The SA_Trend_SinglePen symbol can include a meter at the right border of the trend grid. The trend shows the meter's continuous measured value over the trend period.
The meter is similar to the general purpose SA_Meters symbol with MeterType Wizard option to set eight different types of meters. The SA_Trend_SinglePen symbol includes the same visual symbol components as the SA_Meters symbol.
