ChartType property

Use the ChartType property to specify the type of chart for plotting the data points or set the chart type to Default to use the chart configured in MES database for the characteristic or the characteristic/QM Specification link if the characteristic setting has been overridden. You can set the chart type to a valid value that is listed along with the ChartType enumeration.

For variable sample sizes, you can use the following chart types:

• XBarR (Mean and Range, 2)

• XBarSigma (Mean and Sigma, 3)

• IxIr (Individual X and Moving Range, 5)

• MARange (Moving Average and Range, 7)

• MASigma (Moving Average and Sigma, 8)

For binary attribute characteristics, you can use the following chart types:

• PercentDefective (p, 16)

• NumberDefective (np, 17)

For counted attribute characteristics, you can use the following chart types:

• NumberofDefectives (c, 19)

• DefectsperUnit (u, 18)

• DefectsperMillionOpportunities (DPMO, 20)

The following figure highlights the selected chart type as shown in the chart header area.

You must ensure that the values assigned to chart types match the values in the default_chart column of the characteristic table. The Default chart type is assigned a value of 0. This is a design-time and a run-time property.

Example code for setting this property is:

SpcChartControl1.ChartType = FactMES.Controls.ChartType.PercentDefective;

You cannot set this property to Null.
