Examples
DropLineStyle(1;all;1;blue;gray)
Description
As an option, drop lines can be added to scatter, bubble, line, bar and area charts. A total of 4 functions are available for this. They serve to:
- design the drop lines
- define a reference point
- define a reference line
- define a set of reference series
For all 4 functions DropLineStyle(), DropLineReferencePoint() , DropLineReferenceLine() and DropLineReferenceSeries() the series index is defined as the 1st argument. If no series index is defined or if seriesIndex = all is set, the respective function refers to all data series. The 2nd argument dropLineAxisIndex defines the direction of the drop lines. When dropLineAxisIndex = x, the drop lines refer to the x-axis; when dropLineAxisIndex = y, they refer to the y-axis. If no axis index is defined or if dropLineAxisIndex = all, drop lines are drawn in the direction of both the x-axis and y-axis. The stroke and color of the drop lines can be varied using the arguments stroke, color and colorVariant. Unless otherwise defined, drop lines are gray, 1-pixel wide lines.
