甘特图通过条状图来显示项目、进度和其他时间相关的系统进展的内在关系随着时间变化的情况。
其中,横轴表示时间,纵轴表示任务。线条表示在整个期间上计划和实际的任务完成情况。甘特图可以直观地表明任务计划在什么时候进行,及实际进展与计划要求的对比。
我们也可以使用甘特图来绘制分类的数值区间对比情况,如下图。
为了方便进行演示,这里我们没有使用 Wyndemodata 数据源。
在图表>图表类型中切换图表类型。
将“ 开始时间 ”或者“ 结束时间 ”拖拽至数据字段。因为绑定后下一步还要修改字段数值,所以这里绑定任意字段都可以。
将“ 任务 ”拖拽至分类中。
单击在数据字段绑定的字段,然后在属性设置中修改其数值。将lower 值绑定为“ 开始时间 ”,将upper值绑定为“ 结束时间 ”。
为了使不同的任务显示为不同的颜色,我们将“ 任务 ”也绑定到颜色绑定区中,如下图:
单击设计器上方的预览按钮,预览报表。可以看到甘特图的基本形状已经绘制出来,接下来主要是对外观进行调整。
选中图表横轴区域,然后在属性设置面板的搜索框中输入“ 数据格式 ”快速定位到该属性,然后在下拉列表中选择短日期。
接下来,将横轴的主网格线设置为虚线。
选中纵轴区域,在属性设置面板的搜索框中输入“ 是否显示 ”,然后将坐标轴样式和坐标轴标签都设置为否。
选中图表的标题区域,然后输入标题。

使用甘特图的关键步骤在于数据绑定环节,实现文中开始时第二个示例的关键在于数据绑定。
将产品单价的最大值和最小值作为数值的区间。
