Wind Direction scatter chart not rendering in browser
Evening all
I have a rather strange problem with one of the standard charts only.
Since resolving my data logging hardware problem last week, things have gone very well. I managed to get Cumulus all running locally (build 3089) on the R Pi, then organised a remote web host (with krystal.uk), and got the "Simple website" configuration uploaded and working. I looked at all pages (both in the local interface and on the web) from my desktop PC and initially all worked fine.
Then as I continued to test the next day, the wind direction chart suddenly stopped displaying data points. Around then I picked up the message about build 3091, so did a fresh install on Monday 17th. Again the charts worked OK. The following day, sure enough, it had disappeared again, but I didn't think too much about it. However, now that I have finished testing all the basics, and want to start thinking about some simple customisation, I thought I should look into this issue a bit more, which has not resolved itself.
I randomly tried accessing my site (again both local interface directly on the R Pi, and also the website) from an Android tablet and was surprised to see the chart data displayed fine in either Chrome or the Samsung browser. So I checked different browsers on my PC, and found that my default Chrome browser still does not display the data points (although it did on first days of install with both builds as per above), and neither does Microsoft Edge. It does however work fine in a legacy IE11 browser!
Has anyone come across this before, or have any idea what to check? I'm not attaching logs but happy to attach if anyone thinks any are relevant. PC screenshots attached of both Chrome and IE11. The offending page is here (navigate to Wind Dir option):

Re: Wind Direction scatter chart not rendering in browser
Yes, there is a thread on this issue. If you read that you may understand it is google chrome which is the cause. If you switch off hardware acceleration the problem may be gone.

Re: Wind Direction scatter chart not rendering in browser
Thanks for that pointer Hans. It is a long and varied thread (which probably explains why my forum search strings didn't pick it up), but it has opened my eyes to other interesting parts of this forum!
Absolutely right, turning acceleration off does fix the problem in Chrome, and also in Edge (which is of course now Chromium-based)! Chrome on Android is clearly a different beast, which is why that is fine I guess. As meteo19 commented, this is not ideal, as site visitors will most likely have this feature turned on. I guess it is probably wise for now to add a suitable comment above the wind direction graph on my site, which I will look at in due course.
Thanks again!

Re: Wind Direction scatter chart not rendering in browser
Your wind direction works fine and loads fast for me, both on Chromium based Edge and Chrome itself. (hardware acceleration on)

Re: Wind Direction scatter chart not rendering in browser
Thanks for the confirmation. I assume you have hardware acceleration turned off as I now do.
Like your website by the way! One of the ones I had been looking at in collecting ideas for how I might customise.
Cheers
Colin

Re: Wind Direction scatter chart not rendering in browser
Thanks for the kind words.
Nope, it's on. I never turn hardware acceleration off in my browsers, it creates more problems with other sites.

Re: Wind Direction scatter chart not rendering in browser
I thought the scripts were changed a few releases back to solve the hardware acceleration issue.

Re: Wind Direction scatter chart not rendering in browser
@ConligWX, @Mapanz: It appears not to be as straight forward as you may think. It appears to be a confusing interaction between hardware acceleration, WebGL and the type of graphics card (if I read the articles I found). And whichever corner you take, if you switch hardware acceleration off if you have the problem (which both of you apparently don't have), the problem goes away and the scatter always displays. So, the fact that you don't see the problem does not say anything about the situation at @colin99.

Re: Wind Direction scatter chart not rendering in browser
yes HansR, it may not say anything about him, but as we are site visitors - he said "site visitors will most likely have this feature turned on" which we have, didn't affect us. that's why myself and Mapanz replied.HansR wrote: ↑Fri 21 Aug 2020 11:42 am @ConligWX, @Mapanz: It appears not to be as straight forward as you may think.

Re: Wind Direction scatter chart not rendering in browser
Hi everyone
Very interesting! I'm sure Hans is right and I am probably not the only one experiencing this. I appreciate it most likely will not be solved though.
For me it is very repeatable now I know the cause. Hardware Acceleration on equals no data displayed on this one particular graph in Chrome on my PC only (and latest Edge version which is Chrome-based anyway). Turn it off or use other browsers or devices and all is fine. Re the other potential elements in the "Interaction" I have an Nvidia 9600 based graphics card with latest available driver (dated 2016) running under Windows 10 Pro, Build 19041. I'm assuming WebGL is used within Cumulus.
If anyone would like me to supply any other information or try anything else please shout. Otherwise happy to move on!
Thanks for the help.
