priceandvol

Price and Volume chart

priceandvol is updated to accept data input as a matrix, timetable, or table.

The syntax for priceandvol has changed. Previously, when using table input, the first column of dates could be a datetime array, date character vectors, or serial date numbers, and you were required to have specific number of columns.

When using table input, the new syntax for priceandvol supports:

• No need for time information. If you want to pass in date information, use timetable input.

• No requirement of specific number of columns. However, you must provide valid column names. linebreak must contain columns named 'open', 'high', 'low', 'close', and 'volume' (case insensitive).
