Dashboard charts

How do I include a goal line for a performance metric in a chart? In Excel, I can do a column chart and switch one of the metrics to a line to show the goal, but I can't figure out how to do it in the chart on the dashboard. I don't want to show it as a stacked or with a goal next to each metric. I have 12 performances to illustrate in one chart, so that would be too busy.

Here is an image of what I hope to achieve. Any suggestions?
