Dygraphs not working on iOS

[Didier Juges]

My site http://www.eds-fl.com/test/plot.php?file=-70.183.228.107.csv&length=day
Works fine under android and Windows (any browser) but not on my iPad mini (either chrome or safari)

Only the grid is displayed (sometimes, at some other times, nothing at all is shown)

Any clue as to what is going on would be welcome.
Thanks in advance

Did you ever solve this?

I'm having the same problem.

No, have not had much time to work on it, but please stay in touch if you find a fix, I will do the same...

Not sure, I made my first post in September 2016, and that was shortly after installing dygraphs and noticed the problem, so the version I use is whatever version was current then. 

I have not tried to upgrade since because there was no response on the forum so I pretty much gave up on iOS.

Interestingly, the examples on the dygraph page all work with iOS, so I am not sure what I could have done to break it.

Hello Everyone,

not sure if this is still an open threat, but I had the same problem with dygraphs. And I could solve it as follows:

My website was working on desktop systems using Chrome, FF, as well as with any Android browser I tested.

But It did not show any graphs on any iOS-Browser, nor on macOs using Safari. Hence it appears to be connected to Apple's browser engine,

To pinpoint the problem I used the Safari Developer Console (activate in Preferences>Advanced), and then in the menu Develop -> Show JavaScript Console.

This revealed a problem with the Date format. ("x not a valid Date"). 

I am using the format YYYY-MM-DD which causes the problem. See also here: https://stackoverflow.com/questions/3085937/safari-js-cannot-parse-yyyy-mm-dd-date-format

Hence I converted my data to the format YYYY/MM/DD using the PHP str_replace() function (see here https://www.w3schools.com/PHP/func_string_str_replace.asp ) to build my html-page.

Now it is working on ALL platforms and all browsers.

Hope that helps.
