Histogram in Tableau

Histogram is a graphical representation that organizes a group of numerical data points into ranges (bins). Each bin is represented as a bar and the height of the bar corresponds to the frequency of data points within that range. Unlike bar charts, histograms have no gaps between bars, showing continuous data distribution.

Creating a Basic Histogram

To create a basic histogram in Tableau, we need to:

1. Open Tableau and connect to the dataset.
2. Drag and drop a sheet from the connected dataset.
3. Open a worksheet (for example, Sheet1).
4. On the left side, we will see all dataset attributes.
5. Select at least one numerical field and drag it into Columns or Rows.
6. From the chart options, select Histogram as the chart type.

This creates a basic histogram that shows the frequency distribution of the selected numerical field.

Note: You can use in-built datasets of tableau.

Example 1: Histogram of Discount

1. Select the Discount field for Columns.
2. Select Discount again for Rows.
3. Choose Histogram from the chart options.

This gives a simple view of how frequently different discount values occur in the dataset.

Example 2: Histogram with Market Color

To add more context to the histogram:

1. Select Discount for Columns and Rows.
2. Choose Histogram as the chart type.
3. Drag Market to Color in the Marks section.

This histogram allows us to see the distribution of discount values across different markets, adding an additional layer of analysis.

Example 3: Histogram with Profit, Market and Region

For a more advanced visualization:

1. Select Discount for Columns and Rows.
2. Choose Histogram as the chart type.
3. Drag Profit into Rows to include profit distribution.
4. Drag Region into Color to differentiate regions.
5. Drag Market into Text in the Marks section to label each bar.

This advanced histogram shows discount distribution, profit values and allows differentiation by region and market, providing a multi-dimensional view of the data.

By customizing the histogram with color, labels and additional fields, we can gain deeper insights into the data and analyze it across different dimensions like market, region or profit.
