Create Control Chart Manually
Explanation
This activity is used to create a control chart manually for a specific control
plan line (data point).
- p Chart - Gives information about the proportion of
nonconforming units.
- np Chart - Gives information about the number of nonconforming
units.
- c Chart - Gives information about the number of nonconformities.
- u Chart - Gives information about the number of nonconformities
per unit.
- Xbar and R Chart - Gives information about the average
and the range of the result set of each analysis selected in the graph.
- Xbar and S Chart - Gives information about the average
and the standard deviation of the result set of each analysis selected in
the graph.
- X and MR Chart - Gives information about individual
results and moving ranges for each analysis selected in the graph.
An analysis will not be included in creating a chart if any of the following
conditions exist:
- The status of the data point is Incomplete.
- The analysis result is in the Cancelled status.
- The defined fixed sample size of the data point and the resulting sample
size of the analysis results do not match. (This does not apply for the
p chart and u chart.)
To create a control chart for a specific data point click Create
SPC Chart on the Control Plan Lines tab,
eventually update the information displayed in the Create SPC
Chart dialog and click OK.
Prerequisites
- To create a control chart for a specific control plan line, the corresponding
control plan must exist, with at least two created analyses in status
