Same with a shaded area. The same option could mean that the surface is widened. In the example, to the position "01/01/2012" to "31/12/2013".
An other alternativ is that the user could use "virtual spaces". I.e. as it can be done for example in the command "addarrow"
Code: Select all
WfCreate(page=a) a 2010 2017
Graph g1.line x1 x2
g1.draw(shade, bottom) 2012 2013
g1.draw(Line, bottom) 2016
