修改数据格式顾名思义即修改数据的显示格式。对数据格式的修改最终将会体现在图表的报表图表数据标签、鼠标提示标签、数据表及KPI指标卡等位置。
如下图所示,将数据格式调整为百分比后的显示效果。
与字段重命名类似,数据格式也同样可以在两个地方进行修改。一是在数据集/数据模型字段上,二是在组件字段上。
这两种方法的区别是:对数据集/数据模型中字段进行的操作是面向所有组件的,也即所有使用该字段的组件中都会发生变化;而对组件字段进行的操作仅在当前组件生效。
在字段上下文菜单中选择设置格式,弹出字段格式化对话框,可对字段的展示格式进行格式化。
例如,我们对“ 折扣 ”字段进行数值格式设置。单击字段后的设置按钮,选择设置格式。
(为了方便讲解修改字段格式后的效果,我们将柱状图的报表图表数据标签显示出来了。)
选择“ 百分比 ”,并设置小数位数为“ 1 ”,然后单击确定。
预览效果如下,可见所有使用该字段的组件中均发生了变化。
同样的操作,我们在柱状图组件的绑定字段中进行操作来对比看看。
选中组件,在组件绑定区域单击数值 旁边的 图标,在下拉菜单中选择数据格式,即可在弹出的格式化字段对话框中对数值进行格式化。
在弹出的格式化窗口中,可以对数据字段进行格式化设置。如显示为百分比、控制小数位数等。
选择“ 百分比 ”,并设置小数位数为“ 1 ”,然后单击确定。
预览效果如下,可见仅柱状图中的数据标注发生了变化,而折线图组件中并未受到影响。
