gojs - how to set nodespacing in timeline layout -

i working on gojs timeline sample(http://gojs.net/latest/samples/timeline.html) default functionality based on dates.i have added more number of nodes existing nodes due overlapping each other. how set nodespacing in layout.

in prototype code in example, find part, rewrite:

var bar = line.findobject("bar");       var length = 100;       var cellw = 100;       if (bar && numweeks > 0) {         length = bar.actualbounds.width;         cellw = length / numweeks;         // set size of each cell         bar.gridcellsize = new go.size(cellw, bar.gridcellsize.height);         // offset account starting on non-first day of week         bar.gridorigin = new go.point(convertdatetox(firstsunday), bar.gridorigin.y);       } 

here have 3 options (actually two, 3. suggestion):

1. change vars:

   var length = /*the length want bar have (you take number of cells * cellw below)*/ var cellw = /*the length want each cell have*/ 

2. make configurable:

   do

   timelinelayout.prototype.setcellw = function(newcellw){ this.cellw = newcellw; } 

   then reference in part shown above.

3. use gridlayout instead: here see if sufficient needs.
