Scatter chart in DataLens On-premises

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.

  Example

  For example, the size of a point may depend on the discount on a product.

  Product	Category	Average order value	Number of orders	Discount
  Floor cleaner liquid	Household cleaners	153.0	1	0
  Multicooker with 40 modes	Home appliances	3442.0	1	0
  Liquid detergent for colored clothes	Household cleaners	525.0	1	0
  Carpet detergent	Household cleaners	463.0	1	0
  Lemon dishwashing liquid	Household cleaners	362.0	1	0

• You can use a gradient in a chart by adding a measure to the Color section. For example, the higher the product's average check, the darker the point.

Creating a scatter chartCreating a scatter chart

To create a scatter chart:

1. Go to the DataLens home page.

2. In the left-hand panel, select Charts.

3. Click Create chart → Chart.

4. At the top left, click Select dataset and specify the dataset to visualize. If you do not have a dataset, create one.

5. Select Scatter chart as the chart type.
6. Drag a dimension from the dataset to the X section.
7. Drag one or more measures from the dataset to the Y section. The values will be displayed as points at the intersection of the X and Y axes.

Additional optionsAdditional options

Also, you can:

• Change the color of points:

  1. Drag a dimension or measure to the Colors section.
  2. Click and set new colors.

• Resize points:

  1. Drag the measure to the Point size section.
  2. Click and set the minimum and maximum point sizes for the specified measure.

  Note

  A scatter chart isn't suitable for visualization of data over time.

• Specify an additional dimension. To do this, drag a dimension to the Points section.

Configuring display of null valuesConfiguring display of null values

• If the source data has a row with null for a measure value, this point will not be plotted on a chart with default settings.

  For example, if the source has a row with the date, 20.07.2022, but the sales total for it is not specified.

  To set up null value display on a chart:

  1. Click in the top-right corner of the section with the measure you want to configure (the icon appears when you hover over the section).
  2. In Empty values (null), select Display as 0.
  3. Click Apply. Now the chart will use 0 instead of null.

• If a row is missing from the source data altogether, the chart section settings will not change the chart.

  For example, if the source does not have a row with the particular date, 20.07.2022, nothing will be shown for this date on the chart.

RecommendationsRecommendations

• Labels. If the category values are too verbose, make them shorter so that the chart labels look neater.

  You can use string functions in calculated fields or the CASE conditional statements.

• The axis scale often varies and may start with a value other than 0. Pay attention to value signatures.
• Colors. When visualizing multiple measures, select colors carefully. They should be distinguishable and contrasting.
