The important Irregular Grid layout characteristics are:

*   The number of rows and columns, the origins, and the irregular grid spacing deltas defines the X/Y grid.
*   Each row and column has its own [RowDelta](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DDataSetGrid.RowDelta.html) / [ColumnDelta](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DDataSetGrid.ColumnDelta.html) value that sets the grid spacing between that row/column and the previous one.
