如何删除核心绘图图周围的边框

您应该能够消除图的plotarea上的borderlinestyle以删除边框:

graph.plotAreaFrame.borderLineStyle = nil;    // don't draw a border

您也可以创建自己的主题,使用框架中的主题作为示例,而不必在其中设置borderlinestyle。

所有的答案对我都不起作用。这样做的目的是:

graph.paddingLeft = 0;
graph.paddingRight = 0;
graph.paddingTop = 0;
graph.paddingBottom = 0;
graph.plotAreaFrame.borderWidth = 0;
graph.plotAreaFrame.cornerRadius = 0;

好吧,我知道怎么做了-真的很简单!

CPLineStyle *borderLineStyle = [CPLineStyle lineStyle];
borderLineStyle.lineColor = [CPColor whiteColor];
borderLineStyle.lineWidth = 1.0;

graph.plotArea.borderLineStyle = borderLineStyle;

其中graph是你的图形对象——我之所以有一个边界,首先是因为我使用了cpplainwhitetheme。

希望这能帮助别人-有更好的方法吗?

可以将任何线条样式设置为 nil . 这将导致线条根本无法绘制。

在Coreplot 1.0中, CPTGraph 有点变化。删除图形边框线的代码,假定 graph 属于类型 GPTGraph 或 CTP图 是

graph.plotAreaFrame.borderLineStyle = nil;

应用后borderlinestyle=nil的正确方式:

CPTGraph *graph = [[CPTXYGraph alloc] initWithFrame:hostView.bounds];

// Set padding for plot area
[graph applyTheme:[CPTTheme themeNamed:kCPTPlainWhiteTheme]];
graph.plotAreaFrame.borderLineStyle = nil;

如果像我一样,您不仅要删除边界线,而且要绘制占用整个宿主视图的绘图,则 answer 从 Thomas Johannesmeyer 让我走上正轨。

我是这样做的:

CPTGraphHostingView* hostingView = [[CPTGraphHostingView alloc] initWithFrame: frame];
CGRect bounds = hostingView.bounds;

CPTGraph *graph = [[CPTXYGraph alloc] initWithFrame:bounds];
hostingView.hostedGraph     = graph;

graph.paddingTop    = CPTFloat(0.0);
graph.paddingRight  = CPTFloat(0.0);
graph.paddingBottom = CPTFloat(0.0);
graph.paddingLeft   = CPTFloat(0.0);

graph.plotAreaFrame.paddingTop    = CPTFloat(0.0);
graph.plotAreaFrame.paddingRight  = CPTFloat(0.0);
graph.plotAreaFrame.paddingBottom = CPTFloat(0.0);
graph.plotAreaFrame.paddingLeft   = CPTFloat(0.0);
graph.plotAreaFrame.masksToBorder = NO;

CPTXYAxisSet *axisSet = (CPTXYAxisSet *)graph.axisSet;
CPTXYAxis *x          = axisSet.xAxis;
x.labelingPolicy      = CPTAxisLabelingPolicyNone;
x.title = nil;
CPTXYAxis *y          = axisSet.yAxis;
y.labelingPolicy      = CPTAxisLabelingPolicyNone;
y.title = nil;
