A trend can have multiple filter areas. Different limit settings can be assigned for each filter area.

If trend filters are defined in a trend, they are visualized in groups. When the trend is expanded, it therefore looks different than trends with no filter. Trends with filters have a separate section for each filter area. These sections can be shown or hidden and contain the data for the filtered trend. This means that there can be several trend lines with the same color. Selecting the Combine signals checkbox, which can be found by clicking on the button with three dots, enables the original trend line with no filters to be displayed.
