# Calculation STATBEANS®

 

**STATBEAN Name:** ControlCharts

 

**Control Charts Software Purpose:** Calculates various types of [statistical control charts](https://www.statgraphics.com/statistical-process-control-charts) for both variables and attributes. In some cases, both a location control chart (such as an X-bar chart) and a dispersion control chart (such as an R chart) are created. In other cases, only a single chart is created (such as a P chart). Allows Statgraphics to function as control charts software.

**DataSource For Statistical Control Charts: **any.

controlCharts1.setChartType("X-bar and R"); 

//set the name of the column containing the data   
controlCharts1.setXVariableName("strength"); 

//set the subgroup size (if not 1)   
controlCharts1.setSubgroupSize(5); 

//set specification limits   
controlCharts1.setUpperSpecificationLimit(300.0);   
controlCharts1.setNominal(250.0);   
controlCharts1.setLowerSpecificationLimit(200.0); 

//create a table bean with 19 rows   
ControlChartsTable controlChartsTable1 = new STATBEANS.ControlChartsTable();   
controlChartsTable1.setNumberOfRowsInDisplay(19); 

//set the number of decimal places for displaying the limits   
controlChartsTable1.setDecimalPlaces(2); 

//create 2 plot beans   
ControlChartsPlot controlChartsPlot1 = new STATBEANS.ControlChartsPlot();   
ControlChartsPlot controlChartsPlot2 = new STATBEANS.ControlChartsPlot(); 

//turn off the legends   
controlChartsPlot1.setDisplayLimitValues(false);   
controlChartsPlot2.setDisplayLimitValues(false); 

//set the chart numbers for each plot   
controlChartsPlot1.setChartNumber(0);   
controlChartsPlot2.setChartNumber(1); 

//ask for warning limits on the first chart   
controlChartsPlot1.setShowOuterWarningLimits(true);   
controlChartsPlot1.setShowInnerWarningLimits(true); 

//add a smoother to the second chart   
controlChartsPlot2.setSmootherType("EWMA"); 

//make the calculation bean a listener for changes in the FileDataSource bean   
fileDataSource1.addDataChangeListener(controlCharts1.listenerForDataChange); 

//make the table and plot beans listeners for changes in the calculation bean   
controlCharts1.addDataChangeListener(controlChartsTable1.listenerForDataChange);   
controlCharts1.addDataChangeListener(controlChartsPlot1.listenerForDataChange);
