Hi guys,
I need to plot the Cp values obtained from the experimental results and the CFD computed results in a single plot to compare. The coordinates in the experimental results are (x, y)=(xbyc, neg Cp) where as the coordinates in Computed results are (x, y)=(x, pressure_coefficient).

When both the data files are loaded in Tecplot, only the plot for the firstly loaded file is shown, and the secondly loaded file isn't shown.

Here, I believe the problem is because of the change in the coordinate names, for to overcome that I followed the below steps:
After loading both the files,
s1) Data-->Alter-->Specify Equations
s2) I equated the variables of X-axis for both files, i.e., V1=V10 (for to achieve x=xbyc) and followed the same step for equating the Y coordinates)
s3) Selected the zones of the secondly loaded file
s4) Compute
s5) Selected the two Zones from both Files

After following the above steps, the graph shows a single straight line parallel to Y axis, at 'x=0'.

Software version: Tecplot 360 EX 2014 R1
can Somebody help me please!!

Bharatesh, this tutorial video http://172.16.144.14/blog/2015/05/22/linked-cp-curves/ on Tecplot's web-site shows the creation of linked Cp curves may be helpful for your application.

Sorry that I am unable to answer your question directly.
