黑色方形边框出现在核心情节饼图中

Question

CPTXYGraph *graph   = [[CPTXYGraph alloc]initWithFrame:self.hostingView.frame];
graph.borderColor   = [CPTColor whiteColor].cgColor;
graph.paddingTop    = 0.0f;
graph.paddingRight  = 0.0f;
graph.paddingLeft   = 0.0f;
graph.paddingBottom = 0.0f;
self.hostingView.hostedGraph = graph;
graph.axisSet = nil;


//Apply for theme to graph
self.graphTheme = [CPTTheme themeNamed:kCPTPlainWhiteTheme];
[graph applyTheme:self.graphTheme];
[graph release];

CPTPieChart *pieChart = [[CPTPieChart alloc]init];
pieChart.identifier = @"OverView";
pieChart.dataSource = self;
pieChart.sliceDirection = CPTPieDirectionClockwise;
pieChart.pieRadius = ((self.hostingView.frame.size.height  / 2) - 5);
pieChart.startAngle = M_PI;
CPTGraph *tempGraph = self.hostingView.hostedGraph;
    [tempGraph addPlot:pieChart];
[pieChart release];

对于这个代码我得到黑色边框，我认为这是由于graph axisSet但我不知道如何删除。

Answer 1

如果您正在谈论的是整个图表周围出现的边框，我会说在语句[graph applyTheme:self.graphTheme];之后使用此代码：

graph.plotAreaFrame.borderLineStyle = nil;

这将完全从图形区域中删除边框。
