To add error bars or highlighting to a Scatter Plot, these values must be entered into columns in the Spreadsheet.  

 

To define values for the Error Bars,

1.Go to an empty column of the Spreadsheet

2.Enter the value of the error for each row (each row corresponds to an individual bar).  This value may be freetext or a custom token.  

3.Choose the appropriate Spreadsheet column for the Error Bar Param. drop-down (see above).

 

An example of a Scatter Plot with Error Bars and its associated Spreadsheet is shown in the figure below.

 

To define a Highlighting rule,

1.Go to an empty column of the Spreadsheet

2.Enter the value of the rule for each row (each row corresponds to an individual point).  The rule must be a formula evaluating to "TRUE" or "FALSE";  if "TRUE," the point will be highlighted with the color defined in number2, number3, number4 and number5 above. An example of a Highlighting rule referring to a cell within the Spreadsheet is shown below in Figure 5.249.

3.Choose the appropriate Spreadsheet column for the Highlight Param. drop-down (see above).

 

An example of a Scatter Plot with Highlighting and its associated Spreadsheet is shown in the Figure below.
