multiple plots on one graph in real time

I realize that this has probably come up before on here but I looked and tried examples that seemed similiar and haven't been able to get them to work.

I have multiple thermocouple measurements coming in that I want to plot versus time all on the same graph in real time.  Right now I've only managed to do it with one thermocouple input using the express xy graph and not clearing data with each iteration.  I attached an image of the VI that does a basic one input graph properly.  I would like to have as many as 8 inputs (each would have their own TIn subvi) plotted in seperate line on the graph though.  All attempts I've made so far to plot more than one input connects them together at each sample time with a vertical line so I end up getting a graph that looks like a saw wave.

Any help would be very appreciated...  I'm using labview 7.1 for this.

actually I found the real-time chart.vi that looks like it does almost exactly what I want so I can modify that.
