画汉字很容易,imagettftext 就可轻松完成
但我不可能替你去组织数据
我现在想获取到比如5.4里面,我又分成三个属性,并且显示每个立柱的名字,请问该如何改进代码。
并且下面的类型个数不限制,比如有钢管,铝管,铜管,金管,。。。。。有若干个。
但是属性只有三个。。。。每个都为整数。。。 纵坐标都会画,照着改下就能画出横坐标了撒。画数据柱可以用两个循环嵌套,外面循环n次,n为管的种类数,并设置每个种类间隔长度;里面循环就画条形图呗,无间隔。然后计算好图的高度坐标,写上号码字符就行了啊。
这样图形 jquery 插件一大堆! 用什么php绘画.
就算是php也有图形包啊

请高人指点啊,本人菜鸟一个。。。

看过这个,正在研究用法。。
有高人告诉用法么?
看看API,找找他们的例子,拷贝过来修改下参数就可以。
JS图表库用这个很方便,应该有符合你的案例:Highcharts
