For my coffee roaster I want to show the last 20 minutes of the temperature as a chart. Therefore I put a temperature sample to the data bucket every 3 seconds. I´m using the chart widget to show the temperature in the HMI. I want to use fixed y-axis for the temperature from 120...240°C instead of the auto ranging. How can I get this?
The x-axis should be 20 minutes always. The latest 20 minutes should be shown always. The customer should not be able to change x- and y-axis settings.
Is this possible somehow?
