Adding a 'threshold' line to a clustered bar

Hey everyone,

I'm creating an employee scorecard report for a call center environment, and I'm charting the employee's daily performance against their team's daily performance using a 3-D clustered bar. The y-axis is the date, the x-axis is a time metric, e.g. Average Handle Time. What I want to do is to add a threshold line parallel to the y-axis that marks the target goal. For example, the industry standard for AHT is 300 seconds (5 min.), so I'd like a line which crosses the x-axis at the 5 min. mark. How would I accomplish this?

Thanks in advance!

Thanks for the replies! Yeah, I changed it back to a 2-D chart, but I'm encountering a problem. In addition to the link above, I've also been looking at this:

I get as far as Paste Special > Values, but when I try to change the chart type, the line disappears entirely, although the series is still somewhere in the chart. I've used several colors and weights to make sure I'm not just overlooking the data, but there's nothing there. Any ideas what I'm doing wrong?

Yes. The secondary axes appear, but the series disappears.

Right now I'm just using the example provided on that website, just to make sure I can actually make this whole thing work. I'm not seeing how that formula affects the series, though.

The x values are also not text. I thought that might be causing a problem, but they're decimals, formatted as Custom > mm:ss. However, for this example, I'm using 0 and 1.
