Manages Markers.
Use the TMarker constructor to create a marker.
The parameters x
and y
are the marker coordinates and marker
is the marker type.
Use the TPolyMarker to create an array on N points in a 2D space. At each point x[i]
, y[i]
a marker is drawn.
Use the TAttMarker class to change the attributes color, style and size of a marker.
Example
TAttMarker::SetMarkerSize(size)
method to set the size
of a marker. Public Types | |
