Tableau desktop description
Tableau Desktop is a powerful tool for developing compelling visualizations and creating interactive dashboard. The main benefit of using Tableau Desktop is that it doesn't need any technical expertise. In fact, the advantages of using Tableau Desktop is summarized in this graph.
As a result, Tableau Desktop brings a user-friendly platform for data visualization and developing interactive dashboards and story-telling that could be connected to your database seamlessly.
Main tableau desktop interface
The main Tableau Desktop interface is shown here:
Section A: This pane contains all the headers of your data, split into Dimensions and Measures. Typically, dimensions are your main variables and are almost always discrete data. Measures are usually measurements, often continuous data that are dependent on dimensions.
Section B: This pane contains the Columns and Rows shelf. Tableau is almost all drag-and-drop. You can drag dimensions and/or measures to these shelves to build a graph.
Section C: This is the pane where a graph will show up. If empty, you can drag a dimension / measure directly to this area.
Section D: This pane contains the Filters shelf and Mark control. Marks are Tableau’s name for data-points. You can modify the look of data-points by adding dimensions to “color” or “size” or just clicking on these buttons. Filters are an option to crop out or refine the data. Drag a dimension or measure to the Filters shelf in order to filter the data being graphed.
