<div id="divId_graph" ></div>
<div class="graph" id="graph" style="margin-top:-15px"></div>
controller.js:
$('#graph').svg({ onLoad:drawIntro});
The drawIntro is a function which calculate values.It's not calling when I recall the function with in same page by change some input values.
$watchfor changes and redraw when a change is detected. Alternatively you could use an event listener and emit/broadcast the appropriate event to trigger a redraw.
