Visualizing data as a combination of charts and graphs


As a tenant administrator, editor, or viewer, you can use the BMC Combination Chart visualization to configure dashboards. This visualization combines charts and graphs to show the relationship between two or more metrics. You can use this visualization to fetch data from multiple sources in a single dashboard, such as: 

  • BMC Helix AIOps
  • BMC Helix Operations Management
  • BMC Helix Log Analytics
  • BMC Helix Cloud Security
  • BMC Helix Automation Console


The following use cases illustrate how you might configure dashboards with the BMC Combination Chart visualization in your production environment.

Example 1: Combination of line charts

Let's say you are a tenant administrator who wants to view the average CPU utilization (in left Y-axis) for multiple CPUs for a given period (in X-axis) in a single dashboard panel. You use the BMC Combination Chart visualization configured with a Metric query to create a dashboard to show the data in line chart format.


Example 2: Combination of bar charts

Let's say you are a tenant administrator who wants to view the average CPU and memory utilization (in left Y-axis) of two hosts (in X-axis) in a single dashboard panel. You use the BMC Combination Chart visualization configured with a Metric query to create a dashboard to show the data in bar chart format.


Example 3: Combination of line and bar charts

Let's say you are a tenant administrator who wants to view the average CPU utilization (in left Y-axis) and memory utilization (in right Y-axis) for a given period (in X-axis) in a single dashboard panel. You use the BMC Combination Chart visualization configured with a Metric query to create a dashboard to show the data in a combination of chart and graph format.

To create a dashboard with the data as shown in example 3:


  1. From the navigation menu , click Dashboard.
  2. Click Add visualization.
  3. In the Query section, select BMC Helix and add your queries; see Configuring dashboards, panels, and queries.
  4. In the Panel tab, expand Visualization and select BMC Combination Chart.



  5. Expand Display to configure the following elements:

    • Select a metric—Select a metric in this field. In example 3, Time metric has been used in the X-axis. 
    • Specify a label—Specify the label for this axis.
    • Show the axis—Click to show or hide the axis.
    • Select a metric—Select a metric from the list of available metrics. In example 3, Processor Utilization metric has been set for the left Y-axis and Memory Utilization metric has been set for the right Y-axis.
    • Select the chart type—Select BAR or LINE as the chart type. Example 3 shows the LINE chart type for the left Y-axis and BAR chart type for the right Y-axis.
    • Specify a label—Specify the label for the axis. Example 3 shows CPU Utilization as the label name for the left Y-axis and Memory Usage as the label name for the right Y-axis.
    • Show the axis—Click to show or hide the axis.
    • Decimals—Specify the decimals. In example 3, decimals has been set to 2 for both the Y-axes.

    • Min—Specify the minimum value for the Y-axes.

    • Max—Specify the maximum value for the Y-axes.

      Important

      You do not have to configure both Y-axes for your dashboard. You can configure any one of the Y-axes that suits your requirement.

    • Show Legends—Click to show or hide legends.
    • Legend Position and Legend Alignment—Select a legend position and alignment. These options are available only if you choose to show legends. In example 3, legend position has been set to Top and legend alignment has been set to Center.
    • Show Data Labels—Click to show or hide data labels.
    • Data Label Alignment and Data Label Decimals—Select a label alignment and decimal. These options are available only if you choose to show data labels. In example 3, data label alignment has been set to Center and data label decimals has been set to 2.
    • Orientation—Select horizontal or vertical orientation for your combination chart. The chart orientation has been set to Vertical in example 3.
    • Mode—Select a separated or stacked combination chart for multiple value bars. In a stacked combination chart, each series is stacked on top of another. In example 3, the Stacked mode has been selected.
    • Null behavior—Display the null values in the combination chart by selecting Break or Zero. The recommended value for this parameter is Zero. The null behavior has been set to Zero in example 3.
    • Bar width, Line width and Color Scheme—Configure the values as you want to see them in the combination chart.
    • Show Cumulative TotalEnable this option to display the cumulative values of previous data points on the left or right Y-axis. This option is only available in LINE charts.
    • Customize Chart Type By MetricThis option allows you to select different chart types for various metrics in charts.
  6. Save the panel.
