Make x axis and bars wider on barcharts

Iโ€™m having trouble producing readable bar graphs when the number of bars is above 25 or so. I canโ€™t figure out how to

  1. Increase the overall width of the x axis. I want to get up to basically the size of a full sheet of printer paper
  2. Increase bar width correspondingly. In particular, Iโ€™d love to do this for grouped bar charts

@tmoodyjr In layout set width=1000 or greater.
