4.7.2. Histogram
A histogram displays the frequency distribution of the total weighing results (all summary) (including the failed
products) of the selected product number.
To display or print a histogram, the target value and class width must be set beforehand.
Fig.43 Histogram screen
The relation between the border value and class width is shown in the table on the next page.
The target value is placed in class No.9 and frequency is counted for each class.
Clearing a graph is available only for the management level of Supervisor or above.
Note:
Even if the target value is changed during the summary process, the summary will be based on the class width
calculated using the former target value.
Touch the Clear key
to clear the summary process. The class width will be the one calculated using the new
target value.
When the class width is changed, the graph data is deleted automatically and the class width will be updated.
Note:
For details, refer to “8.2.1. Target value” and “8.7.5. Class width.”
