Dashboard visualization types

This article outlines the types of visualizations available to use in AI/BI dashboards and shows you how to create an example of each visualization type. For instructions on building a dashboard, see Create a dashboard.

Note

To optimize performance, charts can only render 10K rows or 10MB on the canvas, whichever is smaller. Otherwise, visualizations can be truncated.

Area visualization

Area visualizations combine the line and bar visualizations to show how one or more groups’ numeric values change over the progression of a second variable, typically that of time. They are often used to show sales funnel changes through time.

Configuration values: For this area visualization example, the following values were set:

• Dataset: TPCH orders

• Visualization: Area

• Title: Total price and order year by order priority and clerk

• X-axis:

  • Field: o_orderdate

  • Scale Type: Temporal

  • Transform: Yearly

  • Axis title: Order year

• Y-axis:

  • Field: o_totalprice

  • Axis title: Total price

  • Scale Type: Quantitative

  • Transform: Sum

• Group by:

  • Field: o_orderpriority

  • Legend title: Order priority

• Filter

  • Field: TPCH orders.o_clerk

SQL query: For this area visualization, the following SQL query was used to generate the data set named TPCH orders.

SELECT * FROM samples.tpch.orders

Box chart

The box chart visualization shows the distribution summary of numerical data, optionally grouped by category. Using a box chart visualization, you can quickly compare the value ranges across categories and visualize the locality, spread, and skewness groups of the values through their quartiles. In each box, the darker line shows the interquartile range. For more information about interpreting box plot visualizations, see the Box chart article on Wikipedia.

Configuration values: For this box chart visualization, the following values were set:

• X column (dataset column): l-returnflag

• Y columns (dataset column): l_extendedprice

• X axis name (override default value): Return flag1

• Y axis name (override default value): Extended price

SQL query: For this box chart visualization, the following SQL query was used to generate the data set.

select * from samples.tpch.lineitem

Bubble chart

Bubble charts are scatter charts where the size of each point marker reflects a relevant metric. To make a bubble chart, select Scatter as your visualization type. In the Size setting, select the metric you want represented by the size of the markers.

Histogram chart

A histogram plots the frequency that a given value occurs in a dataset. A histogram helps you to understand whether a dataset has values that are clustered around a small number of ranges or are more spread out. A histogram is displayed as a bar chart in which you control the number of distinct bars (also called bins).

Configuration values: For this histogram chart visualization, the following values were set:

• Dataset: TPCH orders

SELECT * FROM samples.tpch.lineitem

Point map

Point maps display quantitative data as symbols placed at specific map locations. Markers are positioned using latitude and longitude coordinates, which must be included as part of the result set for this chart type. The following example uses data from motor vehicle collisions in New York, NY.

Configuration values: For this point map visualization, the following values were set:

• Dataset: motor vehicle collisions

• Visualization: Symbol map

• Coordinates:

  • Latitude: LATITUDE

Number formatting in charts

For most chart types, you can format numeric values for axis tick labels, data labels, and tooltips. To choose a formatting style, click the kebab menu to the right of the X Axis or Y Axis label in the chart configuration panel. Then, click Format to show formatting options.

The following charts support number formatting:

• Area

• Bar

• Combo

• Counter

• Heatmap

• Histogram

• Line

• Pivot

• Scatter

• Table (Legacy formatting)

You can choose from the following formatting options:

• Type: None, Currency ($), Percentage (%)

• Abbreviation: None, Compact, Scientific

• Decimal places: Max, Exact, All, Number of places Optionally, you can include a group separator such as a comma.

Note

Formatting is available for various types of currency. After selecting Currency as the Type, use the drop-down selector to choose your preferred currency.
