I have created a graph with two measures to show the number of orders and the orders value at a given point in time in the year. I would like to insert a moveable vertical marks like that will display data value from both graph lines. Please click the Zillow hyperlink below to better understand my objective. Once the page is open, scroll to down to locate the Zestimate graph. Roll your mouse over the graph to display the faint gray vertical marks line.
If you have a continuous axis, you can use drop lines. However, you will have to click on the data point for the line(s) to show. As far as I know, you cannot show them just by hovering over the data points.
