Amcharts

Question

我正在尝试为手机和平板电脑屏幕宽度（小于 766px）制作 Amcharts 条形图

我面临如下问题 -

由于我使用的是免费版的amcharts，所以必须在图表中保留"Js charts by amcharts" link。只有它出现在图表的左侧，与我的标签重叠。我怎样才能把它移到右边和底部？
我希望类别标签位于值条上方，以使其更具可读性。我该怎么做？
我想增加栏之间的间距，使它们更具可读性，如果用户想要单击它们，他们可以轻松地单击预期的栏。

我不想使用 Jquery 并且我是 javascript 的新手。如果您能在 jsfiddle 或片段中展示，将不胜感激。

这是我的 jsfiddle - http://jsfiddle.net/brpjwf8m/ 下面是我的代码片段 -

var chart = AmCharts.makeChart("chartdiv", {

您可以通过在图表配置中设置 creditsPosition 来更改制作人员的位置。 top-left 是默认值，但您也可以使用 top-right、bottom-left 和 bottom-right.

在条形图顶部设置类别标签的唯一方法是使用一个不可见的图形，将 labelText set to "[[category]]" and labelPosition 设置为 inside 用于旋转条形图。例如：

  "graphs": [{
     // invisible graph for the label
    "labelText": "[[category]]",
    "labelPosition": "inside",
    "showBalloon": false,    
    "fillAlphas": 0,
    "lineAlpha": 0,
    "visibleInLegend": false,
    "showAllValueLabels": true, 
    "type": "column",
    "valueField": "visits"
  },
  //regular graph follows
  ]

除了添加虚拟数据外，没有太多方法可以更改列之间的 space，这会使您的列变小。由于您正在利用一个空列，您只需将全局 columnWidth 设置为 1 并调整不可见图形的 columnWidth 使其更小，并通过将 columnSpacing 设置为将两者更靠近0 让事情变得更好一点，让它变得更好一点 spaced out/larger.

下面的演示：

var chart = AmCharts.makeChart("chartdiv", {
  "type": "serial",
  "theme": "light",
  "marginRight": 70,
  "rotate": true,
  "columnSpacing": 0,
  "columnWidth": 1,
  "creditsPosition": "bottom-right",
  "dataProvider": [{
    "country": "USA",
    "visits": 3025,
    "color": "#FF0F00"
  }, {
    "country": "China",
    "visits": 1882,
    "color": "#FF6600"
  }, {
    "country": "Japan",
    "visits": 1809,
    "color": "#FF9E01"
