how to use surf function instead of gscatter?

Hi!

I am trying to find alternatives of using gscatter function as I dont want to buy the machine learning tool box that can make it possible to use the gscatter function. Therefore, I searched a little and found that I could use the surf function.

How can I use the surf function on the table attached if I want to group my data ( x= samlet_vannaktivitet, y= osmotisk_trykk) meaning have my z value equal to zone_number?

You don't have enough data to make a surface plot.

If you really want a scatter plot, why not just use scatter and plot each group separately?

If you want to create a surface and you have 2D coordinates, what defines the z-values?

BTW, your data is only 3 rows and we don't know what you're plans are with the data.

@Adam Danz Hi

The reason why I cant use scatter og gscatter is because I just have matlab 2018b , I have not upgraded to matlab 2019 or later versions and I dont have the add on toolbox of machine learning and statistics that can make me able to plot gscatter..

The scatter function has been around well before 2018 and does not require a toobox.

@Adam Danz what is then the difference between scatter and gscatter function..?

[Adam Danz]

scatter - creates a scatter plot

gscatter - creates a scatter plot of grouped data
