The scatter plot is used to visualize the relationship between the two measures. It is designed by adding measures in both x-axis and y-axis. This can show the trend or relationship between the measures selected.
To create a scatter plot, you should have at least one measure in the rows shelf and one measure in the columns shelf. However, you can add the dimensions field to the scatter plot that plays a role of different color making for already existing points in the scatter graph.
For example, consider the data source such as Sample-Superstore, if you want to find the variation of Sales field and Profit field as the two axes of the Cartesian plane is distributed according to their Sub-Category field.
To create a scatter plot, there are the following steps, such as:
Step 1: Drag the measure Sales and drop into the columns shelf.
Step 2: Drag the measure Profit and drop into the rows shelf.

Step 3: Drag the dimension Sub-Category and drop into the Label shelf under the Marks pane.

After that, it creates the scatter plot that shows how the Profit field and Sales field is distributed across the dimension Sub-Category of products.

Step 4: You can also get the values color encoded after dragging the Sub-Category field into the Color Shelf.
Below chart appears that show the scatter points with a different color for each point.

The same scatter plot can show different values when you choose a dimension with hierarchy.
For example, expand the dimension Sub-Category to show the scatter plot values for the Manufacturers field.

Histogram

A histogram chart is a chart that displays the shape of the distribution.
A histogram looks like a bar chart but group values for a continuous measure into range. In the histogram, each bar represents the height of the number of values present in that range.
To create a histogram, we need only one measure. It creates the additional bin field for the measure.
For example, consider the data source such as Sample-Superstore, and if you to find the Quantities of sales for different Segment. For this, follow the below procedure step by step, such as:
Step 1: Go to the worksheet.
Step 2: Drag the measure Quantity into the columns shelf.

Step 3: Click on the “show me” toolbar and select the histogram chart icon, shown in the below screenshot.

NOTE: The histogram chart is available in “show me” when the view contains only one measure and no dimensions.

Step 4: After selecting the histogram chart as the chart type. Then,
• The view changes and shows vertical bars, with a continuous X-axis and Y-axis.
• The measure Quantity with SUM aggregate in columns shelf is replaced by continuous Quantity(bin) dimension.
• The Quantity field moves to the rows shelf and aggregation changes from SUM to CNT or (Count).

Step 5: Drag the dimension Segment and drop into the Color shelf under the Marks pane.

After adding the Segment field to Color shelf, you can see a relationship between the Segment field and the Quantity of item as per order is shown in the below screenshot.

Step 6: Hold the Ctrl key in the keyboard and drag CNT(Quantity) field from the rows shelf Label shelf under the Marks pane.

Step 7: Right-click on the CNT(Quantity) field in Marks pane. And
• Click on the Quick Table Calculation option from the list.
• Select the Percent of Total option.

Now each colored section of each bar shows its percentage of total quantity shown in the following screenshot.
