问题描述
我想创建一个y轴从0开始的图形。我的值都不为0。我怎么做在graphael中这样做？
I wish to create a graph whose y-axis starts at 0. None of my values are 0 though. How do i go about doing that in graphael ?
作为扩展，如何创建一个y轴的图形，其最大值是所提供数据中最大值的两倍？
As an extension, how can I create a graph with a y-axis whose maximum value is, lets say, twice the maximum value in the provided data ?
推荐答案
我不知道这是不是太晚了，但我一直在努力与gRaphael自己，并遇到一个解决方案，可能工作您。没有明显或干净的方式来做到这一点，但我发现了一个体面的黑客。
I don't know if this is too late but I've been struggling with gRaphael myself and came across a solution that might work for you. There's no obvious or clean way to do this but I've found a decent hack for it.
你可以添加另一个y值数组（第一个是0和最后为您的最大值的2倍），并使用颜色选项指定此行的颜色为透明。
You can add in another array of y values (the first being 0 and last being 2x your max value) and specify the color for this line to be transparent using the colors option.
我创建了一个小提琴，以便您可以看到我的意思：
I've created a fiddle so you can see what I mean: jsFiddle example
第一个图表是您当前的图表，第二个图表显示第二组y值的添加。
The first chart is what you currently have and the second shows the addition of the second set of y values.
