Candlestick chart reference

How to configure candlestick charts.

 Candlestick charts help you visualize ranges in your data, including opening and closing values, and the highs and lows of each range.

Candlestick charts in Looker Studio

Candlestick charts are typically used to represent financial patterns over short periods of time.

The box portion of the chart represents the opening and closing values of a period. The "wick" portions of the chart, which are the lines that extend vertically from the top and bottom of the box and end at the maximum and minimum values in your data, display the highest and lowest values during a period. 

if the closing value is lower than the opening value, the box will appear filled.

If the closing value is higher than the opening value, the box will appear hollow

 Candlestick chart example

The following candlestick chart displays the opening, closing, highs, and lows of monthly stock price trends for January, February, March, April, and May of 2022. 

The filled boxes indicate that the closing values for January, March, and April were lower than the opening values. The hollow boxes indicate that the closing values for February and May were higher than the opening values. 

 A candlestick chart displays monthly stock trends for January, February, March, April, and May of 2022.

You can hover your cursor over the columns in a candlestick chart to access a tooltip that displays more details about the data.

Requirements

Candlestick charts require four metrics: 

  • A high value — This value is represented as the highest point of the candle’s top wick.
  • An opening value — This value is represented as one border of the box.
  • A closing value — This value is represented as one border of the box.
  • A minimum value — This value is represented as the lowest point of the candle's bottom wick.
The metrics must be arranged in order of high valueopening value, closing value, and minimum value in the Metric section in the Setup tab in the Properties panel. 

Configure the chart

Add a new chart or select an existing chart. Then, on the right, use the Properties panel to configure the chart's Setup and Style tab properties.

Set up the chart data

 The options in the Setup tab determine how the chart's data is organized and displayed.

Data source

A data source provides the connection between the component and the underlying dataset. 

  • To change the chart's data source, click the current data source name.
  • To view or edit the data source, click Edit. (You must have at least Viewer permission to see this icon.)
  • Click +BLEND DATA to see data from multiple data sources in the same chart. Learn more about data blending.

Date range dimension

This option appears if your data source has a valid date dimension.

Note: This option does not appear for Google Ads or Google Analytics data sources, as these automatically select a dimension of type Date from the data source.

The Date range dimension is used as the basis for limiting the date range of the chart. For example, this is the dimension that is used if you set a date range property for the chart or if a viewer of the report uses a date range control to limit the time frame.

Dimension 

Dimensions are data categories. Dimension values (the data that is contained by the dimension) are names, descriptions, or other characteristics of a category.

At least one dimension is required. The first dimension that you specify serves as the primary data series in the chart. If you specify a breakdown dimension, the chart is limited to a single metric.

Drill down

Select the Drill down switch to turn on drilling for the chart, and select a drill down field from the Default drill down level drop-down menu.

Metric

Metrics measure the things that are contained in dimensions and provide the numeric scale and data series for the chart.

Metrics are aggregations that come from the underlying data set or that are the result of implicitly or explicitly applying an aggregation function, such as COUNT(), SUM(), or AVG(). The metric itself has no defined set of values, so you can’t group by a metric as you can with a dimension.

Learn more about aggregation.

Four metrics are required for a candlestick chart. See the Requirements section on this page for more details. 

Optional metrics

You can add optional metrics by selecting the Optional metrics switch and selecting metrics from the Add metric field selector. You can also drag and drop metrics from the fields list on the Data panel to the Optional metrics selector.

Metric sliders

Turn on the Metric sliders switch to add a metric slider to your candlestick chart.

Sort

Select a field that will sort your candlestick chart results. The default sort order will be by the first dimension, unless otherwise specified.

Select either the Ascending or the Descending option as desired.

Default date range

The Default date range property lets you set a timeframe for an individual chart.

Default date range options

Auto Uses the default date range, which is determined by the chart's data source.
Custom Lets you use the calendar widget to select a custom date range for the chart.
Date compare type Displays comparison data for the selected time period.

Learn more about working with dates and time. 

Filter

Filters restrict the data that is displayed in the component by including or excluding the values that you specify. Learn more about the filter property.

Filter options

Filter name Click an existing filter to edit it. Mouse over the filter name and click X to delete it.
+Add a filter Click this option to create a new filter for the chart.

 

Chart interactions

Use the Chart interactions section to turn on settings that let users interact with charts. The settings include the following: 

  • Cross-filtering — Lets you interact with one chart and apply that interaction as a filter to other charts in the report. When cross-filtering is turned on for a chart, you can filter the report by interacting with that chart in several ways:
    • Clicking one or more dimension values in the chart
    • Dragging, or "brushing," your mouse across a time series, a line chart, or an area chart
  • Change sorting — Lets you change the way data is sorted in the chart.
  • Zoom — Lets you zoom and pan to view sections of data across the chart.

Google Analytics segment

This option appears for charts based on a Universal Analytics data source.

A segment is a subset of your Analytics data. You can apply segments to your Looker Studio charts to help ensure that your Looker Studio and Google Analytics reports show the same data. Learn more about Analytics segments in Looker Studio.

Style the chart

The options in the Style tab control the overall presentation and appearance of the chart.

Title

If you select the Show title checkbox, you can add a title and customize its appearance and placement on the chart.

Series

This section repeats for each metric that is displayed in the chart. The order of sections matches the order of the metrics that are listed in the DATA tab.

Line weight — Select the Line weight icon to specify the thickness for the border of the box portion of the chart.

Series color — Select the Series color icon to select a fill and border color for the box and wick portions of the candlestick chart.

Add a reference line or a reference band to your chart by selecting the Add a reference line or Add a reference band option.

This option lets you limit the number of data points that are displayed by the candlestick chart. Input a number into the text box to limit the number of data points displayed. 

For example, if you input the number 3, only three boxes will appear on a chart.
