Hi,

Just came across a problem with the Annotated Time Line Visualisation.
Essentially if you submit

hideDataColumns(10)

it will hide the 11th column in the array (index 10).

If you run the command

hideDataColumns("10")

It will hide the first and second column (indexes 0 and 1)

I do not feel this is made entirely clear in the API, and I would
recommend anyone who is dynamically hiding and displaying columns that
they use something like the parseInt method on the value of the column
so that they can hide the correct columns.
