Colored plot of a parameter with coordinates not homogeneous

I have a txt file as follow:
X Y Parameter
1.1 0.5 324
1.2 0.7 4222
1.5 1.1 425
2 1.11 5
My file is bigger, but it's just an example. I would like to rapresent in a X,Y plot the value of "Parameter" with a colored scale. Since the interval between coordinates is not constant I don't know how to rapresent it. Can anyone help me?
Thank you!

You can use textscan(), readtable() or importdata() to read the values into the workspace.
For plotting in different colors, scatter() would make sense.

"If you want to fill the space in between the scattered points, you would need to perform some kind of interpolation."
Yes, this is exactly what I need. Sorry I didn't explain it properly.
