Display settings for a Funnel Chart so the whole chart can be seen in a Dashboard Dashlet

I am using a funnel chart on my sales dashboard and I would like to scale down (fit to width) the chart so when the dashlet (chart) sits in is in a single row on my dashboard the whole chart can be seen. I can stretch the dashlet so it takes space in two rows and I am able to see the whole chart. To save space though, I would like to see the whole chart when the dashlet sits in a single row. Does anyone know if there are display settings (fit to width or something else) that I can set so the whole chart displays no matter how big or small I make the dashlet?
