1. An apparatus for estimating bio-information, the apparatus comprising:
a photoplethysmogram (PPG) sensor or a communication interface configured to acquire a bio-signal of a user;
a processor configured to apply weights to time values of a plurality of characteristic points of the bio-signal, respectively, determine internally dividing points of the plurality of characteristic points based on a sum of the weights, and extract feature values from the bio-signal based on the internally dividing points to perform bio-information estimation; and
a display configured to display a graph of the bio-information which has been measured over time, and display a mark configured to move along the graph according to a user input to allow the user to select a specific data point from the graph.
