A useful feature in a current project would be a stacked bar chart visual, where you dynamically can change
For examples a chart displaying number of employees per month (month as the axis of the chart). Selecting a dimension in a slicer would "group" the number of employees and create as stacked bar. Selecting city in the slicer would create stacked bars Employees / City / Month, selecting Gender would create stacked bars Employees / City / Month. This way the user will be able to analyze simple statistics using one single chart.
