The Gantt chart enables you to present time-dependent data in an intuitive graphical manner, from a hierarchical and/or resource-oriented viewpoint. It shows the user the sequence in which various activities occur and the dependencies between these activities. The user can easily see the start and end of a particular activity.

The Gantt chart control provides the basis for creating such a Gantt chart and is a generic tool. Applications can consume the control in order to implement their use cases, and if necessary, they may even enhance the control.

It consists of three areas: a chart area, a table area, and a global toolbar.

Another feature is the option to have a split screen that includes two or more views next to one another, each view consisting of one table and one chart. These views can be arranged vertically or horizontally, and they share a common (global) toolbar. To see an example of the dual view, check out the SAPUI5 highlights video.

Use the Gantt chart if:

  • You want to build an interactive and complex planning application involving activities, resources, hierarchical project structures, relationships, and other basic shapes such as diamonds, utilization line charts, or bar charts.
  • You want to build a simple application which may be read-only or which does not have a table component.
  • You want to build a simple application that is also capable of evolving into a more powerful application later on.

Do not use the Gantt chart if:

  • Your application needs to run on a smartphone. Consider using the planning calendar control instead.
  • You need to show less than 100 rows. You can still use a Gantt chart, but consider using the planning calendar control instead.
  • You want to show only a simple graphical representation based on rectangles (in other words, without relationships, milestones, and so on). Consider using the planning calendar control instead.

Responsiveness and Adaptiveness

The Gantt chart is responsive in principle. It can be displayed in a small window (size M) and preserve its layout without needing to create multiple levels of scroll bars nested in one another in the browser window. However, the control is not available in smartphone size (size S).

The Gantt chart control can be used to display data in tablet (size M).

Cozy and Compact Modes

The Gantt control supports the cozy, compact and condensed modes. For more information, see content density.


The buttons contained in the optional global toolbar can control the behavior of the entire Gantt chart across multiple views. Each view can contain a local toolbar. This local toolbar is optional and is located above the tree table.

The buttons contained in the local toolbar can only control the behavior of its corresponding view. Each view can contain a tree table to the left and a chart to the right. However, the tree table is optional and the chart area can stand on its own.

The Gantt chart consists of three areas: a global toolbar, a table area, and a chart area. There can be more than two table and chart areas in a split-screen layout.

Global Toolbar

The global toolbar provides standard functions, which are required by several applications. However, app teams can add extra functions. The user can also hide certain standard functions.

The following standard functions are available:

  • Legend (see details below)
  • Settings (see details below)
  • Zooming (see details below)
  • View combination switch: This dropdown menu is shown only if the consuming application provides more than one view combination.
  • View arrangement: Hide one of multiple views; add views; switch between vertical and horizontal alignment of the views. This can be skipped by the consuming application.
  • Overflow behavior: The global toolbar has the same overflow behavior as the SAPUI5 toolbars. For more information, see toolbar overview.

For the legend, we provide two templates to address fast implementation in most use cases:

  • List template: Displays a list of shapes and their corresponding texts. You can also add a checkbox before each shape, which allows the application to control if the shape will be displayed in the chart.
  • Dimension template: Shows a matrix of shapes and their corresponding texts for varied combinations of two dimensions.

The control offers some standard settings (such as Indicate Current Time, Show Cursor Line, Show Divider Lines, and Synchronize Time Scroll). The app team can also insert their own settings into the settings dialog. The user can configure the display of the Gantt chart using the setting options. In addition to the default setting options, the app team can add more options to control the behavior of the Gantt chart.

The control provides a zooming function for the chart area. It consists of a Zoom In/Zoom Out magnifier buttons and a slider. You can hide the slider if there is not sufficient room for it, for example in size M. The zooming function also controls the labelling of the time axis, which determines whether you see years, months, or days. For more information, see time axis.

Chart Area

The chart area that includes the Gantt chart comprises a time axis and rows that contain different shapes. The position of a shape on the time axis depends on the dates of the object represented by the shape.


The chart area is closely connected to the table area. This means a line in the table corresponds to a line in the chart. Selecting a row in the table also selects this row in the chart. The height of the line is the same in both areas. If the user scrolls in one area, the other area scrolls in exactly the same manner.

