如何使用Core Plot在图表中绘制水平条？ [英] How do I draw horizontal bars in a chart using Core Plot?

问题描述

我是Core Plot框架的初学者。现在，我可以在屏幕上绘制条形图。

I'm beginner with the Core Plot framework. Right now, I am able to render bar charts on the screen.

但是，我需要绘制水平条形图，其条形从Y轴延伸，就像这样：

However, I need to draw a horizontal bar chart that has the bars extending from the Y axis, like so:

 ^
y|
 |****
 |*******
 |**********
 |******
 |---------------> x

我如何在Core Plot中实现这样的水平条形图？

How would I implement such a horizontal bar chart in Core Plot?

推荐答案

您说您正在使用core-plot，该框架中包含示例代码，其中已实现barChart。您可以看一下。

you said you are using core-plot, there are sample codes with the framework, in which barChart has been implemented. You can have a look at it.

编辑：

对不起，我看到您现在进行了更新，我得到了您需要单杠。使用以下代码。

Sorry I saw you update now, and I got you need horizontal bars. Use following code.

CPBarPlot * barPlot = [CPBarPlot ...];
[barPlot setBarsAreHorizontal:YES];
