Specification

Aggregation

XYZ Chart treats X value and Y value as dimensions and Z value as a metric, aggregating Z for each combination of X and Y. See Dimensions and metrics for the concepts behind dimensions and metrics.

Item	Role	Notes
X value	Dimension	Becomes the X axis.
Y value	Dimension	Becomes the Y axis.
Z value	Metric	Specified for bubble and heatmap.
Group by	Dimension	Scatter and bubble only (splits the series).

Examples

• Show "total sales by product category × region" as a heatmap.
  • X value: product category.
  • Y value: region.
  • Z value: sum of sales.
• Show "the relationship between ad spend and sales" as a bubble chart.
  • X value: ad spend.
  • Y value: sales.
  • Z value: profit.

X-axis specification

In XYZ Chart, how the X and Y axes are treated depends on the drawing type.

• For heatmap, both the X and Y axes are category axes.
• For scatter and bubble, the X axis is a category, time, or numeric axis depending on the data type, and the Y axis is a numeric axis.

For the behavior of each axis (display rules for category, time, and numeric axes), see X-axis specification for XY Chart.
