Can anyone render chart using iron router or wihout reload the page

i am using highchart but chart can show only i reload the page.

I am not sure if my reply is relevant for you, for instance I haven’t worked with iron-router in this context. I have created a Meteor-Chart.js-demo
For me, the main lesson was: First time the chart is created in the .onRendered hook of the template. After that the chart is updated in .helpers of the template.
