You create a scatterplot of Yield vs. Input, and notice three points that seem to be outliers. You can brush these points to identify the worksheet rows that contain the data for these points.
When you are in brushing mode, the Brushing palette appears. The Brushing palette lists the worksheet row numbers that contain the brushed points, so that you can find them in the worksheet. In the worksheet, the rows that correspond to the brushed points are identified by symbols beside the row numbers.
To exit brushing mode, choose.
When you brush points in one graph, Minitab automatically brushes points from the same row in all other graphs that are in brushing mode. This is true whether the graphs are in the same Graph window or in other Graph windows. Brushing across graphs can help you investigate relationships across many variables.
To view more information about the brushed points, you can add variables from the worksheet to the Brushing palette. These variables are called ID variables.
To display ID variables in the palette, first brush the points on the graph. With the graph active, choose Variables, enter the variables that you want to appear in the Brushing palette.. In
You can create a column in the worksheet to use as an indicator variable that identifies brushed rows with a value of 1 and unbrushed rows with a value of 0 (by default). You can use the indicator variable as a grouping variable for other operations or analyses, such as subsetting worksheets and regression analysis.
To add indicator variables to the worksheet, first brush points on the graph. With the graph active, choose Column, enter a name or column number for the indicator variable column.. In
For most graphs on the Graph menu, you can create another graph either by including only brushed points or by excluding all brushed points.
First, brush the points that you want to include or exclude from the new graph. Choose the graph or control chart that you want to create. Click Data Options. On the Subset tab, under Include or Exclude, specify whether you want to include or exclude the brushed rows. Under Specify which rows to include, choose Brushed rows.
Brushing is not available for graphs in which points represent more than one worksheet row. For example, if data for all subgroups are in one column and each point on a control chart represents the mean of a subgroup, brushing is not available.
