Convert Fields between Discrete and Continuous
You can convert measures from discrete to continuous or from continuous to discrete. And you can convert date dimensions and other numeric dimensions to be either discrete or continuous. For more information on continuous and discrete fields, see Dimensions and Measures, Blue and Green(Link opens in a new window).
You can also Convert a Measure to a Dimension.
Convert measures
You can convert measures from discrete to continuous or from continuous to discrete. Click the field and choose Discrete or Continuous. The field is green when it is continuous, and blue when it is discrete.
For measures in the Data pane, right-click the field and choose Convert to Discrete or Convert to Continuous. The colour of the field changes accordingly.
Convert date fields
You can convert Date fields between discrete and continuous. Discrete dates act as labels and continuous dates will have an axis similar to a measure.
Click any Date field in the view and choose one of the options on the context menu to change it from discrete to continuous or from continuous to discrete.
To convert a Date field in the Data pane (and thus to determine the default result when you drag it into a view), right-click the field and choose Convert to Discrete or Convert to Continuous.
