Table variables containing the x-coordinates, specified as one or more table variable indices.

Use any of the following indexing schemes to specify the desired variable or variables.

Variable names:

A string, character vector, or cell array.

A pattern object.

"A" or 'A' — A variable called A

["A","B"] or {'A','B'} — Two variables called A and B

"Var"+digitsPattern(1) — Variables named "Var" followed by a single digit

Variable index:

An index number that refers to the location of a variable in the table.

A vector of numbers.

A logical vector. Typically, this vector is the same length as the number of variables, but you can omit trailing 0 or false values.

3 — The third variable from the table

[2 3] — The second and third variables from the table

[false false true] — The third variable

Variable type:

A vartype subscript that selects variables of a specified type.

vartype("categorical") — All the variables containing categorical values

The table variables you specify can contain numeric, categorical, datetime, or duration values.

To plot one data set, specify one variable for xvar, and one variable for yvar. For example, read Patients.xls into the table tbl. Plot the Diastolic variable versus the Weight variable.

To plot multiple data sets together, specify multiple variables for xvar, yvar, or both. If you specify multiple variables for both arguments, the number of variables must be the same.

For example, plot the Systolic and Diastolic variables against the Weight variable.

You can use different indexing schemes for xvar and yvar. For example, specify xvar as a variable name and yvar as an index number.
