[0023] figure 1 It is a schematic diagram of the effect of selecting data points on the chart through gesture operation in the prior art. Such as figure 1 As shown in , only when a data point on the data line is selected by gesture operation, the corresponding display will be displayed. It should be noted that the actual data points are not shown enlarged, figure 1 In order to illustrate the situation, the selected data points are enlarged. Since a data point is displayed, and the display screen of a general mobile device client is small, it is not easy to determine whether the data point is selected, nor is it easy to see the selected data point clearly.

Abstract

The invention relates to a gesture center drawing method and device on a chart. The method comprises the steps of detecting a contact with a touch-sensitive display, determining central point coordinate values of a center point of the contact, when the central point coordinate values are within the coordinate system of the chart displayed by the touch-sensitive display, determining data point coordinate values of a data point on a data line displayed on the chart which corresponds to the center point, according to the determined center point coordinate values, and drawing a cross line and a circular pattern according to the data point coordinate values. According to the technical scheme, a user is facilitated to select a required data point in the chart of the touch-sensitive display by means of a gesture operation, and the use experience of the user is enhanced.

Description

technical field [0001] The invention relates to the technical field of financial notes, in particular to a method and device for drawing a gesture center on a graph. Background technique [0002] For market trading apps, it is necessary to grasp the changes in market charts in real time.
