Med-Box Plot (Medbox) - Casio CLASSPAD 330 3.04 User Manual

Hi togram Bar Graph (Hi togram)
A histogram shows the frequency (frequency distribution) of each data class as a rectangular
bar. Classes are on the horizontal axis, while frequency is on the vertical axis.
Graph Parameter Setting (page 7-3-3, 7-3-4)
• [XList] specifies the list that contains the data to be graphed.
• [Freq] specifies the frequency of the data.
A dialog box like the one shown above appears before the graph is drawn.
You can use this dialog box to change the start value (HStart) and step value
(HStep) of the histogram, if you want.
The initial HStart and HStep values on the Set Interval dialog box are set in accordance
with the Stat Window Auto setting. When On is selected for Stat Window Auto, appropriate
values for the graph data are input automatically. When Off is selected, the values that were
displayed the last time the Set Interval dialog box was displayed are input automatically.
