GitHub - Maling1255/MGChartLineView: 分段绘制折线指示图

来自 : github 发布时间：2021-03-24

// 竖直指示线 UIView *markLine = [[UIView alloc] initWithFrame:CGRectMake(center.x - 0.5, center.y - 0.5, (1-center.y / self.yAxis_L) * self.yAxis_L + self.startPoint.y)]; markLine.tag = i + BASE_TAG_CIRCLEVIEW*2 ; [self addSubview:markLine];

第三部分 绘制折线

// 添加覆盖- (void)setupCoverViews for (int i = 0; i pointArray.count; i ++) UIView *coverView = [[UIView alloc] init]; coverView.tag = BASE_TAG_COVERVIEW + i; CGPoint point = [pointArray[i] CGPointValue]; coverView.frame = CGRectMake(point.x - self.xScaleMarkLEN / 2, self.startPoint.y, self.xScaleMarkLEN, self.yAxis_L);
这里主要讲解 MGChartLineView 类的内容,主要分为3个部分第一部分 绘制折线/** * 绘制折线路径 */ - (void)drawChartLine { UIBezierPath *pointAxisPath = ...分段绘制折线指示图. Contribute to Maling1255/MGChartLineView development by creating an account on GitHub.GitHub
