In reply to Tony. Never mind - seems to have been a memory configuration setup problem that I now can't repeat. Please delete these comments?

I’ve been working with this sketch for a little while now. It works fine when you simply load the sketch to an ESP8266 and connect to it via a web browser.

However, clicking the Refresh button on the web browser while the chart is running causes the ESP8266 to throw an exception and restart.

Has anyone else seen this behavior?

Another possibility is to set the actual Timezone, like
time:{
timezone: ‘Europe/Amsterdam’
}

I think that that’s the first time that I’ve heard some say “There’s too many options!”…!

Hi.
Unfortunately, we don’t have any projects using that method.

Thank you very much, Sara, for your kind response. I’ve searched your website a lot and haven’t seen the tutorial I’m referring to. Maybe I’m confused, but it seems to me that it is a web server that displays a simple graph using SVG, without using filesSystem or Charts.js but rather http://www.w3.org/2000/svg.
I have developed the idea but I am looking for the source for reference.
Very grateful for the excellent tutorials.
Thank you and happy new year

Hi.
Is it this one https://randomnerdtutorials.com/esp32-esp8266-plot-chart-web-server/?
Can you give more details about that project.
We have several with charts.

Hello, Sara and Rui.
I tried to find one of your projects where the 8266 displayed a simple graph using SVG.
Can you give me the link, please?
Thank you very much and congratulations for your excellent work.
