Given an array of control chart points, arrays for the upper and lower control limits, and the control chart lines cluster as created by the chart VIs, Draw Chart with Var Limits creates a variable limits control chart (X-Y graph indicator). Use this with the u Chart and p Chart if you have a variable subgroup size. The SPC Custom Controls named Control Chart with Var Limits 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.

  • c1ddbl.png UCL —

  • c1ddbl.png LCL —

  • 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 with var limits —

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

  • inclst.png control chart lines —

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

  • idbl.png UCL —

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