Hmm, looks like Highcharts are too slow when loaded with 48 hrs worth of realtime data at 1 minute updates

Seems OK here?

Hi Mark,

The graphs are a bit slow on the initial load and fine after that. The graphs not any slower than the WU version of these graphs I have seen other web pages.

The initial data download can be just short of 2 seconds, but subsequent graph data loads are about 300ms (for me, but I'm fairly local ). Highcharts then takes about 600ms to render the graph (the Wind Direction plot takes longer because it is drawing all the point 'graphics'). So just around the 'rule' of 3 seconds for a page load.

Edit: This evening I have being playing around with my web server caching responses for various pages - it will ease the load on my laptop, but I may have taken them too far, we'll see...

OK, I've made some changes, most of the graphs now only pull back every 10th record out of the realtime table.

The Wind Direction graph has a few 'optimisations' applied (switching off stuff like mouse tracking and popup data for each point) and pulls back every other record from the table.

Any quicker/smoother?

You may have to flush your browser caches to pick up the new script, I managed to get a one month cache retention on the scripts for a while

Seems fine here about 1-2 second load time.

It's good for me too. When clicking on each variable in quick succession it is very slick, with just a slight stall on wind direction. On the whole a nice piece of presentation that is a joy to look at and explore. BTW my pc is fairly crap in terms of speed.

Lot faster than yesterday.

Added a Solar/UV Graph - but I don't have any data

Works fine hand fast on my android tablet , read hand without An h , autocorrection s..

Does the PHP use the NEW 2.0 import file timestamps?

It does.

Converted my DB over.. just waiting for graphs release
I assume this will be using realtime data from mysql.

My current 24 hour graph is using a .txt file.

Yes they do, I have also converted my 6hr graph to use the MySQL table too, the text log file is now gone.

Awesome, sounds good to me.
