ios：Coreplot多個數據集具有相同的數據源並重疊？

我想在同一散點圖上顯示兩行。我已成功將兩者都放在一張圖表上。一個是綠色的，另一個是紅色的。ios：Coreplot多個數據集具有相同的數據源並重疊？

截至目前，它們似乎是從相同的數據源拉，因此它們重疊。

如果有人可以請告訴我如何訪問graphdata中的其他數據，我將不勝感激！

enter image description here

NSArray* data = [[NSArray alloc] initWithArray:_graphData]; 

    NSDictionary*ds1 = [data objectAtIndex:0]; 
    NSDictionary*ds2 = [data objectAtIndex:1]; 

    CPTScatterPlot *plot = [[[CPTScatterPlot alloc] init] autorelease]; 
    plot.identifier = [ds1 objectForKey:@"PLOT_IDENTIFIER"]; 

    CPTMutableLineStyle *tyle = [[plot.dataLineStyle mutableCopy] autorelease]; 
    tyle.lineWidth = 19.f; 
    tyle.lineColor = [CPTColor redColor]; 
    tyle.dashPattern = [NSArray arrayWithObjects:[NSNumber numberWithFloat:8.0f], nil]; 
    plot.dataLineStyle = tyle; 

    plot.dataSource = self; 
    NSLog(@"%@",plot.dataSource); 

    [self.graph addPlot:plot]; 

    CPTScatterPlot *plot2 = [[[CPTScatterPlot alloc] init] autorelease]; 
    plot2.identifier = [ds2 objectForKey:@"PLOT_IDENTIFIER"]; 
    CPTMutableLineStyle *tyle2 = [[plot2.dataLineStyle mutableCopy] autorelease]; 
    tyle2.lineWidth = 12.f; 
    tyle2.lineColor = [CPTColor greenColor]; 
    tyle2.dashPattern = [NSArray arrayWithObjects:[NSNumber numberWithFloat:8.0f], nil]; 
    plot2.dataLineStyle = tyle2; 

    plot2.dataSource = self; 

    NSLog(@"%@", plot2.dataSource); 

    [self.graph addPlot:plot2];

這裏是數據：

添加到'data1'和'data2'的對象看起來像包含相同的'CGPoint'值。繪製點的任何原因不會重疊？ – bobnoble

數據2確實包含與數據1不同的點。但是，它不是一組完整的數據點，所以我複製並粘貼了第一個表中的缺失數據，因爲我認爲它可能有效？任何其他想法？ – pj409

檢查您的數據源。我懷疑數據源方法不能正確區分圖。確保每個繪圖都有唯一的identifier，並在數據源中使用它來確定哪個繪圖正在請求數據。
