A bar graph shows the value of a monitored variable by displaying a bar with variable length. When the value of the variable increases or decreases, the length of the bar increases or decreases accordingly. A bar graph can have a scale and the scale enables you to measure the length of the bar and read the current value of the monitored variable.
There are two bar types that a bar graph can have: a polar bar and a bipolar bar. The polar bar can only move at one end, but the bipolar bar can move both ends. The bar and the scale can be displayed in any of the following four directions:

Type	Upward	Downward	Leftward	Rightward
Polar Bar (Monitored Value = 60)
Bipolar Bar (Monitored Value = 60 　Middle Point = 50)

A bar graph can also have a scale, forward markers, backward markers and a percentage display.

Note:
* If the bar graph is upward or downward, the scale and forward/backward markers will be located on the left or right sides.
* If the bar graph is leftward or rightward, the scale and forward/backward markers will be located at the top or bottom.

You can complete all the settings of a bar graph in the Bar Graph property sheet. This sheet contains the following six pages.
