To analyze the bottom flow inside a pipe in Ansys fluent, we wanted to model it in 2D and perform the analysis with axisymmetry. 
If you suddenly check the check case in the Run calculation, the ansys boundary (boundary condition) of the center line (x-axis)
It pops up like this and I already have the center line set as the axis in the boundary conditions. How can I solve this problem?
And I want to plot residual. How can I do?

It's a warning, so if the centre is defined correctly you can ignore it. 

Residuals will automatically start plotting, otherwise look in the Monitors menu (left tool tree).
