Hi,
Yes, it is possible. CanvasJS Charts just take the height and width of its container. So you need to make sure the container’s height is 100%. You can do the same by setting height of both body and html to 100%.
html,body{
height:100%;
}
Here is a JSFiddle that I created.

Here is one related Stackoverflow thread.
Hope this helps.
