How to plot this graph?

Hi everybody, I want to do plots like this one:

I have a set of 1500 data points (as shown in the figure). Each one has a different value, like a 'Z' coordinate (for this reason each of them has different colour):

3.20517	3.19289	-1.52965
3.19289	3.19462	-1.52965
3.19462	3.20517	-1.52965
3.20517	3.20885	-1.52965
3.20885	3.18635	-1.52965
3.18635	3.19622	-1.07372
3.19622	3.18359	-0.84327

[SL: snipping the rest of the (several page long) data set. Showing a few points is suffficient to show what your data looks like.]

Where the first column is the x-coordinate, the second one is the y-coordinate and the third column is the value of the desired colorbar (different to the original figure)

How can I plot this? I tried with the contour function with no results, may anyone help me out?

Many thanks in advance,

Regards

doc scatter

I think it's not a scatter plot, it seems a contour plot, but I don't know how to do it

[darova]

Did you try scatter?

[Juan Castillo]

Yes, and it works:

But if you look very close to the first graph, there are no points, no spots, it seems like a "little surface", so that makes me think about a contour plot, but I dont know hoy to do a contour plot with 3 columns

[darova]

You can fill circles and change their size

[Juan Castillo]

Yep, but is there a way to plot the data as a contour plot?

[darova]

YOu can draw each circle with patch, but it's a bad idea

[Juan Castillo]

And what about the contour plot? Sorry for being so insistent

[darova]

If you look in help (contour) you will see that contour is a product of surface. You don't have surface, you have only points. Maybe i don't understand you correctly: what do you mean by contour?
