iOSPlot：如何在同一视图中显示多个图表？

Question

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

我从这个链接

https://github.com/honcheng/iOSPlot

图表显示正常下载API。

我想在同一个视图下显示一个图下方的其他图。

我该怎么做？

我想这是打印出来的UIView图表和按我的要求，图表可能超过1

所以，我怎么能显示在同一视图多个图表？

Answer 1

它不工作？

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 

或者这样说：

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 
}
