Bubble

Use the Bubble chart when you want to show magnitude.

A bubble chart shows three dimensions of data.

Each bubble represents a data point with 3 variables. Variable 1 and variable 2 determines the bubble's location on the horizontal and vertical axis. Variable 3 determines the bubble's size.

A bubble chart is similar to a scatter plot where a third variable is added to determine the size of the bubbles.

Input

The Bubble chart can use both text and numeric input.

Configuration

Use the following configuration options to configure the Bubble chart.

Note

The Configuring the Bubble chart gives configuration options through the Pipe module. If you have charts already created, you can access them through your Dashboards.

Configuring the Bubble chart

  1. Go to the Pipes module from the side navigation bar.

  2. From the Pipes tab, click an existing pipe to open, or create a new pipe. To create a new pipe, read the Creating a pipe documentation.

  3. In the Pipe builder, add a data source to your pipe. For more information on adding a data source, see the Data Input tool.Data Input

  4. Add tools to build out your pipe. For more information about adding tools to your pipe, see the Using the Pipe builder canvas documentation.

  5. Create a chart from your pipe by clicking Charts on the canvas toolbar.

  6. Click Create Chart.

    The chart page opens.

  7. From the configuration pane, go to the Setup tab, and select the tool that you want to create a chart for.

    Note

    Whatever tool you select in your pipe when you add the chart is selected by default.

  8. Under Chart type, start typing Bubble to filter the list, then click the Bubble graphic to select it.

  9. Under the X axis, select a column. The X axis populates the data along the chart's horizontal axis.

  10. Under Y axis, select a numeric column. The Y axis populates the data along the chart's vertical axis.

  11. Under Series, select the text or numeric column to use for the chart.

  12. Expand the Advanced field, click Show to select either Preview or Last built:

    • Preview displays the first 100 rows of your data from your last build.

    • Last build displays the first 1000 rows of your entire dataset from your last build.

  13. Under Size, select the numeric column to use.

  14. Under Sort, select to sort your chart data by None, Ascending or Descending.

  15. Click the Customize tab to add custom styling to your chart.

    1. Under Chart and axis titles, select the following to add titles to your charts. To update the title from "Untitled" to something meaningful, click on the title to edit.

      • Include the chart title

      • Include chart subtitle

      • Include the horizontal axis title

    2. Under Horizontal axis label angle, select the degree from the drop-down list of angles for the horizontal axis label. This option is useful if you have longer labels, as angling the text can free up more space in your chart.

    3. Click the Include vertical axis title checkbox to add the vertical axis title.

    4. Under Vertical axis label angle, select the degree from the drop-down list of angles for the vertical axis label.

    5. Under Left margin, enter the padding for the left margin or click the arrows to increase or decrease the number.
