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 Primary value list, select the parameter to use for the primary data line in a line chart with reference lines or a primary tick mark in a KPI gauge.
From the Secondary value list, select the parameter to use for the secondary data line in a line chart or a secondary tick mark in a KPI gauge. If you do not want to specify a secondary value, select (none).
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).
Select Hide axis tick labels if you want to hide the axis tick labels when a user zooms out the view of an indicator. When the user zooms in, the axis tick labels reappear. Select this setting to avoid visual clutter when the view is zoomed out.
Select Hide axes when zoomed out if you want to hide the axes when a user zooms out the view of an indicator. When the user zooms in, the axes reappear. Select this setting to avoid visual clutter when the view is zoomed out.
Click Hide reference lines if you want to hide the reference lines when a user zooms out the view of an indicator. When the user zooms in, the reference lines reappear. Select this setting to avoid visual clutter when the view is zoomed out.
