pentaho - 在 CDE 仪表板中编辑工具提示

Question

如何在 CDE 仪表板中编辑默认工具提示？如果饼图的工具提示是这样的：

Series: Fuel
Category : D
Value: 0.15

我想将系列、类别、值更改为其他标题。谢谢

这是 pentaho 论坛中的链接：http ://forums.pentaho.com/showthread.php?141559-Edit-Tooltip-in-CDE-dashboard

我试过了，它奏效了。

将 Pentaho 论坛的原始答案复制到 Mogsdad 建议的此处：

每个值在工具提示中显示的标签是相应维度的标签。

如果要显示完全不同的工具提示，则必须指定选项 tooltipFormat。

如果您只想更改显示的标签，则只需更改尺寸的标签。

因为可以使用任意名称定义维度（即使默认名称是众所周知的），所以没有固定的 CDE 属性。名称必须在 JS 代码中更改。

更改默认尺寸的标签

将以下代码添加到 CDE 图表组件的 postFetch 处理程序：

代码：

function f(data) {
  // Change the labels of the default dimensions
  // See http://www.webdetails.pt/charts/jsdoc/symbols/pvc.options.charts.Chart.html#dimensions
  this.chartDefinition.dimensions = {
    series:     {label: "Product Family"},
    category: {label: "Period"},
    value:      {label: "Sales" }
  };
  return data;
}

更改尺寸的名称和标签

也可以更改维度的名称以匹配相应业务概念的名称：

代码：

function f(data) {
   var options = this.chartDefinition;
   // It is not necessary to explicitly define dimensions
   // They are created automatically, with appropriate default properties, 
   // when referring to their names in certain other properties.
   // But we can define them anyway, if we want to change the default labels.
   // Default labels are taken from the data source, when possible,
   // or derived from the dimensions' names.
   // See http://www.webdetails.pt/charts/jsdo...tml#dimensions
   this.chartDefinition.dimensions = {
     productFamily: {label: "Product Family"},
     period: {label: "Period"},
     sales:  {label: "Sales" }
   };
   // MAP columns in the data source to corresponding dimensions
   // See http://www.webdetails.pt/charts/jsdo...t.html#readers
   options.readers = [{names: "productFamily, period, sales"}];
   // MAP dimensions to the chart's Visual Roles
   // See http://www.webdetails.pt/charts/jsdo...ml#visualRoles
   // The following can also be set as CDE properties.
   // The "series" role receives the data of the "productFamily" dimension
   // See http://www.webdetails.pt/charts/jsdo...tml#seriesRole
   options.seriesRole = "productFamily";
   // The "category" role receives the data of the "period" dimension
   // See http://www.webdetails.pt/charts/jsdo...l#categoryRole
   options.categoryRole = "period";
   // The "value" role receives the data of the "sales" dimension
   // See http://www.webdetails.pt/charts/jsdo...html#valueRole
   options.valueRole = "sales";
   return data;
}

要更改 CDEdashboard 工具提示，请将此功能添加到 Post Fetch。

function f(data) {    
    this.chartDefinition.dimensions = {
        series: {isHidden: true},
        category: {label: "Category"},
        value:      {label: "Value" }
    };   
    return data;
}
