...remove/ignore an outlier or other data

See also ...highlight an outlier

One task SigmaPlot does not do easily is to omit or ignore an outlying point or group of points. There are several means to accomplish this manually. One option is to simply convert the number to a text cell, thereby removing the data point from both graphing and computation.

1. Find the outlier on the graph, then click it to select the curve. Now, click it again (this is not a double-click; be sure to pause before the second click.
    
2. View the worksheet. The data for the selected symbol should be indicated with colored highlighting.
   
   
   
3. Select the highlighted worksheet cell(s), then choose the Format menu Cells command. Select the Type of cell to be Text, then click OK. This converts the number to text characters; you can tell this if the alignment of the cell changes to be left aligned.
   
   
   
4. Now, the data point is no longer plotted, and if you perform additional statistics on the graph, the data point will also be ignored.
