Avionics data curve play method and system

Abstract

The invention discloses an avionics data curve play method and system. The method comprises the steps of directly drawing a fitted curve when the total data quantity of the avionics data is less than or equal to a screen pixel quantity; selecting two avionics data with closest transverse axis value horizontal distance to the pixel point from a first dimensional interval of an adjacent pixel point of each pixel point when the total data quantity falls between a one-time screen pixel quantity and two-time screen pixel quantity, and drawing a vertical line with a pixel width and perpendicular to the transverse axis by adopting longitudinal coordinate values of the two avionics data as terminal values, and obtaining a fitted curve formed by combining a plurality of vertical lines; selecting a maximal longitudinal coordinate value and a minimal longitudinal coordinate of the avionics data in the first dimensional interval corresponding to each pixel point when the total data quantity is greater than the two-time screen pixel quantity, drawing a vertical line with a pixel width and perpendicular to the transverse axis by adopting the two values as terminal values, and combining a plurality of vertical lines to form a fitted curve.
本申请公开了一种航电数据的曲线回放方法及系统,当所有航电数据的总数据数量不大于屏幕像素数量时,直接绘制拟合曲线;当总数据数量位于一倍屏幕像素数量和二倍屏幕像素数量之间时,在每个像素点的相邻像素点的第一维度区间选取距离该像素点对应的横轴值水平距离最近的两个航电数据,以这两个航电数据的纵坐标值为端点值,绘制一条宽度为一个像素宽度且垂直于横轴的竖线,得到由多个竖线组合成的拟合曲线;当总数据数量大于二倍屏幕像素数量时,选取每个像素点对应的第一维度区间内航电数据的最大纵坐标值和最小纵坐标值,以这两个值为端点值,绘制一条宽度为一个像素宽度且垂直于所述横轴的竖线,得到由多个竖线组合成的拟合曲线。
