2;
determining time-based distribution of the multiple pieces of spatial-temporal data according to time recorded by the multiple pieces of spatial-temporal data;
displaying a distribution curve diagram by using a display device, wherein the distribution curve diagram is used to represent the time-based distribution of the multiple pieces of spatial-temporal data, and the distribution curve diagram comprises a timeline, a curve changing with the timeline, and an irregular region enclosed by the curve;
determining distribution of the multiple pieces of spatial-temporal data in the m regions according to the locations recorded by the multiple pieces of spatial-temporal data; and
displaying, by using the display device, a tree map in the irregular region according to the distribution of the multiple pieces of spatial-temporal data in the m regions, wherein the tree map divides the irregular region into m sub-regions that are in a one-to-one correspondence with the m regions, and an area of each of the m sub-regions is used to indicate an amount of spatial-temporal data distributed in a region corresponding to each sub-region.