Time Axis

The chart control can display the time axis in different time measurements as defined by the consuming application. Every time axis should have two levels. The app team can define the formatting of the labels for the times axis. The formats defined by SAPUI5 are supported. The Gantt control provides a default configuration for the time axis.

For more information, see time axis.

As shown in the above examples, you can display a vertical line indicating the current date. The actual date can be displayed on the axis. It’s also possible to show non-working time frames, such as weekends, by graying out these time frames. These dates can vary from line to line.

Basic Shapes

The Gantt control offers these basic shapes:

  • Rectangle
  • Polygon
  • Line (for example, to show notifications for rectangles)
  • Triangle (for example, to represent constraints such as time windows)
  • Diamond (for example, to represent milestones)
  • Chevron (for example, to represent project phases)
  • Cursor (for example, to represent checklist items)
  • Image (for example, to place images in the chart)
Basic shapes: rectangle, line, chevron, polygon, cursor, diamond, triangle
Basic shapes: rectangle, line, chevron, polygon, cursor, diamond, triangle

These shapes can also be combined. The chart control can render the shapes with different border and fill styles and border and fill colors, and use gradients. For more information, see colors.

App teams can add their own shapes, but they must adhere to the chart guidelines on colors. In general, you should use the qualitative palette, but if you need more colors, use the sequential palette.

When choosing the colors and hues to represent different object types, remember to select those that have a significant contrast.

The most commonly used shape is the rectangle (or bar).

Although it is technically feasible to use two bars above and below each other in one row, we do not recommend this practice. Particularly with high screen resolutions, this can lead to visual crowding so that the user cannot discern between different elements.

For example, if you want to show the degree of completion in a bar, it may be better to superimpose the finished section using a different shade over the original task.

Example of completion in a bar

You can link two shapes with a line in various styles and colors. The exact meaning of the relationship depends on the use case and the application. However, it usually implies that one activity has to be performed or at least started before the subsequent activity can begin.

  • A relationship can begin from the start or end date of a shape.
  • A relationship can end at the start or end date of a shape.
  • The end of a relationship is shown using an arrow.
  • One shape can have multiple relationships.

The app team should define the logic of a relationship, such as rescheduling.

Utilization Chart

The utilization line chart and utilization bar chart enable you to display the level of consumed capacity of a resource at a specific point in time.

The system displays the utilization curve of the selected resource in the chart panel. You are notified of low load utilization and over-capacity by predefined colors. Moreover, the tooltip along the utilization curve displays the utilization of a resource in specific aspects according to your settings. You can customize it to fit your business needs, for example, to display the loading utilization of a vehicle resource in terms of volume or weight.

Use line widths large enough for the user to distinctly recognize the line. Avoid using dotted or dashed lines whenever possible.

Table Area

The Gantt control contains a table area that allows you to display and edit details of each line. For example, you may want to edit dates using a date picker rather than dragging a shape into the chart area. The table used in the control is the SAPUI5 tree table.

Behavior and Interaction

Various tooltips can be shown, but you should not use them to show additional information because users cannot access this functionality on touch devices.

The Gantt chart supports various events, allowing you to build rich and interactive applications.

Shape Selection

When a shape (including relationships) is clicked, the shape is highlighted and an event is raised. The application can provide respective event handling to catch the event and perform tasks as needed, such as showing an action sheet, or showing a detailed information popover. A parameter is provided to enable three different selection behaviors for different usage environments:

  • Single selection of the shape via clicking
  • Multi-selection of the shapes via clicking
  • Multi-selection of the shapes via pressing CTRL key and clicking
Multi-selection of shapes
Multi-selection of shapes

Shape Drag and Drop

When you click on a shape and hold the mouse in the chart area, a shadow of the shape moves along the mouse. When you release the mouse, an event is raised, and then the application can provide an event handler to catch the event and perform tasks as needed, such as moving the shape to a new position. You can also drag and drop the shape across different views inside the same Gantt chart or even outside the Gantt chart; it’s also possible to drag-and-drop multiple selected shapes, for more information, you can check the SAPUI5 high light video here.
