Returns the number of dimensions in the chart value. A chart value, depending on the chart type, can contain 1 or more dimensional values that define the chart value.
For example, each chart value in a bar chart contains 1 value (defining the height of the bar), line chart values contains 2 dimensions: X and Y, and shape chart values contain 4 dimensions: X, Y, Width, and Height.
Use the Values property to access each dimension in the chart value. The Value property in comparison returns the main (or only) dimension in a chart value - which dimension is returned is based on the chart type.

Note that TRSChartValue descendant classes expose properties, such as X and Y, which are safer to access the specific dimension of the value. You should not count on a specific dimension index to contain a specific property |
