Sankey charts are a type of flow map that are used to illustrate the flow of information or data in a specific direction. They are a great way to visualize complex data and quickly grasp the overall flow of information or data. In this article, we will explore the power of sankey charts and provide a visual guide to understanding how to create and apply these charts in data analysis.
A guide to sankey charts
Sankey charts are a type of flow map that have become increasingly popular in recent years due to their ease of use and the ability to quickly convey detailed information. They are a visual representation of the flow of data in a specific direction, which can be useful when analyzing large amounts of data or when studying complex processes. In a sankey chart, the arrows represent the direction of flow, and the nodes represent the sources and destinations of information or data. For example, you could use a sankey chart to visualize the flow of information between a website and its visitors, or the flow of data from a database to a reporting tool.
Creating sankey charts
Creating sankey charts requires a bit of coding or designing skills, but it is relatively easy to learn. To create a sankey chart, you will need to use a spreadsheet program such as Microsoft Excel, Google Sheets, or Numbers, or a software program such as Tableau or Power BI. Once you have chosen a spreadsheet program or software program, you will need to create a flow map for the data you want to visualize. You will also need to select the colors and labels for the nodes and arrows to make the chart easy to read.
An example sankey chart
Let’s take a look at an example sankey chart to help illustrate how sankey charts work. The chart shows the flow of information between a company and its suppliers. The arrows represent the flow of information or data, and the nodes represent the sources and destinations of information or data. In this example, the flow of information from the company to its suppliers will be represented by a downward arrow, and the flow of information from suppliers to the company will be represented by an upward arrow.
Creating a sankey chart in excel
To create a sankey chart in Excel, you will need to first create a flow map for the data you want to visualize. Once you have done so, you can select the nodes and arrows for each flow in the chart and format them with colors and labels as desired.
An example sankey chart in excel
To create a sankey chart in Excel, open a file with your flowing data and insert a new chart that displays the flow map. In the dialog box that appears, select “Sankey Chart” as the chart type and adjust the settings as needed, such as the flow direction and the labels for the arrows and nodes.
Applying sankey charts in data analysis
Sankey charts can be applied in a variety of different fields, including data analysis, marketing, and healthcare, to name a few. They are particularly useful in identifying the flow of information or data in a specific direction and可以帮助你quickly grasp the overall flow of information or data. They can also be used to identify patterns and relationships in data, and can provide insight into complex processes.
Conclusion
