Exploring and Analysing Data
Bar charts are an excellent way to visualize your information, and Tableau gives you many options to display your data exclusively. You can draft a bar chart by placing a dimension on the Rows shelf and a measure on the Columns shelf, or the opposite.
Initially, you may only be creating basic, Clustered, Stacked, Dual Axis, Combo, and Diverging bar charts. Distinct charts have different importance. If you want to match the sales across many dimensions, then you want a grouped bar chart. Viewing your measure by two aspects creates the grouping or clustered bar chart view. Dual-axis bar charts (also known as bullet charts) are a great way to compare two different measures with just one dimension. Stacked charts are a combination of a stacked bar chart and a grouped bar chart. The Diverging bar chart style takes a more efficient to design, but it’s a powerful way to compare the difference of one measure amid two dimensions.
Tableau enables you to organize data and apply filters. Filtering is an essential part of analyzing the data. Let us understand how you can display interactive screens in the view, and format filters in the picture.
Tableau performs actions on your view in a particular order; this is called the Order of Operations. Filters are in the following order:
Extract filter
Data source filter
Context filters
Filters on dimensions (whether on the Filters shelf or in filter cards in the view)
Filters on measures (whether on the Filters shelf or in filter cards in the picture)
You can filter individual data points (marks), or a selection of data points from your perspective. Whenever you add a filter to a worksheet, it automatically applies it to the current sheet. Sometimes, however, you may want to apply the filter to other sheets in the workbook. You can select specific sheets to apply the filter to or apply it globally to all sheets that use the same data source or related data sources.
Also, you can create a group to combine related members in a field. There are numerous manners to create a group. You can create a group from an area in the Data panel, or by selecting data in the view and then by clicking on the group icon.
It is essential to understand the application of analysis to a worksheet. In Tableau Desktop, choices for adding Analytics objects to the view are available the Analytics pane or menu, or in the context in the picture. For example, reference lines and bands are open when you make changes to the axis, and trend lines and forecasts are present in the Analysis menu. You can drag reference lines, box plots, trend lines forecasts, and other items into your view from the Analytics pane, which appears on the left side of the workspace. Under this, you can:
- Add a manual or a computed sort
- Add a reference line or trend line
- Use a table calculation
- Use bins and histograms
- Create a calculated field (e.g., string, date, simple arithmetic)
- Add a parameter
