Visualisations | DAL4 RS A3.1 |

All reports and dashboards use visualisation to represent and communicate perspectives or views of data. Tableau visualisations are directly connected to the underlying data sources so they will update if the data source is refreshed (or kept as a live connection). In dashboards, visualisations can be pinned into a single view from multiple reports and data sources. They are normally linked together via filters and actions to enable the end user to drill into their data and discover specific and actionable insights. The demo Tableau workbook provided here contains a dashboard where each visualisation is connected to the others in a specific way:

Tableau offers a limited number of out of the box visualisations via the Show Me menu on the Worksheet view, in which the required data fields and types are indicated and the recommended visualisation for the currently selected data items is highlighted.  The chart types that are greyed out are not appropriate for the currently selected data fields. If nothing is showing, ensure that you have selected fields in the Tables pane first. You can multi select in Tableau using Ctrl and Select (for Windows) or Cmd and Select (for Mac).

In addition to the Show Me Menu, the Marks Card has a drop-down menu for mark type which can be used to determine how the visualisation represents the data selected, when changed from Automatic type. In this menu there is a pie chart mark type, along with shapes, lines, bars, squares or circles. To complete the visualisation, it can be necessary to modify the fields in other elements of the design canvas, including the row and columns shelf; in this way an unlimited number of visualisations can be plotted.   

Tableau visualisations can be formatted further to reach the required output, using the marks card and formatting menus. After installing, a Tableau Repository folder is created on the C:drive which enables custom colour schemes and shapes to be imported to the tool in the Preferences file or Shapes folder.

For more ideas of what visualisations can be designed in Tableau, the best resource is to view the Viz of the Day gallery in Tableau Publica curated selection of the best vizzes from the Tableau Public community, mostly dashboards and stories and occasionally very complex chart types. You will discover an interactive Tableau viz cookbook on Tableau Public which shares the ‘recipes’ to many popular plot types.
