Hi everyone,

In the following JSON:

            var data = new google.visualization.DataTable(
                {
                cols: [{id: 'Option1', label: 'Manufacturer', type:
'string'},
                       {id: 'Option2', label: 'Region', type:
'string'},
                       {id: 'Option3', label: 'Option3', type:
'number'},
                       {id: 'Option4', label: 'Option4', type:
'number'},
                       {id: 'Option5', label: 'Option5', type:
'number'},
                       {id: 'Option6', label: 'Option6', type:
'number'},
                       {id: 'Option7', label: 'Option7', type:
'number'},
                       {id: 'Option8', label: 'Option8', type:
'number'}],


                rows: [{c:[{v: 'Ford'}, {v: 'South East'}, {v: 2}, {v:
3}, {v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'Ford'}, {v: 'South East'}, {v: 2},
{v: 3}, {v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'Ford'}, {v: 'South East'}, {v: 2},
{v: 3}, {v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'BMW'}, {v: 'South East'}, {v: 2}, {v:
3}, {v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'BMW'}, {v: 'North'}, {v: 2}, {v: 3},
{v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'BMW'}, {v: 'North'}, {v: 2}, {v: 3},
{v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'Citroen'}, {v: 'North'}, {v: 2}, {v:
3}, {v: 4}, {v: 5}, {v: 6}, {v: 7}]},
                        {c:[{v: 'Citroen'}, {v: 'South East'}, {v: 2},
{v: 3}, {v: 4}, {v: 5}, {v: 6}, {v: 7}]}
                        ]
                },
                0.6
            )


my graph 'will' display the manufacturers as rows with 7 bars of data
against each.

I want to be able to filter the data using a dependent control in
order to see just the rows in each region (column 1).

At the current time this graph does not draw because the region column
is not a integer and so it cannot be displayed.

Therefore I want to 'hide' the region column so that it is not
displayed as a bar, but is available for use with the dependent
control.

Can anyone help with this as I cannot find any way to do it? I don't
think that the hideColumns method will work because that removes the
column from the data object and there3fore the dependent control
cannot see it.
