Parameter name: the name of the parameter to be classified.
Number of class: set how many classes the parameter will be classified. It can be increased or
decreased by "▲" or "▼" buttons. When it increases 1, the numbers of both the threshold limit
value at its right and the boundary in the parameter distribution graph will also increase 1, and
the reverse is true. The number of class should be among 1 and 7.
Threshold Limit Value: the value of the corresponding boundary in the parameter distribution
graph.
Parameter distribution graph: take the area distribution graph of QRS wave for example.
Fig.6-10 shows the distributing graph of the wave. The y-axis is the number of QRS wave, the
abscissa is the value of wave. The classified line corresponds to the editor box above. Move the
line by dragging the pane on it to change its threshold limit value. The blue triangle on the left is
the amplification staff gauge, you can change the magnification factor of the y-axis the by
dragging it up and down with the left key of the mouse.
