I recives this error:

Subscripting a table using linear indexing (one subscript) or multidimensional indexing (three or more

subscripts) is not supported. Use a row subscript and a variable subscript.

in this command:

             hold on
             plot(Tmean_split{(var_Tmean_split(i))}, 'dg');
             hold off
             

I want to plot mean value on the existing boxplot.

Tmean_split is a table and var_Tmean_split is array string of the table columns.

I don't know what var_Tmean_split is. Is it a cell array of strings that you got from a column of the table called Tmean_split? If so, how can you plot strings? You can only plot numbers.

When you say

Tmean_split{(var_Tmean_split(i))}

the expression inside the {} must be a number saying what column you want to use. Evidently you're not giving it a single number but a cell array, a vector, or a column from a table (I'm not sure), but it's definitely not a single column number.

Can you attach your table in a .mat file with the paper clip icon and say what column you want to plot?

plot(Tmean_split{:, var_Tmean_split(i)}, 'dg');

or

plot(Tmean_split.(var_Tmean_split(i)), 'dg');

I recieved error using

plot(Tmean_split.(var_Tmean_split(i)), 'dg');

Error:

Table variable names must be strings or character vectors.

If your var_Tmean_split really is an array string like you said, then your i is not scalar.

But I suspect that your var_Tmean_split is a cell array of character vectors rather than a string array. If so then in the above, where I have var_Tmean_split(i) replace that with var_Tmean_split{i}
