R shiny / rCharts / nvd3：覆盖固定宽度和高度？

Question

我意识到我为我的 nvd3 图表（包括添加我自己的 css）设置宽度和高度的所有尝试都被破坏了通过一些内联 css:

<style>
.rChart {width: 800px; height: 400px}
</style>

怎么办？我不知道这是从哪里来的，也不知道如何阻止它被输出。此外，我想不出任何人为什么会首先为情节设置固定维度的任何原因...

更新：我不知道下面的每个评论都有一个 renderChart2()。我试过如下：

  output$testChart <- renderChart2({

    n1 <- nPlot(xxx~yyy, data = xyz, type = 'discreteBarChart')
    n1$xAxis(axisLabel = "Heading")
    #bug with nv.d3.js - without width, the ylabel is off the chart area and invisible?
    n1$yAxis(axisLabel = "label", width = 40)
    n1$set(title = "Title")
    n1$chart(width=1600, height=800, tooltipContent = "#! function(key, x, y, e){ 
  return 'x: ' + e.point.x+ '<br/>  y: ' + y 
} !#")
    n1$addParams(dom = 'testChart') #need this line, else it doesn't get rendered in dom!
    return(n1)

  })

我在 html 输出中得到了这个（用 firebug 检查）：

<div class="shiny-html-output rChart Nvd3 shiny-bound-output" id="testChart"><style>.rChart {width: 800px; height: 400px} </style>

<div class="rChart nvd3" id="testChart"></div>
<script type="text/javascript">
 $(document).ready(function(){
      drawtestChart()
    });
    function drawtestChart(){  
      var opts = {
 "dom": "testChart",
"width":    800,
"height":    400,
...(etc)...

是的，我有点不知所云..

Answer 1

尝试更改：

n1$chart(width=1600, height=800, tooltipContent = "#! function(key, x, y, e)

至：

n1$set(width=1600, height=800, tooltipContent = "#! function(key, x, y, e)
