5.2 Analysts should choose the appropriate measurement Interval 

Selecting a suitable time interval is a must for line charts as it can suggest proper information to the analysts. For example, if you are selecting monthly data as the interval to create a temporal data chart then you will find it long to see where the trend is going.
