A scatter chart shows the relationship between two values (dimensions or measures). Their values are represented as points. A scatter chart always has two axes: the values of one dimension or measure are plotted along the X-axis and those of the other along the Y-axis. A data point that links these two values is displayed at the intersection of the X and Y coordinates. These data points can be distributed along the X-axis evenly or unevenly, depending on specific data.
Use this type of chart if you need to find the dependency between dimensions and measures or show a range of values. For example, the relationship between the average order value and the number of orders for a product.
You can also represent dependencies on a scatter chart using point sizes. The size of a point depends on the measure value: the higher the value, the larger the point size. For example, the size of a point may depend on the discount on a product.
Dimension. Specifies the number of points on the chart.
Measure. Sets a point size depending on the measure value.
Dimension or measure. Affects the color of points.
Dimension. Can only use a dimension from the X axis. Affects the sorting of the X axis. The sorting direction is marked with an icon next to the field:
descending. To change the sorting direction, click the icon.
If the source data includes a row where the measure value is null, the chart will not be built for that point at default settings. For example, if the source has a row with a date (20.07.2022) but the sales amount for it is missing.
You can configure how the chart will display null values in the chart section settings:
In the section with a measure whose values you want to show, in the top-right corner, click
(the icon appears when you hover over the section).
In Empty values (null), select Display as 0.
Now, the chart will use 0 instead of null.
If a row is missing from the source data completely, the chart section settings will not change the way the chart is presented. For example, if the source does not have a row with a certain date (20.07.2022), nothing will be shown for this date on the chart.
If the values of the categories contain a large amount of text, try to reduce it. Then the signatures on the diagram will look more accurate. You can use string functions in the calculated fields or conditional operators CASE.
The axis scale often varies and may start with a value other than 0. Pay attention to value signatures.
A scatter chart isn't suitable for visualization of data over time.
When visualizing multiple measures, select colors carefully. They should be distinguishable and contrasting.
