Home Forums Chart Support Graph a CSV file Reply To: Graph a CSV file


Preface – I copied and pasted the first answer and just changed the url:”data.csv” and nothing else. I did do something different and that was to put it in a separate file from my index.php file for my own sanity. (I don’t like having javascript in the same file as my html. Might just be me, but still)

Anyways, back to the point of this post :-)

I was doing some testing with this method of graphing a .csv and checked the console. Well apparently, the javascript I copied and pasted threw an error in the console. The error is : Uncaught TypeError: Cannot read property ‘getContext’ of null

As I really am noobish in Javascript, what is this supposed to mean? Is it nothing? Normally errors in programming are nothing, but still worries me :-)
