Where is the chart menu?

[kenab1]

This is really annoying me because it's beyond basic, but I can't seem to get the chart menu to pop up. I created a chart and now I want to do a linear regression but the chart menu isn't popping up. I click on the chart and nothing happens. Can anyone tell me what I'm doing wrong here? Thanks

Did you group the chart with another graphic, e.g., a textbox?
