Hi Gary,

All working thanks to your hints.

It did not like these two lines in graphs.html: -




I dropped the ../ in front and hey presto! I knew it would be something so
obvious that I had not spotted.

Thanks once again.

Ian

Gary,

Thanks for your detailed response. It is on my test server which it is no
public facing. I will give it another go using your hints. If I continue to
fail I will install on my public server to let you have a look.

Thanks again,
Ian

[weewx-user] Re: Trouble setting up Highcharts

[gjr80]

Ian,

The two main parts to the Highcharts extension are the WeeWX skin that 
generates the json format data file and the html/javascript that displays 
the plot(s). WeeWX only real involvement is the generation of the json 
format data file, nothing fancy there and 3.9.1 should be compatible with 
the skin. The only issue I can think of here is perhaps the new skin config 
sitting hierarchy introduced in WeeWX 3.9.0, but that would likely only (at 
worst) result in unexpected number formats or units. If your json file is 
being generated without error it should be usable (a useful tool for 
checking your json output is one of the online json validators, I use 
jsonlint.com, just open the validator page, copy the contents f your json 
format file and paste into the validator, hit the button and it gives you a 
yay or nay.

Given your description, it sounds like a javascript issue on your page. 
Easiest way to troubleshoot Highcharts is to through your browsers 
console/web console. where you can see any javascript errors. Where to find 
the console is browser dependent, I mainly use Firefox and it is under Web 
Developer -> Web Console or Web Developer -> Browser Console.Under Chrome 
it is under More Tools -> Developer Tools. Once you have the console open, 
clear it if it has any content and then force a reload of your html. Then 
its a case of looking for any (relevant) errors in the console output. 
Likely errors are a script (including Highcharts) loaded by the page being 
unable to be found, a script being unable to locate a file or Highcharts 
choking on incorrect data/settings in a file.

If your graph page is public facing if you are happy to give us the address 
I can look at the javascript console myself.

Gary
