Insights Hub Line widget and IoT Chart widget of Monitor displays data in different ways

When I place both Line widget and IoT Chart widget to the Monitor dashboard and specify the same data source and the same time range, the charts show data in different shapes.

I don't know why.

Line widget:

IoT Chart widget:

Monitor's dashboard is a powerful tool to visualize Insights Hub data in various ways.

Both Line widget and IoT Chart widget are suitable for displaying TimeSeries data.

The logic for displaying large time range such as day-based are different.

Both uses IoT TS Aggregates service API:

*IoT Time Series Aggregates Service

Line widget uses 

-the average of the values during the interval

IoT Chart widget uses 

-value and time of the first data point of the interval

-value and time of the last data point of the interval

-value and time of the minimum data point during the interval

-value and time of the maximum data point during the interval

Line widget is suitable for monitoring the trend overview of timeseries data.

IoT Chart widget is suitable for monitoring the trend and also detecting unexpected small and/or large values.

You can select a widget based on your objective of visualizing data.
