Tableau is a trending and market-leading Business Intelligence (BI) tool that is used to visualize data in an easily digestible format. It is used by most of the Fortune Global 500 companies in order to derive valuable insights from their data.
Tableaus major advantage over Excel is that it allows you to create interactive dashboards which are visually attractive. It also provides a drag-and-drop feature that makes working with large-scale data easy and quick.
This feature helps you save time by allowing you to work with the live data-set rather than wrangling the data. It also helps you to spend more time on analysis and thereby increase your productivity.
You can make use of data blending to combine multiple related data sources and represent them in a single view. You can also use this feature to analyze and present a single set of data in different visualizations, including bar charts, treemaps and maps.
One of the most common uses for this feature is reporting, which allows you to interpret information quickly and efficiently by using visual aids. This can be done at current snapshots, such as total turnover, number of recurring customers or most popular products, or over specified periods of time, like sales trends by region and order dates.
Other common uses for this feature are exploratory data exploration and ‘what if’ questions. This is because you can hypothetically visualize your data in different ways, and then dynamically add components to compare and analyze it.
In addition, it can be used to clean-up bad data by highlighting errors and outliers more effectively than grids of text in a spreadsheet. This is especially useful when you are trying to determine the causes of a problem or find out where a data source is falling short in some way.
Another advantage of this feature is that you can easily export your dashboards to PDF files, which you can share with others through email or instant messaging. This also lets you analyze your data in an offline mode when you need to improve your performance.
This feature is a great way to communicate your work and inspire new users to learn the tool. It also helps you to showcase your work and show how it has changed the way people understand your data.
To create a butterfly chart in Tableau, you must first select the data you want to include in your chart. Click on the Columns shelf and select the fields.
Next, select the axis you want to display and double-click on it. You can also right-click and choose Edit Axis.
Then, you can customize the scales of each axis. For example, you can change the start and end of the first axis to make it easier to compare.
You can also choose a color palette for the chart. For example, you can change the background to blue or red to create a more visually interesting display.
You can also add markers or text to the chart by dragging the data into the relevant Marks card. For instance, you can add “Birth Rate of Age 20-25” or “Birth Rate of Age 30-35”.
