核心图x轴标签不可见 - 边界的影响？(core-plot x-axis label not visible - bounding rects?)

 使用垂直条形图示例作为开始，我创建了一个图表，其y值为0..1，x值为1..n但是没有出现为我的数据源的CPTBarPlotFieldBarLocation单元格提供的x标签索引; 我不使用y轴标签。 
 

 我怀疑我正在削减它们。 是否有一种方法，比如在旧的IB中，绘制各种图形区域的边界矩形？ 
 

 x轴绘图标签是非数字字符串，如示例中所示。 我打破了什么？ 这是我的设置

 如果有明显的线索 - 绘制了界限，我认为我们中的很多人都可以从中受益（我想念那些来自IB大约v3的人）。 

Using the vertical bar chart sample as a start, I created a chart whose y values are 0..1, x values 1..n but the x label index supplied for CPTBarPlotFieldBarLocation cell of my data source doesn't appear; I don't use y-axis labels. 
 

I suspect I'm clipping them. Is there a way, like in the old IB, to draw the various graph region's bounding rect?
 

The x-axis plot labels are a non-numeric string as in the example. What did I break? Here's my setup
 

//
//  InfoBarView.m

#import "InfoBarView.h"

//  Item index to color mapping for legend symbols not item related

static const BOOL kUseHorizontalBars = NO;

static NSArray <__kindof NSString *> const* kTargets = nil;
static NSArray <__kindof NSString *> const* kGetters = nil;

If there were visible clues - drawn bounding rects, I think a lot of us could benefit from them (I miss those from IB circa v3).

最满意答案

 我的一般建议是保留一个“dev”配置文件，该文件适用于大多数开发人员，然后使用不受版本控制的每个开发人员配置文件或使用环境变量来覆盖它。 

Doing this will work:
 

git merge --no-ff --no-commit devEnv-Jake 

 

Follow it up with: 
 

git reset 

 

to clear the files from the staging area.
 

 

I actually created an alias to do this:
