Ranges in JavaScript Bullet Chart control

14 Apr 2021 / 2 minutes to read

’ Ranges ’ represent the quality of a specific range as ‘Good’, ‘Bad’, and ‘Satisfactory’ in the ‘Bullet-chart scale.’ The ‘Ending’ point of the qualitative range is specified by the property End. The ’ Minimum value ’ of a quantitative scale is considered as the starting point for the ‘First range’ and the ‘Previous range’ end points are considered as the starting point for other ranges.
