blocks|key|3117832|text|推动核心绘图项目的众多因素之一是在iPhone上缺乏良好的绘图框架。Core+Plot还涵盖了许多其他用例，包括桌面系统，但它的设计从一开始就包含了iPhone支持。它已经非常接近于可用，目前已经在几个iPhone和OS应用程序中使用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3117833|编辑2/10|offset|length|style|BOLD|3117834|自从我第一次发布摘要以来，Core+Plot已经走过了很长一段路。框架现在有条形图(我相信包括水平条形图)，轴标签(包括不规则的旋转)，以及图形的填充和背景。我不确定堆叠条形图，但将其添加到实现条形图的CPBarPlot类中并不难。至于注解，如果没有您需要的确切功能，您可以子类化CPAnotation类来添加注解。|CODE|3117835|项目on+github。|3117836|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/core-plot^0|0|0|6|0|2T|9|3W|B|0|2|9|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@$D|W|E|X|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|Y|8|@$D|Z|E|10|F|J]|$D|11|E|12|F|J]]|9|@]|A|$]]|$1|K|3|L|5|6|7|13|8|@]|9|@$D|14|E|15|1|16]]|A|$]]|$1|M|3|-4|5|6|7|17|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|T]]]]

One of the many factors that motivated the Core Plot project was the lack of good plotting frameworks on the iPhone. Core Plot also encompases many other use cases including desktop systems, but its design has included iPhone support from the beginning. It's getting pretty close to useable and is currently in use in several shipping iPhone and OS X applications.

Edit 2/10

Core Plot has come a long way since I first posted the summary. The framework now has bar charts (including horizontal bar charts, I believe), axis labels (including aribrarty rotations), and fills and backgrounds for graphs. I'm not sure about stacked bar charts, but it wouldn't be hard to add to the <code>CPBarPlot</code> class that implements bar charts. As for annotations, there is a <code>CPAnotation</code> class which you could subclass to add your annotations, if there isn't the exact functionality you need.

blocks|key|3330684|text|一年或两年前，我进行了自己的搜索，最终制作了自己的线条图形类，因为我找不到任何可以完全按照我需要的方式工作的东西。不过，值得关注的两个大问题是SM2DGraphView和GraphX。我还没有在iPhone项目中尝试过，但我知道SM2DGraphView是开源的，所以如果需要，您可以对其进行修改。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3330685|我还考虑过使用WebView来使用JavaScript图形库，但这只是一个想法。|3330686|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.snowmintcs.com/frameworks/sm2dgraphview/index.html|1|http://blog.oofn.net/projects/graphx/^0|1Z|D|0|2D|6|1|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]|$A|T|B|U|1|V]]|C|$]]|$1|D|3|E|5|6|7|W|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

I went through my own search a year or two ago, and ended up making my own line graphing classes because I couldn't find anything that worked exactly the way I needed it to. The two big ones to look at though, are <a href="http://developer.snowmintcs.com/frameworks/sm2dgraphview/index.html" rel="nofollow noreferrer">SM2DGraphView</a> and <a href="http://blog.oofn.net/projects/graphx/" rel="nofollow noreferrer">GraphX</a>. I haven't tried either in an iPhone project, but I know SM2DGraphView is open source so you could modify it if needed.

I've also considered using a WebView to use a JavaScript graphing library, but that's just a thought.

I have my own library called <a href="http://powerplot.nua-schroers.de" rel="nofollow">PowerPlot</a> which is available under a dual-license model.

You can just follow the above link to install the demo app which shows off several sample charts. You can also download the GPL-version of the library and check out if it fits your needs. With the exception of horizontal bar charts it has the features requested - specifically, bar charts, stacked bar charts, various axis label positions and orientations.

blocks|key|3330747|text|作为CorePlot的商业替代品，我建议尝试一下ShinobiControls，他们有一些非常漂亮的图表。它们也有非常好的性能，以60fps的100,000%2B点渲染图表，并支持多点触控。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3330748|作为一名完全公开的__，我在ShinobiControls的母公司Scott+Logic工作。|style|BOLD|3330749|entityMap|0|LINK|mutability|MUTABLE|url|http://www.shinobicontrols.com/^0|O|F|0|0|4|5|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@$A|U|B|V|F|G]]|9|@]|C|$]]|$1|H|3|-4|5|6|7|W|8|@]|9|@]|C|$]]]|I|$J|$5|K|L|M|C|$N|O]]]]

As a commercial alternative to CorePlot, I'd recommend giving <a href="http://www.shinobicontrols.com/" rel="nofollow">ShinobiControls</a> a go, they have some pretty good looking charts. They also have very good performance, rendering charts with 100,000+ points at 60fps and multi-touch support.

You are free to use it in whatever you want, if you do, let me know! I'll be slowly adding more features to it, if you want something specific ask me through github.

I have a need to render and display charts (bar charts for now, but more types may be needed later) in an iPhone app I'm working on. I've done some looking around and it doesn't look like there are any really good, mature charting libraries for iPhone yet. I've also looked for something written for Cocoa on the Mac that can be adapted, but haven't found anything great yet.

Anybody dealt with this before? Any recommendations? 

I did find <a href="https://github.com/core-plot/core-plot" rel="noreferrer">Core Plot</a>, but it seems to be in the early stages of development.

Edit to add some details of requirements (as they currently stand ;) )

<ul>
<li>Bar Charts</li>
<li>Horizontal bar charts</li>
<li>Double stacked bar charts</li>
<li>Axis labels (including rotated 90 degrees on the y axis)</li>
<li>Labels above each bar on the chart</li>
<li>Shaded or custom backgrounds</li>
</ul>

Is there a good charting library for iPhone?

我需要在我正在开发的iPhone应用程序中呈现和显示图表(目前是条形图，但稍后可能需要更多类型)。我已经做了一些环顾，看起来还没有任何真正好的，成熟的iPhone图表库。我也在寻找在Mac上为Cocoa编写的可以改编的东西，但还没有找到任何很好的东西。以前有人处理过这个问题吗？有什么建议吗？我确实发现了，但它似乎还处于...
