Again in this case, the x-axis is the x-position along the pipe and the y-axis denotes temperature.  
As previously shown, we will specify how the chart should be displayed. The default setting is to display the data series in lines. Since we only have a few experimental points, we want them to be displayed in data points. Click on Line Display. Then click on experimental tab. Next to Line Style, change Automatic to None. Next to Symbols, change None to Diamond. Change the color to red. Click Apply.
This is what you should see in the Graphics window.

Image AddedThe experimental data are a fairly good match for what the simulation has predicted. The wall temperature in the experiment seems to be consistently higher than the simulation in the heated section. We will later check if refining the mesh improves this agreement.

Pressure Plot

Now let's us look at the pressure variation at the centerline. We can use the center-line we created earlier.
