javascript - d3 "end-of-ticking" event for force layout -

-

i'm working d3's force layout , trying find simple way identify when layout has reached steady state (i.e. when tick function has stopped manipulating position of nodes).

my definition of force looks this...

var force = d3.layout.force()         .friction(frictionvalue)          .theta(thetavalue)         //.alpha(0.1)          .size([width, height])         .gravity(gravityvalue)          .charge(chargevalue)          .on("tick", tick);

then tick function begins...

function tick(e) { ...

i assumed "e" key catching end-point of simulation, since i'm not explicitly passing e tick function on force definition i'm not sure represents or how might able use identify end of simulation. can either shed light on function of e (since i'm not explicitly passing value), or suggest better method simple display "alert(..)" message once force layout simulation has ended?

huge in advance @ all!

you're right, tick wrong event, want end. change last line to

.on("end", function (){     // code });

you can read in api documentation force layout https://github.com/mbostock/d3/wiki/force-layout

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
