A method for processing data, comprising: transmitting , by a terminal device, a data request to a server, the data request including at least data associated with a display area of a window; receiving , by the terminal device, trace data from the server according to the data request, the trace data including dynamic motion data of a target object within the display area; and processing , by the terminal device, the received trace data to render a trace image in the display area, wherein processing the received trace data to render the trace image in the display area includes: processing the received trace data to render the trace image according to at least one of a first rule of selecting a method of rendering images; wherein the method of rendering images includes a dot pattern rendering mode and a line pattern rendering mode, and processing the received trace data to render the trace image in the display area further includes: determining a rendering density of the trace image, based on at least one of a sampling frequency of the received trace data and a scaling value of the trace image, when the rendering density of the trace image is greater than a first threshold, selecting the dot pattern rendering mode to render the received trace data in the display area, and when the rendering density of the trace image is smaller than the first threshold, selecting the line pattern rendering mode to render the received trace data in the display area. transmitting , by a terminal device, a data request to a server, the data request including at least data associated with a display area of a window; receiving , by the terminal device, trace data from the server according to the data request, the trace data including dynamic motion data of a target object within the display area; and processing , by the terminal device, the received trace data to render a trace image in the display area, wherein processing the received trace data to render the trace image in the display area includes: processing the received trace data to render the trace image according to at least one of a first rule of selecting a method of rendering images; wherein the method of rendering images includes a dot pattern rendering mode and a line pattern rendering mode, and processing the received trace data to render the trace image in the display area further includes: determining a rendering density of the trace image, based on at least one of a sampling frequency of the received trace data and a scaling value of the trace image, when the rendering density of the trace image is greater than a first threshold, selecting the dot pattern rendering mode to render the received trace data in the display area, and when the rendering density of the trace image is smaller than the first threshold, selecting the line pattern rendering mode to render the received trace data in the display area. determining a rendering density of the trace image, based on at least one of a sampling frequency of the received trace data and a scaling value of the trace image, when the rendering density of the trace image is greater than a first threshold, selecting the dot pattern rendering mode to render the received trace data in the display area, and when the rendering density of the trace image is smaller than the first threshold, selecting the line pattern rendering mode to render the received trace data in the display area. <EOS>
