title: highcharts bar chart: columns width is very thin
body: <p>Columns are very thin in my <a href="http://www.highcharts.com/" rel="nofollow noreferrer">highcharts</a> bar chart. It's not calculating the width automatically. It's not taking the maximum portion of the grid for that related series.
