HomeBackend DevelopmentPHP Tutorial服务器端的Chart解决方案

最近需要在服务器上直接生成数据图表的PNG图片,我知道客户端的解决方案很多,比如:HighChart、amCharts、JS Charts、gRaphael、Aweasome Chart JS、D3等等 可以列出几百种,都是需要javascript运行环境,但我的需求是需要直接生成PNG图片,然后通过邮件啊什么的发送出去。也就是一定要在服务器端绘制好数据图表,生成png图片。

目前服务器端的绘图,PHP语言的有几个都不是免费的:jpGraph、pChart,包括生成html的phpCHART也是需要付费的。而Google Chart API的php封装其实是直接请求google服务器,然后返回数据,对于速度上有影响。其他的一些php免费的如:libchart、GraPHPite、ez Components的Graph库,效果都不好,绘图不够平滑,功能也比较少。

基本上PHP的那些解决方案都不是非常好。
其他语言,我知道python有个matplot库,但是我不懂python语法,也不清楚怎么样。
还有R语言是可以绘图,但是对R一知半解,不知道绘图效果怎样。
专业级的绘图如:metapost、asymptote都需要一个非常巨大的texlive支持,一直不想在服务器上折腾这个。

现在我用的是phplot,一个php绘图库,基本需求能满足,但是绘图控制上不能很顺手,功能也有欠缺,生成的图片质量不高。写的很多,是因为我在问之前,已经Google了好几天了,没有很好的解决方案,所以才来问的。

想问问各位有没有服务器端生成高质量图表图片的经验?大家采用了什么解决办法?

可以变相的通过网页截图来实现把...phantom模拟截取一个动态生成的html的截图,速度挺快的,又能用到所有js的高级特性.出来的图片能够用pipe的方式回传给php的(exec就能接收)

HighChart 不是有个exporting功能吗?用CURL获取PNG不就好啦

上面几个方法好像在性能和稳定性上面都没有很好的保障,我也有这样的需求,坐等方法。

wkhtmltopdf用这个可以将网页转为图片或者pdf

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
