Hi All,

I am trying to set the line width on a Google chart as follows:

BarChart::create(array(
    "dataSource"=>$combined,
    "columns"=>array(
        "yearGroup" => array("prefix" => "Year "),
        "school"=>array("label"=>"Your School","type"=>"number"),
    ),
    "options"=>array(
        "legend"=>"none",
        "lineWidth"=>1,
        "hAxis"=>array("minValue"=>0, "maxValue"=>100),
        "colors"=>array("#acda84")
    )
));

Everything works and the chart displays, but the lineWidth setting does not work. As far as I can see it matches the Google Charts documentation (https://developers.google.com/chart/interactive/docs/lines).

Can anybody suggest what the issue is please - thanks in advance.

Annoyingly - 5 seconds after posting I realised my mistake - "lineWidth" is the option for line charts, for bar charts I have to do the following "bar"=>array("groupWidth"=>5), hopefully this will help anybody else having the same issue.
