Given an array of control chart points and the control chart lines cluster as created by the chart VIs Draw Control Chart creates a control chart (X-Y graph indicator) with points plotted against upper and lower control limits and center lines. The SPC Custom Control named Basic Control Chart and Control Chart Lines cluster are formatted to connect to the outputs of this VI.

Inputs/Outputs

  • c1ddbl.png points —

    points are the points to be plotted on the control chart, normally the output of one of the control chart VIs, such as an X-bar array.

  • cnclst.png chart limits —

    chart limits is output by the control chart VIs.

  • cdbl.png avg UCL —

    chart limits is output by the control chart VIs.

  • cdbl.png CL —

    chart limits is output by the control chart VIs.

  • cdbl.png avg LCL —

    chart limits is output by the control chart VIs.

  • cdbl.png standard error —

    chart limits is output by the control chart VIs.

  • ci32.png starting sample number (0) —

    (I32, default = 0) - the sample number of the first sample used to label the chart x-axis. If left unconnected, sample labeling on the x-axis will start at 0.

  • i1dcclst.png control chart —

    (X, Y Graph) - a control chart graph with points and limit lines drawn.

  • inclst.png control chart lines —

    cluster of (useful as a legend): UCL (DBL) - the upper control limit value for the control chart. CL (DBL) - the center line value for the control chart. LCL (DBL) - the lower control limit value for the control chart.

  • idbl.png UCL —

    (DBL) - the upper control limit value for the control chart.

  • idbl.png CL —

    (DBL) - the center line value for the control chart.

  • idbl.png LCL —

    (DBL) - the lower control limit value for the control chart.

    • Draw Control Chart Details

    This VI produces control charts with control limit lines. The control limit lines in the control chart shift if the standard error multiplier changes. To view the change in zone lines by altering the standard error, use the Draw Chart with Zones VI to create a control chart.
