You should be able to use the same methodology you are using with Measure Values and drag additional measures on to this shelf (there is no limit here on the number of Measure Values that can be displayed on the same chart).
Try this - create an additional measure calculated field and drag it to Measure Values - you should see it on the chart.
Another option to consider is dual axis - you can also drag an additional measure to the Rows shelf and then use a Dual Axis chart to display it on the same chart as the Measure Values - this comes in handy when the y-axis values are very different (e.g. displaying sales & percentages on the same chart).
Hope this helps,
It helped. Thank you, Steve!
