How to get multiple lines on one graph

I have a data set that consists of pressure readings taken over time for two
rooms. The readings range from -2.5 to +2.5. I want to develop a chart that
has each rooms reading represented by a different line. The y axis would be
pressure and the x axis would be time. I know, sounds simple. However, the
times are not consistent across the data sets...the pressure readings were
taken based on a change of value rather than a designated time interval.

If anyone knows how I can do this I would greatly appreciate the assistance.
I need to do this for approximately 50 different room combinations...so the
easier the better

Make an XY chart from the Room1 data
Select all the Room2 data and Copy
Click the chart; used Edit | Paste Special:
specify New Series with Category data in First column
best wishes

Thank you! It was actually even simpler than that...I just had to copy the
data columns and then past them into the chart. I appreciate your
assistance!
