Inclusive \jpsi production cross section at midrapidity ($|y|<0.9$) in \pp collisions at \thirteen compared with the ALICE forward-rapidity measurement at \thirteen~ (left panel) and the scaled ALICE midrapidity measurements at \five~ and \seven~ (right panel). The error bars represent statistical uncertainties while the boxes around the data points represent the total systematic uncertainty, excluding the global uncertainty from the luminosity and branching ratio. The lower panels show the ratio between the measurements at different rapidity and energies, and the power law fit, discussed in the text, to the \jpsi production cross section (red dashed line) at midrapidity at \thirteen. The boxes in the lower panels include the systematic uncertainty of the data points and the uncertainty of the integral of the fit function in the given \pt interval added in quadrature.
