Hi Hazelnutuz, the system automatically creates a chart for each DS18B20 sensor plugged in. If you unplug it the chart remains and I haven't added an option to delete it but that should be in the next update. If you want to remove a chart from the dashboard go to "charts" screen and at the top is checkbox to hide/show each chart.
At this point to clear a log you need to do it in the database. Here's how you do it.
Run phpMyAdmin to access the database.
Add /phpmyadmin/ to your Pi IP address like below.
http://192.168.1.45/phpmyadmin/
Username = root
Password = robotank
You'll see 4 databases, the first 3 don't mess with, the robotank database is the one, click on it and it'll expand on the left side.
At the top you'll see some tables with a name similar to 00000b90e26a_C There will be 2 tables with the same name but one ends in C and the other F for Celsius and Fahrenheit.
Click on one of them and at click the "operations" tab along the top.
At the far right side you'll see a link "Empty the table (TRUNCATE)" click and and confirm.
Do the same for all the temp sensor tables. At some point this will be done through the interface.
