A log value displays one or many trend log values as numerical values.
The colors and calculation method of every log can be changed.
You can configure the color so that different values and value ranges are displayed in different colors. You can also add icons in front of the value to make the values easier to read.
For example, you want to create a log value that displays two logs, one called Cooling and one called Heating. The values in cooling between 0 and 10 will be displayed in dark blue and the values from 10 to 15 will be displayed in light blue. The values in Heating between 15 and 20 will be displayed in light red and the values from 15 to 30 will be displayed in dark red.
First start by adding the two logs Cooling and Heating to the gauge.
Edit the log Cooling. Add two guides in the Guide field and configure them as follows:
Value = 10 and the color dark blue. This makes the color range for all values up to 10 dark blue.
Value = 15 and the color light blue. This makes the color range for all values over 15 light blue.
Edit the variable Heating:
Value = 20 and the color light red. This makes the color range for all values up to 20 light red.
Value = 30 and the color dark red. This makes the color range for all values over 20 dark red.
