Box Plot with Mean and Standard Dev.

This tutorial will show how to use the box-whisker graph in TechGraph Editor to calculate mean and SD(Standard Deviation) 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 markers 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 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 error bar style.  Use the Color, Type and Size for markers.   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 Sample Data checkbox to display the sample data for each column.
  • Check Mean and Standard Dev. checkbox. Mean and SD values are calculated from the column sample data.

     Edit Chart Toolbar Options

  • Print Chart prints your chart.
  • Download Image downloads your chart as an SVG(Scalable Vector Graphics) file or image file(PNG, JPEG, TIF, PDF).
  • Drawing Objects customize your chart with labels, lines, arrows, circles, images, and logos.
