I updated the code https://gist.github.com/jhuenges/814b60d80c96db014e045f2207fc1814 Can you tell me what the console.log in line 89 says?

You need to change Template.template.onRendered

sorry I do not have pay attention to this detail

[jhuenges]

I ll take a look at it in a couple of hours.

[jhuenges]

This should (hopefully) work now: https://gist.github.com/jhuenges/814b60d80c96db014e045f2207fc1814 (rename the template names ;) )

I do not know what to say, this does not seem works :$

ok, changed div id my bad return to me "no data to display"

[jhuenges]

Is there data in the collection? Add console.log(buyhistoryMin, buyhistoryMax, sellhistoryMin, sellhistoryMax) here and tell me what is in the array

[VeilleurTrytoFix]

array return is good, and collection is not empty

[jhuenges]

Okay, found the problem. For some reason you store the values of min, max, avg and so on as an array of strings and here. That is why the code doesnt work. I would suggest to change the server code because storing simple numbers should be much easier and makes a lot more sense. You would need something like

var typebuymax = parseFloat(typebuy[0].max[0]);
...

[VeilleurTrytoFix]

I changed as you have advised me (I emptied the previous entry), I have no data to display again

[jhuenges]

Hm, that NaN shouldnt be there. Is this in every array?

[jhuenges]

Okay ... :D Change

new Date(obj.date).getTime()

to

new Date(obj.createdAt).getTime()

here and here

You know the difference between " meteor add maazalik:highcharts" and "meteor add highcharts:highcharts-meteor" ?
