chart in a bootstrap tab

[shlatchz]

After hours of debugging I noticed that in the function:

function getChildrenByClassname(childrens, className) {

when it's called by:

height -= getChildrenByClassname(childrens, 'ac-title')[0].clientHeight;

In the following part:

for (var i in childrens) {

The "i" receives not just 0,1,2 but also many other strings which are not numbers. Can you please change it to:

for (var i = 0; i < childrens.length; i++) {

Instead? thanks!
