You will see centerline created under User Locations and Plots.
Next, we will create a chart using this Location data. 
Insert > Chart 
Enter "Axial Pressure" as Name. You will see Details of Axial Pressure appear on the lower left panel. Under General, give the chart Title as "Pressure Variation along Pipe Axis".

Now click on Data Series tap to specify the location of the chart data. Create a new data series Image Added.  Change the name from Series 1 to FLUENT. Under Data Source, specify Centerline as Location.

We would also like to compare our simulation result with experimental data. Experimental data is can be downloaded here. Download it to the directory that you like. Now, click a new data series Image Added. Name it Experiment. Under Data Source, select File and browse to the downloaded experimental data.

Now we will specify the X Axis parameter. Click on X Axis tab. Next to Variable, choose X.

Now we will specify the Y Axis parameter. Click on Y Axis tab. Next to Variable, choose Pressure.

Now we will specify how we want to the chart to display. The default setting is to display the data series in lines. Since we only have 3 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. You will see Axial Pressure created under Report in the Outline tab.  In the Graphics window, you will see the chart.

Does the simulation result compares well with the experimental data? 

Centerline Temperature Plot

Now let's look at the temperature variation along the centerline. 

Insert > Chart 
Enter "Centerline Temperature" as Name. You will see Details of Centerline Temperature appear on the lower left panel. Under General, give the chart Title as "Temperature Variation along Pipe Axis".

Now click on Data Series tap to specify the location of the chart data. Create a new data series Image Added.  Change the name from Series 1 to FLUENT. Under Data Source, specify Centerline as Location.

We would also like to compare our simulation result with experimental data. Experimental data is can be downloaded Experimental Centerline Temperature.csvhere. Download it to the directory that you like. Now, click a new data series Image Added. Name it Experiment. Under Data Source, select File and browse to the downloaded experimental data. Image Added

Now we will specify the X Axis parameter. Click on X Axis tab. Next to Variable, choose X.
