Hi, I try to plot a defined area of data in an XLSX file, the area is defined from by the columns C11-C6796 and D11-D6796
So I define the upper left corner by C11 and the lower right corner by D6796. Which I then want to plot, but with
T=readtable('tempDataTrollhFlygpl.xlsx',Range="C11:D6796",ReadVariableNames=false);
plot(T)
xlabel('Year');
ylabel('Temperature');
I get
"Error using plot
Invalid number of input arguments. Specify one or two table subscripts after the table.
Error in uppgift32 (line 2)"
So the error is in the T part of the plot command? I used the MATLAB documentation to define the specific area of data to go in a 2D plot, but why does not that work?
Thanks

What variables in T do you wnat to plot? Since T is a table, you must use one of these syntaxes

Your data is being read in as text. Here's another option that demontrates the table syntax.
T=readtable('tempDataTrollhFlygpl.xlsx',Range="C11:D6796",ReadVariableNames=false,TextType="string");
T = convertvars(T,"Var2","double")
plot(T,"Var1","Var2")
xlabel('Year');
ylabel('Temperature');
