Box Plot with Median and Whiskers

This tutorial will show how to use the box-whisker graph in TechGraph Editor to calculate median and whiskers values from a column of sample data. Shown below are the settings in the Data Table and the Edit Chart used to create this chart.      

Data Table – Sample data can easily be changed or replaced by pasting data from an external worksheet.
  • Graph Type is Box-Whisker.
  • X Data Type is Label.  Data in X Column entries are ignored.
  • Graph A contains data for “Control”.
  • Graph B contains data for “1 hour”.
  • Graph C contains data for “10 hours”.
  • Graph D contains data for “24 hours”.

Note:   Click on the “Help” button on the toolbar to find out how to edit, delete, copy and paste in the Data Table.

Edit Chart – A set of icons (Titles, Settings, Y Axis, Box-Whisker ) to change the settings and appearance of the chart.      

     Settings  – specify the style of the whisker box for Graph A, B, C and D.

  • Enter legend entry for Graph A, B, C and D. The legend text is used as labels for the X Axis.  For this example, “Control” is legend text for A, “1 hour” for B, “10 hours” for C and “24 hours” for D.
  • Select “None” for Legend Placement. The legend text for Graph A, B, C and D are placed below the X Axis.
  • Click on the Graph Stylefor Graph A to show the Style for Graph A pop-up.  Use the Color, Fill, Pattern and Thickness to set the whisker box style   Click on Apply to save the changes.  Repeat this step for Graph B, C and D.

     Y axis

  • Enter values in Minimum, Maximum and Major Div to set the Y Axis scale and divisions. Leave these values empty for automatic scaling.
    • The values for this example are Minimum= 0, Maximum =120 and Major Div = 6.

     Box-Whisker

  • Check Box checkbox to display the whisker box for each column.
  • Check Median and Whisker checkboxes. Median, upper and lower whisker values are calculated from the column sample data.

     Edit Chart Toolbar Options
