org.das2.graph.DasColumn

DasColumn object represents the horizontal position on the canvas.

DasColumn( org.das2.graph.DasCanvas parent, double nMin, double nMax )

create a DasColumn with the normal position and no offsets.

DasColumn( org.das2.graph.DasCanvas canvas, org.das2.graph.DasColumn parent, double nMin, double nMax, double emMin, double emMax, int ptMin, int ptMax )

create a DasColumn

NULL

placeholder for unassigned value.

create

create( org.das2.graph.DasCanvas canvas, org.das2.graph.DasColumn parent, String minStr, String maxStr ) → org.das2.graph.DasColumn

makes a new DasColumn by parsing a string like "100%-5em+3pt" to get the offsets. The three qualifiers are "%", "em", and "pt", but "px" is allowed as well as surely people will use that by mistake. If an offset or the normal position is not specified, then 0 is used.

Parameters

canvas - the canvas for the layout, ignored when a parent DasColumn is used.
parent - if non-null, this DasColumn is specified with respect to parent.
minStr - a string like "0%+5em"
maxStr - a string like "100%-7em"

Returns:

a new DasColumn
