Invert the current sort order in a dimension by setting the parameter qReverseSort to true in the dimension.
Example
The first step is to create a chart with one dimension and one measure.
The app, used in this example, gives information about the golf courses in some countries.
1. Create the chart. The paging is composed of the first three lines (qHeight is 3) and first column (qWidth is 1) starting from the top left (qTop and qLeft are set to 0). The dimension is Country (qDimensions/0/qDef/qFieldDefs) and the sorting in the dimension is by ascending alphabetic order (qDimensions/qDef/qSortCriterias/qSortByAscii is 1). The measure is Sum(Holes) (in qMeasures/0/qDef/qDef).

}
The engine returns:

The sorting order in the dimension is ascending.
3. Reverse the sort order (qReverseSort to true).
The client sends:
{

The sorting order in the dimension is now descending.
