Ken, I should have also noticed that you were trying to set the type with setColumnProperty. That doesn't work since the properties are only for additional user-defined properties, not things like 'type'. But there is no setColumnType() method either. So to use the DataTable (without the DataView) would have to instead add a header row to your arrayData that specifies the types of the columns and pass that to arrayToDataTable().
Using the DataView may be cleaner for you after all. You can read all the documentation on the DataView class at https://developers.google.com/chart/interactive/docs/reference#DataView_setColumns On Sun, Dec 21, 2014 at 7:23 PM, Ken Burkhalter <[email protected]> wrote: > Well, I'm a glutton for punishment so I could not resist going back to the > old code and trying it. > > Using this approach... > > var data = google.visualization.arrayToDataTable(arrayData); > > // Set chart options > data.setColumnProperty (0, 'type', 'number'); > data.setColumnProperty (1, 'type', 'number'); > yada, yada. > > to initialize the column definitions, there was NO success.
