The disclosed embodiments include systems and methods to evaluate formation resistivity. In one embodiment, a method to evaluate formation resistivity proximate a wellbore is provided. The methods includes receiving data indicative of resistivity measurements of a formation proximate a wellbore at different distances within a range of distances from the wellbore. The method also includes analyzing the data to determine approximate formation resistivity of the formation at different distances from the wellbore. The method further includes generating at least one curve, each indicative of an approximate formation resistivity of the formation at the different distances from the wellbore, overlaying the at least one curve on a graph indicative of the formation resistivity of the formation within the range of distances from the wellbore, and providing the at least one curve overlaid on the graph for display on a device.
