我正在用coreplot創建條形圖.Bar圖表正在顯示,但其顛倒..X軸開始在屏幕的頂部,而不是在屏幕的底部..and即使X軸是不可見的..它看起來好像在圖表中的酒吧懸掛:(....我如何改變其位置,使其正確,甚至使X軸可見???上下顛倒x_axis
這裏是我的代碼:
- (void)viewDidLoad {
[super viewDidLoad];
[self generateDataSamples];
double xAxisStart = 0;
double xAxisLength = 14;
double yAxisStart = 0;
// double yAxisLength = [[samples valueForKeyPath:@"@max.Y_VAL"] doubleValue];
double yAxisLength = 190.0;
CPGraphHostingView *hostingView = [[CPGraphHostingView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:hostingView];
CPXYGraph *graph = [[CPXYGraph alloc] initWithFrame:self.view.bounds];
hostingView.hostedGraph = graph;
CPXYPlotSpace *plotSpace = (CPXYPlotSpace *)graph.defaultPlotSpace;
plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromDouble(xAxisStart)
length:CPDecimalFromDouble(xAxisLength+1)];
plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromDouble(yAxisStart)
length:CPDecimalFromDouble(yAxisLength+3)];
CPBarPlot *plot = [[CPBarPlot alloc] initWithFrame:CGRectZero];
plot.plotRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromDouble(0.0)
length:CPDecimalFromDouble(xAxisLength-5)];
plot.barOffset = CPDecimalFromDouble(1.5);
plot.dataSource = self;
[graph addPlot:plot];
[plot release];
[graph release];
[hostingView release];
}

嗨..problem解決了..實際上,我創建了uiview上面,我創建了圖形託管視圖,其中圖形添加..刪除一切都在圖形託管視圖給了我適當的圖形..仍然在尋找掃管笏是與前面的代碼的錯誤.... – Archana
現在我得到類似的問題,添加標籤..M靜態添加標籤通過傳遞數組內循環和設置位置的X和Y軸.. ..傳遞彩色圖像數組和標籤數組..即使在這裏M倒過來標籤和彩色圖像..瓦特問題可能是...下來是代碼: – Archana
