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 Zoomdata data connectors except Cloudera Search. They are supported by Zoomdata Apache Solr connectors for version 5.2 or later.
To configure the default settings for multiple metric line charts for a data source configuration:
Edit the appropriate data source configuration. See Editing a Data Source Configuration.
Select the Charts tab in the data source configuration wizard.
On the Standard subtab of the Charts 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 chart.
In the second (rightmost) box for this setting, specify the date and time granularity used to group the data. Valid granularities are Millisecond, Second, Minute, Hour, Day, Week, Month or Year.
If some of these granularity options do not appear, verify that the granularity specified for this field on the Fields tab is set at the correct granularity level.For each field, the available granularity options include all options starting from Year down to the granularity level specified for this field on the Fields tab.
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 chart 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 chart. 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 Available Metric Functions. Display Legend Select this checkbox to enable the color legend. Also identify the legend type and the color palette or range.
