DrawBeforePointsType - property of object tvTrend

Draw type of prediction to the past.

If the viewer is set in the time so that it displays even the first trend value (the first value in the buffer of the tvPoints object), then the prediction allows to draw the line from this point to the past.

The prediction is drawn only by the tvGraph objects with setting the tvGraph.Type property to "Stairs", "StairsHoriz" or "Const(x)".

DrawBeforePointsType As Long
oTrend.DrawBeforePointsType = n
0 (default) - the prediction is not drawn
1 - the prediction is drawn by the horizontal line from the first point to the past
Property access for read and write.

The property is used only if the graphic mode is set.
