You can use the fields panel in a Data Engineering view to work with the fields in layers and tables. The fields panel lists the layer or table fields, including their properties and options, to visualize each field using symbology and charts.
Learn how to open a data engineering view
Display a list of fields
After you open the data engineering view, the fields panel displays field aliases of all the visible fields of the selected layer or table. Each field listing includes an icon corresponding to the data type for each field.
You can specify which data types are displayed by applying filters using the filter button 
at the top of the panel.
You can search for specific fields by entering text in the Search Fields text box 
.
To change the displayed field aliases to field names, click the menu button 
and uncheck Show Field Aliases.
Update symbology based on fields
You can visualize the fields of a feature layer in your map using the data engineering view. By displaying fields on a map, you can explore where features are located, how values are distributed in space, and whether any places are missing data.
In the fields panel, you can update the map symbology using the Update Symbology option 
.
- In the fields list, hover over a field and click Update Symbology to update the symbology for that field.
The default symbolization method is based on the data type of the selected field.
Field data type Default symbology Numeric (short, long, float, double)
Graduated colors—Show quantitative differences in feature values with a range of colors. The default classification method is Natural breaks (Jenks) with four classes.
Text or date
Unique values—Apply a different symbol to each category of features in the layer based on one or more fields. Only the first 100 unique values are given a unique symbol; all other values are grouped together.
- To further configure the symbol properties, right-click the field in the fields panel and click the Symbology button
or click the Symbology button on the Map ribbon. The symbology pane appears with the method and field name populated by default.
- To revert to the original symbology, use the undo action on the Quick Access Toolbar.
Create charts based on fields
You can visualize and explore your data using charts, which help reveal patterns, trends, relationships, and structure in the data. Use charts together with maps to tell a story from your data. In the fields panel, you can create charts for a single field using the Create Chart option 
or for a multiple fields using the Create Chart menu.
- In the fields list, hover over a field and click Create Chart to create a chart for that field.
A default chart is created based on the data type of the selected field. The chart's properties pane also appears, allowing you to further configure the chart's appearance.
Field data type Default chart type Numeric (short, long, float, double)
Histogram—Visualize the distribution of values in a numeric variable by grouping numbers into bins and measuring the frequency of those groups.
Text or date
Bar chart—Summarize and compare categorical data.
Date
Line chart—Visualize change over a continuous time range.
- Optionally, right-click the selected field and click Create Chart to learn about other chart types are available for the field.
A list of available charts are displayed in the menu.
- Optionally, select multiple fields in the panel to create charts.
For example, select two fields, right-click, and click Create Chart to create a scatter plot, a scatter plot matrix, or a box plot.
Access the Data Engineering tools
Several geoprocessing tools have been grouped into four categories for data engineering: Clean, Construct, Integrate, and Format. You can access these categories and their tools from the Data Engineering ribbon. To access tools applicable to a field’s data type, select a field in the fields panel and right-click.
Note:
Most geoprocessing operations that modify the input data cannot be undone.
