Creating a 2D temperature plot

I have an array with 16416 x-coordinates, another array with 16416 y-coordinates, and a third array with corresponding temperature values at each of the x and y coordinate pairs. Each array is the same length.

For example, x = [0.22400, 0.27570, 0.32790,...], y = [-0.0097810, -0.012040, -0.014320,...], temp = [660700, 445800, 443500,...].

I would like to make a plot colored according to the temperature at each point, similar to this one:

I cannot seem to find an easy way to interpolate the data. Any suggestions? Thanks so much.

Use griddata. It's the easiest way
