I am studying yearly variations in sea level from 1993 to 2017. I import the excel file and assign x and y titles to the columns; x for the year and y for the sea level (in meters). I get an error as follows:
Error using boxplot>straightenX (line 896) 'X' parameter must be a numeric vector or matrix. Error in boxplot (line 274) [xDat,gDat,origRow,xlen,gexplicit,origInd,origNumXCols] = straightenX(x,g);
I would be grateful if someone could help me with this, preferably if you could send me the code. I've tried a couple of different ways but not successful. Thanks
(I have attached excel file titled 'sl.csv')

Use it like this
data = readtable('sl.csv');
boxplot(data.Var2, data.Var1)
