Scatter with Uneven X Error Bars

This tutorial will show how to use the TechGraph Editor to display uneven X error bars on a scatter graph.  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 Scatter.
  • X Data Type is Number. Numeric values for the X Axis are entered in X Data column.
  • Graph A contains the mean values.
  • Graph B contains the corresponding “left” X error values for Graph A.
  • Graph C contains the same mean values as Graph A.
  • Graph D contains the corresponding “right” X error values for Graph A.

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, X Axis, Y Axis, Curves and Error Bars) to change the settings and appearance of the chart.      

     Settings  – specify the color of line and markers for Graph A and C.     

  • Click on the “DarkGreen circle” (Graph Style) for Graph A to show the scatter Style for Graph A pop-up.  You can change the Color, Type and Size for Scatter A.    Click on Apply to save the changes.  Repeat this step for Graph C.  For this example, the marker style for Graph C should be identical to Graph A.

    X axis

  • Enter values in Minimum, Maximum and Major Div to set the X Axis scale and divisions. Leave these values empty for automatic scaling.

     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.

     Curves & Error Bars       

  • Select “Error Bar On” from Error Bar list for Graph A and Graph C.
  • Click on “Left Only” (Error Bar Format) for Graph B. For this example, “Up Only“ is selected from the Error Format list.  Color (“Crimson”) is selected for the error bar color.   Use the Thickness selection list to change the line style. Click on Apply to save the changes.  Repeat this step for Graph D.  “Right Only” error format is selected for Graph D.

      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.
