Reverse Vertical property is used to reverse the chart vertically. Below is an example of a chart with the Reverse Vertical property set to false (you can see the X-axis values are oriented normally).

If the Reverse Vertical property is set to true, the chart will be displayed vertically in reverse. Below is an example of a chart with the Reverse Vertical property set to true (you can see the x-axis values sloping downward).

By default, the ReverseVertical property is set to false.
