Bubble Graph

Intro

Similar to Scatter Plot graphs, Bubble graphs have two value scales, and x and y coordinate pairs are plotted on the graph. Bubble graphs are more complex than Scatter Plot graphs in that they include an additional dimension—bubble size. The size of any bubble on the graph is relative to the size of the other bubbles in the graph. For example, if your graph contained two series, one with a size value of 25 and the other with a size value of 50, the bubble with a value of 50 would appear twice the size of the smaller bubble in the graph.

You can also apply timeline data instead of value data to the x-axis. In this case, all bubbles are plotted on their appropriate date/time lines. The position of a bubble on a given line is still determined by its y coordinate value, however.

Powering Bubble graphs

A Bubble graph requires three columns or rows of data from your DataSet:

  • A column or row containing values to be measured on the y-axis.

  • A column or row containing values or date-time data to be measured on the x-axis

  • A column or row containing size values for each bubble.

You can also add an optional series column if you want. If you do not include a series column, no legend appears. Prior to our August 2017 release, series data was required, but this is no longer the case. You can still use the old version of the chart by selecting the Bubble (Legacy) chart type.

Note: When you drill down into a Bubble chart, you can drill into the series data only, not the x- or y-axis data. For more information about drilling into data, see Drilling into Data.

For information about value, category, and series data, see Understanding Chart Data.

In the Analyzer, you can choose the columns containing the data for your Bubble graph. For more information about choosing data columns, see Applying DataSet Columns to Your Chart.

For more information about formatting charts in the Analyzer, see KPI Card Building Part 2: The Analyzer.

Customizing Bubble graphs

You can customize the appearance of a Bubble graph by editing its chart properties. For information about all chart properties, see Chart Properties. Unique properties of Bubble graphs include the following. You can click a thumbnail image to see a larger image.

Property 

Description

Example

Grid Lines > Hide All Grids

Turns off grid lines. This is useful when you want to create a "quadrant chart" (that is, a chart divided into four sections using two coordinate lines).

Grid Lines > Y Zero Line Color

Determines the color of the horizontal "zero line" in Bubble and Scatter Plot graphs. This attribute does not work if the zero line is also the baseline in the graph (that is, the chart must contain negative values). In the example, this property has been set to red.

Grid Lines > Y Zero Line Width

Determines the width of the horizontal "zero line" in Bubble and Scatter Plot graphs. This attribute does not work if the zero line is also the baseline in the graph (that is, the chart must contain negative values). In the example, this property has been set to 5.

Grid Lines > X Zero Line Color

Determines the color for the vertical "zero line" in Bubble and Scatter Plot graphs. This attribute does not work if the vertical zero line is the leftmost line in the graph (that is, the chart must contain negative values). In the example, this property has been set to red.

Grid Lines > X Zero Line Width

Determines the width of the vertical "zero line" in Bubble and Scatter Plot graphs. This attribute does not work if the zero line is the leftmost line in the graph (that is, the chart must contain negative values). In the example, this property has been set to 5.

Quadrant Lines > X Scale Value

Allows you to set the value for the vertical quadrant line when creating a "quadrant chart." If you do not specify a value for this property, no vertical quadrant line appears.

The example shows a Bubble graph in which both the X and Y scale quadrant lines have been set to the midpoint value of 50. This dissects the graph into four quadrants of equal area.

Quadrant Lines > Y Scale Value

Allows you to set the value for the horizontal quadrant line when creating a "quadrant chart." If you do not specify a value for this property, no horizontal quadrant line appears.

Regression Lines > Show Linear Regression Lines

Allows you to add a regression line for each series in a Scatter Plot or Bubble chart.
