Bar chart in DataLens On-premises

A horizontal bar chart plots the values of one or more measures for each category.

The length of a bar reflects the measure value: the longer the bar, the larger the value.

Types of bar chartsTypes of bar charts

• Grouped
• Stacked

GroupedGrouped

You can use a chart grouped by dimension to compare the values of a single measure for two or more categories.

• For example, grouping by delivery type allows you to compare the cost of products delivered by courier and picked up. Categories are highlighted in different colors and the length of the bar indicates the measure value.

  Subcategory	Delivery	Pickup
  Beauty and health products	12K	32K
  Kitchenware	394K	998K
  Kitchen products	371K	749K
  Detergents	127K	278K
  Health and beauty equipment	497K	1,263K
  Non-essential goods	268K	560K

• Use a grouped chart to compare two or more measures, e.g., the number of orders and the number of products. The bar length corresponds to the measure value.

  Subcategory	Orders	Number of products
  Beauty and health products	481	1,470
  Kitchenware	758	2,402
  Kitchen products	480	1,371
  Detergents	835	2,551
  Health and beauty equipment	863	2,705
  Non-essential goods	705	2,152
  Cleaners	770	2,460

StackedStacked

A stacked chart shows a ratio of internal segments to the total value.

• Segments are placed one after another, where the beginning of each next segment is the outer boundary of the previous one.

• Use this chart type to see how each measure contributes to the total by period or category, e.g., to view the percentage of each expense category in the total budget.

Wizard sectionsWizard sections

Wizard section	Description
Y	Dimensions. You can specify one or two dimensions.
X	Measure. You can specify multiple measures. If you add more than one measure to a section, the Colors section will contain a dimension named Measure Names. You can move Measure Names to the Y axis.
Colors	Measure Names dimension or field. Affects the column color. To delete Measure Names, click the cross icon or remove measures from the X axis.
Sorting	Dimension or measure. Affects the column sorting. The sorting direction is marked with an icon next to the field: for ascending or for descending. To change the sorting direction, click the icon.
Labels	Measure. Displays measure values on the chart. If multiple measures are added to the Y section, drag Measure Values to this section. Markup functions are supported. For String type fields, you can configure using basic Markdown in DataLens On-premises syntax: click the icon before the field name and enable Markdown.
Filters	Dimension or measure. Used as a filter.

Creating a bar chartCreating a bar chart

To create a bar 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 Line chart as the chart type.
6. Drag one or more dimensions from the dataset to the Y section. The values will be displayed on the Y axis.
7. Drag one or more measures from the dataset to the X section.
8. Drag a dimension from the dataset or the Measure Names field to the Color section.

A stacked column chart is displayed by default.

Creating a grouped bar chartCreating a grouped bar chart

To display an Y-axis grouped bar chart:

1. Go to the bar chart that you created.

2. Depending on the number of measures in the X section, follow these steps:

   Single measure

   Two or more measures

   1. Check if there is a dimension in the Colors section.
   2. Duplicate this dimension in the Y section. The sequence of dimensions affects the grouping order.

   1. Drag the Measure Names dimension to the Colors section.
   2. Drag the Measure Names dimension to the Y section. The sequence of dimensions affects the grouping order.

Adding a column color based on a measureAdding a column color based on a measure

To color columns in a chart based on the value of a measure:

1. Go to the column chart that you created.

2. Depending on the number of measures in the X section, follow the steps below:

   Single measure

   Two or more measures

   Copy the measure from the X section to the Colors section.

   The colors of the columns in the chart will apply based on the measure values.

   Example

   

   Drag the Measure Values measure to the Colors section.

   The chart columns will be colored based on the values of all measures listed in section X.

   Example

   

3. Configure a color gradient for the measure as well. To do so, in the top-right corner of the Colors section, click (the icon is displayed when you hover over the section).

4. In the color settings, specify:

   • Gradient type: Select two or three colors.
   • Gradient color: Select a color palette for the gradient from the list.
   • Gradient direction: Change the gradient direction using the icon.
   • Set threshold values: Set numeric thresholds for each color. Works if the X section contains a single value.

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.

• Place segments inside bars so that the largest or most important categories are located to the left, closer to the chart's Y-axis. This makes it easier to compare the values.

• Dimension or measure. It affects the intensity of point fill.
