Hi, i just started using Matlab for a personal project, I don't have any experience with it.
I'v tried to plot scatter plots with 3 different appropriate data sets and they all get the same error:

This is the same for every data set that I use...
Can i please get some help trying to fix this? Here's line 56HALLLLAO 2019-08-14 at 8.46.22 pm.png
Thank you!

Jackie - is the MATLAB code that you have posted above from the built-in MATLAB scatter function? Or is it something hat you have written? In the command window type
which scatter -all
to see which implementations of this function exist. If more than one exists, then you may want to rename your function to not conflict with the built-in one.
As for the error, at line 55 the boolean allowNonNumeric is defined but allowNumeric is being passed into the getRealData function. If this is your code, then try modifying it to keep the variables consistent.

I'v changed the allowNonNumeric to allowNumeric in scatter.m, it seems to work, thank you!
Just wondering does all MATLAB copies comes with NonNumeric settings, I'm pretty sure i've never fiddledd with it.

"allowNonNumeric" and "allowNumeric" are different variables, you defined first one and forgot last one (I assume this is mistake).
Good reference with ready to try examples is here

Hi, I tiredd the example codeds, they all seem to work... But my data set doesn't. I was thinking maybe it's to do with the size of the data? I have 2 columns with about 4000 cells each..
Thank you!
