iOSPlot：如何在同一视图上显示多个图表？

Question

我正在开发一个需要图表的 iPhone 应用程序。因此我使用名为 iOSPlot 的 API 来绘制折线图。

我已经从此链接下载了 API

https://github.com/hon Cheng/iOSPlot

图表显示正常。

我想在同一视图中将一个图表显示在另一个图表的下方。

我怎样才能做到这一点？

我想它正在 UIView 上打印出图表，并且根据我的要求，图表可能超过 1 个。

那么如何在同一视图上显示多个图表呢？

Answer 1

它不起作用？

PCHalfPieChart *pieChart1 = [[PCHalfPieChart alloc] initWithFrame:CGRectMake(10, 10, 50, 50)];
[self.view addSubview:pieChart1];
// adding dataset1 to pieChart1

PCHalfPieChart *pieChart2 = [[PCHalfPieChart alloc] initWithFrame:CGRectMake(70, 10, 50, 50)];
[self.view addSubview:pieChart2];
// adding dataset2 to pieChart2

或者这样：

PCLineChartView * lineChart;

// you should find a way to define your x, y, width and height correctly.
// I have not enough information about your project to find a solution
// I admit that there is 4 var called x, y, width and height

for (int i=0; i < numberOfChart; i++) {
    lineChart = [[PCLineChartView alloc] initWithFrame:CGRectMake(x, y, width, height)];
    // Add some data
    // it can be based on the index to define which data goes to which chart
    // ...

    [self.view addSubview: lineChart];
    [lineChart release];

    // Changing values of x, y, width and height
    // should come here
}
