Y-axis title	Set to Weight in Pounds
Scale X axis	This setting is selected.
Scale Y axis	This setting is selected.

You can customize the following display settings for this indicator:

(Required) From the X-axis value list, select the column in your data that you want to use for the X-axis value in the indicator. When you view your indicator data, the columns in the data set are described by the values in the Column Name column. The selections available in the X-axis value list are all of the values in the Column Name column.
(Required) From the Y-axis value list, select the column in your data that you want to use for the Y-axis value in the indicator. When you view your indicator data, the columns in the data set are described by the values in the Column Name column. The selections available in the Y-axis value list are all of the values in the Column Name column.
In the X-axis title field, type the title to use for the X axis in the indicator. If you do not specify a title, the value that you selected from the X-axis value list is used by default. If you do not want a title, type a space in the field. If you select Scale X axis, a measurement label is added to the title.
In the Y-axis title field, type the title to use for the Y axis in the indicator. If you do not specify a title, the value that you selected from the Y-axis value list is used by default. If you do not want a title, type a space in the field. If you select Scale Y axis, a measurement label is added to the title.
Select Scale X axis if you want to scale that axis. When you make this selection, a measurement label is added to the X-axis title if the data is numeric. For example, if the X-axis title is set to Revenue and you select Scale X axis, the X-axis title is displayed as Revenue (millions).
Select Scale Y axis if you want to scale that axis. When you make this selection, a measurement label is added to the Y-axis title if the data is numeric. For example, if the Y-axis title is set to Revenue and you select Scale Y axis, the Y-axis title is displayed as Revenue (millions).

Sample Data Structure

To create a scatter histogram, you must provide two measures (X-axis value and Y-axis value).

Tip
