View type of trend.
- Continuous, data points of the tvPoints
object are connected by single line
- Stairs, data points of the tvPoints
object are connected by horizontal and vertical pointed line
- Stairs, it differs from the previous value thereby that vertical lines are not drawn
"Bar" - Simple bar

When the object is created, the value of this property is copied from the PmgTrendViewer.GraphInit
If the tvGraph
object draws even the latest
, or the oldest
data point from all points read in the tvPoints
object, then the tvTrend.DrawAfterPointsType
properties specify if the tvGraph
object has to draw even the predictive trend to the future
, or to the past
(the predictive trend is possible only at the types "Stairs"
and it means drawing the horizontal line to the future, or to the past).
