谷歌图表API平滑折线图 [英] Google Charts API Smooth Line Chart

问题描述

有人知道如何用平滑线条而不是锯齿线创建折线图吗？

我认为我的图表对于最终用户平滑线。

以下是一个示例网址：

http://chart.apis.google.com/chart?chxr=0,0,46&chxt=y& ; CHS = 300x225的&安培; CHT = LC&安培; CHCO = 3D7930&安培; CHD = S：MNPRSYVUSSMNQRVfXXSPPM&安培; CHG = 14.3，-1,1,1&安培;的Chls = 2,4,0&安培; CHM = B，C5D4B5BB，0,0,0

解决方案

我简单地使用了

  var options = {smoothLine：true，} 
 
 var chart = new google.visualization.LineChart（document.getElementById（'some_id'））; 
 chart.draw（data，options）; 
  

免责声明：如果您有非常尖锐的拐角，舍入/平滑可能会引起误解（例如，如果您的曲线快速到f（x）= 0，它可以变成负值以适应角落。

Does anyone know how to create a line chart with a smooth line instead of a jagged line?

I think my chart would present much better to end users with a smooth line.

Here's an example URL:

http://chart.apis.google.com/chart?chxr=0,0,46&chxt=y&chs=300x225&cht=lc&chco=3D7930&chd=s:MNPRSYVUSSMNQRVfXXSPPM&chg=14.3,-1,1,1&chls=2,4,0&chm=B,C5D4B5BB,0,0,0

解决方案

I simply used

var options = {smoothLine: true,}

  var chart = new google.visualization.LineChart(document.getElementById('some_id'));
  chart.draw(data, options);

Disclaimer: if you have very sharp corners the rounding/smoothing can be misleading (for ex. if your curve goes quickly to f(x) = 0 it can become negative to fit the corner.
