Hi.
You can use this tutorial as a reference: https://randomnerdtutorials.com/esp32-esp8266-dht-temperature-and-humidity-oled-display/
You need to change the sensor.

Regards,
Sara

Hi.
We don’t have any tutorials for bar charts.
You can use chart.js library, like we do in this tutorial: https://randomnerdtutorials.com/esp32-plot-readings-charts-multiple/
But, use this bar graph example as a reference: https://www.chartjs.org/docs/latest/samples/bar/horizontal.html

Sara

Hi Sara I would like a horizontal bar graph, possibly from xy coordinates if possible.

Hi.
Can you be a little more specific about what you want to achieve?
You want to display a different type of graph/chart?
Regards,
Sara

I have been a recipient of your regular emails for many years, it is only recently that I have the time to try some of your great tutorials. I have the ESP8266 web server running but have run into a problem trying to make a horizontal graph point read from an interger value in the esp.
I dont really want a bar graph but that would do. I seem to have got lost in the code somewhere.
Do you have any tutorials along this line?

Hello Sara,
saw your excellent example just by chance and wondered about your code snippet inside the loop.
In case of asynchronous webservers I made very bad experience with independent loop programming because of possible timing conflicts, expecially in RGB-LED controlling. I got not only an occasionally delayed response but sometimes even uncontrolled and awful rebooting. So as a rule of thumb I never touch the loop in an asynchronous webserver.
Thanks for any comments.
Hearty regards from Germany
Hans
