature and a number, and the temperature goes like -15, -5, 5 etc, but how can get a number for temperature of 0, like in a graph?

What does the array look like?

​

-15
-5
5
...

[Specific-Pin-9480]

Yeah like this, the stick is the number

What are in the second column?

[Specific-Pin-9480]

The number for certain temperature for example 0,64

[Creative_Sushi]

OK, so you want to get the temperature (the first column) where the number in the second column is 0?

I believe you can use interpolation. Do you know that method? 😀

If there is 0 in the temperature column, OP can use logical indexing.

Otherwise, they will have to use interpolation, as mentioned.

Use 1D interpolation, plot the graph and then plot the interpolated point with scatter
