Explanation

(1)Set initial values.
(2)Display bar chart when execute measurement.
(3)Get the judgement result of selected processing unit, and increment measurement count.
(4)Increment OK count or NG count by the judgement result.
(5)Clear the setting of chart control.
(6)Set the measurement value (measurement count, OK count, NG count) to chart control.
(7)Refresh scales of x-axis and y-axis of the chart.
