# Attributes Chart Setup Form

The following form is used to configure Attributes Control Charts. On this form you can select the type of chart (p, np, c, or u), the method to use to calculate control limits and the centerline, axis labels, and the number of standard errors to use.

### Column/Reference Selection

- The Columns tab allows selection of multiple variables in separate columns.
- The Reference tab allows selection of a single variable grouped by multiple variables.

### Speed Buttons

These buttons provide quick access to the following tasks.

- Returns to the
__Main Form__. - Opens a Data File.
- Displays the
__Data Editor__. - Copies Selection to the clipboard.
- Pastes text from the clipboard
- Enlarges/Reduces Form size for easier viewing.
- Brings up the
__Main Form__. - Brings up the Help file.
- Hides the form.

### Menu

**File**: Open or edit a data file, select the Process If options, or return to the Main Form.**Edit**: Copies or pastes selected text.**View**: Provides the ability to enlarge the Form size for easier viewing.**Help**: Calls up this file.

### Control Chart Type

- p chart for binomial proportion data
- np chart for binomial count data
- c chart for Poisson count data
- u chart for Poisson ratio data

### Data Variables

### Measures

### Sample Size

### Set Variable

Sets do not need to be contiguous. In other words, values with Set=1 can be followed by values with Set=2, which can be followed by values with Set=1. All values with Set=1 will then be used to generate the limits and centerlines for all values of Set=1. This will allow you to separate a middle section.

### Constant Sample Size Selection

If a c chart is being generated, and the sample size is constant, a "1" can be entered here for the sample size.

### Control Limit Calculation Method

- None
- Exact Binomial or Poisson
- Normal Approximation of the Binomial or Poisson
- Average Moving Range of the plotted values
- Median Moving Range of the plotted values
- Standard Deviation of the plotted values
- Centerline only
- User defined limits

### Centerline Calculation Method

- Mean of the plotted values
- Median of the plotted values
- Known Parameter: Pi or Lambda
