Line Trend: Multiple Metric Charts
Multiple metric line charts are based on multiple metrics and one time attribute. Multiple metric line charts are supported by all Composer data connectors except Cloudera Search. They are supported by Composer Apache Solr connectors for version 5.2 or later.

Configure Default Multiple Metric Line Chart Settings for a Data Source
To configure the default settings for multiple metric line charts for a data source configuration:
Edit the appropriate data source configuration. See Edit a Data Source Configuration.
Select the Visuals tab in the data source configuration wizard.
On the Standard subtab of the Visuals tab, select Line Trend: Multiple Metrics.
If you want to be able to display the data collected by this data source configuration as a multiple metric line chart, make sure the Line Trend: Multiple Metrics checkbox is selected.
Default multiple metric line chart settings appear on the right side of the page.
Configure the default settings as follows:
Setting Description Trend Attribute Select the time trend attribute for the visual.
In the second (rightmost) box for this setting, specify the date and time granularity used to group the data.
Valid granularity options are Millisecond, Second, Minute, Hour, Day, Week, Month, Quarter, or Year. If some of these granularity options do not appear, verify that the granularity specified for this field on the Fields tab of the data source definition is set at the correct granularity level.
The refinement level of the field data in a data store defines the minimum level of granularity that should be set for the field. Specifying granularity for a field that is lower than the refinement level of the field data will not produce a visual with data grouped at the requested lower level. For example, if a field's data is stored in hours, requesting the granularity of that data lower than hours will produce the values up to the hour level, and the more detailed level information will be zeros (i.e., 0 minutes, 0 seconds, and 0 milliseconds).
Trend Attribute Limit Specify the number of time attribute items. Trend Attribute Sort Shows the time parameter by which the trend attributes will be sorted. You can select the sorting order (Chronological or Reverse Chronological). Y Axis Select the metrics you want displayed on your visual. You can also define the default aggregation function used for the metric values: SUM, AVG, MAX, MIN, or (for some data sources) LAST VALUE. See Metric Aggregation Functions. Select
.
Configure Settings for a Specific Multiple Metric Line Chart
To change the settings for a specific multiple metric line chart:
Edit the multiple metric line chart you want to modify. See Edit Visuals.
If you are editing the visual in a dashboard, select Edit Visual from the visual drop-down menu. The sidebar menu for the visual appears.
If you are editing the visual from the Visual Gallery, the sidebar appears to the right of the visual.
Select
on the sidebar menu. The Line Chart Settings sidebar for the visual appears.
Alter the settings as needed:
Setting Description Display Style Select Line Chart or Area Chart to indicate the type of chart you want to see. Line Chart is selected by default. The Area Chart setting turns on the fill option for the line chart (fills the visual with appropriate colors between the lines). The Line Chart setting turns off the fill option (so only lines appear). Line Thickness Increase or decrease the thickness of the lines in the visual using the up and down arrows in this box. Select
to save the dashboard and the visual with its updated settings.
Configure Colors for a Specific Multiple Metric Line Chart
To specify the color settings for a specific multiple metric line chart using the Color sidebar:
Edit the visual you want to modify. See Edit Visuals.
If you are editing the visual in a dashboard, select Edit Visual from the visual drop-down menu. The sidebar menu for the visual appears. If you are editing the visual from the Visual Gallery, the sidebar appears to the right of the visual.
Select
on the sidebar menu. The Color sidebar for the visual appears.
Configure the color settings as described below. As you change the color settings, the legend at the top of the Color sidebar shows how the legend will appear on the visual. Supported color specifications are described in Specify Colors.
Setting Description Legend Slide the bar to the right if you want the legend to be displayed on the visual or to the left to hide the legend. Color Manually select the color for each metric using the color selector.
<type> Color Palette If a color palette is specified for this visual type in the data source defaults, select the color palette for this specific visual. If a color range is selected for visuals in the data source defaults, this setting is not available. (The actual title of this setting varies by the visual type you have selected.) Select the Inherit from theme checkbox to use the color palette specified by the theme. Close the Color sidebar and the color settings are dynamically applied to the visual.
Select
to save the dashboard and the visual with its updated settings.
