I have a table that was imported into the work space, and I am unsure on why it is unable to be located. The table in the workspace is named "LabData3". Two of the colunms in this table are named "Qgpm" and "hpft".
Tab = readtable('LabData3');
scatter(Tab,'Qgpm','hpft');
Error using readtable (line 498)
Unable to find or open 'LabData3'. Check the path and filename or file permissions.
Error in Lab3 (line 1)
Tab = readtable('LabData3');

Replace your line
Tab = readtable('LabData3');
with
Tab = LabData3;

Only in (I think) the most recent version of MATLAB will
scatter(Tab,'Qgpm','hpft');
work. https://www.mathworks.com/help/matlab/ref/scatter.html
In earlier versions, use scatter(Tab.Qgpm,Tab.hpft);
