DMSerie objects represent plot series. Plot can have any number of series. In DM2003, DMPlot object has 8 default (predefined) series. However, you can easily add new ones or delete any serie object using methods of the DMPlot object.
Serie object may be either "regular", or "functional" (parameterized). First category relies on the range of numeric data to calculate points coordinates. Data range (or block) involves reference to the DMContainer object (by default, serie references container from the same data window), positions of X and Y columns, and indices of first and last data element in the linked container. Functional series obtain point coordinates as a result of evaluation X and Y expressions. Parameter in these expressions (named "cx") varied linearly in the range from Min to Max.
For calculation of point position on the drawing plane, serie uses a reference to the axes objects. You may select either primary (default, bottom+left) or secondary (top right) set of axes in any combination.
In addition, serie object has a lot of properties that control various visual attributes of curve lines and points.
