Overview
The Chart By Category X widget generates interactive visualizations based on categorical data within your experimental records and sections. By leveraging Select or ForeignKey columns to categorize data, this widget displays record counts or aggregated numeric values across different categories, making it ideal for analyzing distributions, comparing groups, and tracking trends. With support for multiple aggregation methods (sum, average, max, min, median), flexible axis formatting, and optional grouping capabilities, this widget transforms tabular data into clear, actionable insights directly within your laboratory workflows.
Use Cases

Read-only View
The read-only view displays an interactive bar chart with categories on the x-axis and counts or aggregated values on the y-axis. The visualization is contained within the section and automatically updates based on your configuration settings.
Data Display: Bar chart showing categorical data with clearly labeled axes and color-coded series
Interactive Features: Hover over bars to view exact values and category labels
Chart Interactions: Visual representation updates dynamically when underlying data changes (if auto-update is enabled)
Export Access: Download button available for extracting source data for external analysis
Edit View
The edit view is not applicable for this widget as it is designed purely for data visualization and reporting. All configuration and customization is performed through the widget settings panel accessible via the configure button in the widget header. The widget automatically generates visualizations based on the configured parameters without requiring direct editing of the chart itself.
Configuration
Initial Setup
Add the Chart By Category X widget to your section by clicking Add Widget and selecting Chart By Category X from the Data Driven Charts category
Click the Configure button or settings icon in the widget header to open the configuration panel
Configure the data source and visualization parameters as described below
Required Settings
These settings must be configured for the widget to function properly:
Table: Select the table that contains the data you want to visualize. This selection updates the available columns in other configuration options
Optional Settings
Customize your visualization with these optional parameters:
Data Filtering and Source
Query: Enter a query string to filter which records are included in the chart. Leave empty to include all records from the selected table
X axis: Choose a column for the x-axis categories. Select or ForeignKey columns work best for categorical data. If nothing is selected, the record name will be used as the x-axis
X Axis Configuration
X axis sorting: Define how categories are ordered on the x-axis
String (A-Z): Alphabetical ascending order
String (Z-A): Alphabetical descending order
RID (Ascending): Sort by record ID in ascending order
RID (Descending): Sort by record ID in descending order
X axis format: Control how ForeignKey values are displayed on the x-axis
Full (UID: Name): Shows complete reference (e.g., 'TRT24: Untreated Control')
Name only: Shows only the name portion (e.g., 'Untreated Control'), grouping records with identical names together
Data Series and Aggregation
Series: Choose one or more columns for the data series. Number, Formula, or Consumption widgets must be used in the column. If no series is selected, the widget displays record counts by default
Group: Select a column to create grouped visualizations. When a group is specified, the x-axis values become categories, group values become series, and series values are aggregated for each combination, enabling multi-dimensional analysis
Data aggregation: Define how numeric values are combined
None: Display raw values without aggregation
Sum: Calculate the total of all values (default if no series is selected)
Average: Calculate the mean of all values
Max: Display the maximum value
Min: Display the minimum value
Median: Calculate the median value
Visualization Customization
Chart title: Provide a descriptive title for your chart. This title appears at the top of the visualization
Height: Set the chart height in pixels. Default is 250px. Adjust based on the complexity of your data and available section space
Auto-Update Settings
Should auto update: Enable to automatically recalculate and refresh the chart when underlying data changes, ensuring visualizations stay current with laboratory data
Should auto update when empty: Enable to automatically perform calculations even when the widget initially has no data
Select your Table to define the data source
Choose an X axis column to define your categories (Select or ForeignKey columns recommended)
Optionally select a Series column to aggregate numeric values, or leave empty to count records
Configure X axis sorting and X axis format to control category display
Select a Data aggregation method if you're working with numeric series
Add a Chart title and adjust Height as needed
Enable Should auto update if you want real-time chart updates
Click Save to apply your configuration
The widget requires at least one column with a Select or ForeignKey widget for categorical data. For numeric aggregation, you'll need columns with Number, Formula, or Consumption widgets.
Advanced Configuration
For complex analytical scenarios:
Use the Group option to create multi-dimensional visualizations with categories, groups, and aggregated series
Combine Query filters with X axis selections to focus on specific data subsets
Use X axis format set to "Name only" when working with ForeignKey references that share common names but different IDs
Experiment with different Data aggregation methods to discover various insights in your data
Complex configurations with many categories, groups, or large datasets may affect chart rendering performance. Consider using Query filters to limit data scope if performance issues arise.
Additional Functions
Data Export
Export the underlying data used to generate your chart for external analysis or record keeping:
Locate the Download button in the widget interface (typically in the widget header or below the chart)
Click Download to export the aggregated data
Save the downloaded file to your desired location
The exported data includes:
Category values from the x-axis
Aggregated or count values for each category
Group information if grouping is configured
Series data if multiple series are selected
Use exported data for:
Import into external analysis tools (Excel, R, Python, GraphPad)
Creating custom reports and presentations
Archive analytical results for compliance documentation
Share insights with stakeholders who need raw data
Auto-Update Functionality
The Chart By Category X widget supports automatic chart refreshing to keep visualizations synchronized with changing data:
Enable Should auto update in the widget configuration
The widget will monitor the source table for changes
When data is added, modified, or deleted, the chart automatically recalculates and refreshes
No manual intervention is required to see updated visualizations
Auto-update is particularly useful for monitoring ongoing experiments, tracking real-time progress, or displaying live quality control metrics.
Auto-Update When Empty: Enable Should auto update when empty to automatically populate the chart even when first added to a section without initial data. This is useful for template sections that will collect data over time.
Chart Type Flexibility
While the default visualization is a bar chart, the underlying data structure supports multiple chart type interpretations:
Bar Charts: Best for comparing discrete categories
Grouped Bar Charts: When using the Group option for multi-dimensional comparison
Stacked Visualizations: When working with multiple series that represent parts of a whole
The widget automatically selects the most appropriate visualization based on your configuration.
Best Practices
Data Organization
Categorical Clarity: Use Select or ForeignKey columns with clear, descriptive category names for optimal x-axis labeling
Consistent Categorization: Ensure categorical data is standardized across records to avoid fragmented visualizations
Limited Categories: Aim for 5-15 categories on the x-axis for readability. Use Query filters to narrow scope if you have too many categories
Meaningful Grouping: When using the Group option, choose grouping columns that provide analytical value and don't create excessive complexity
Performance Optimization
Query Filtering: Apply Query filters to limit records and improve chart rendering speed, especially for large datasets
Strategic Auto-Update: Use auto-update selectively for sections where real-time data is critical, as it consumes additional resources
Height Optimization: Set appropriate chart heights based on the number of categories to ensure readability without excessive scrolling
Aggregation Selection: Choose the most appropriate aggregation method for your data type to ensure meaningful results
Analytical Strategy
Start Simple: Begin with record counts before adding numeric series and complex aggregations
Progressive Enhancement: Add grouping and multiple series incrementally to understand data relationships
Appropriate Aggregation: Match aggregation methods to your analysis goals (sum for totals, average for typical values, max/min for ranges)
Sorting Strategy: Use meaningful x-axis sorting (alphabetical for names, RID for chronological)
For treatment comparison experiments, use the Group option to visualize multiple measurements (replicates) across treatment categories, with aggregation set to Average for typical response values.
Common Pitfalls to Avoid
Avoid: Selecting text or rich text columns for the x-axis, which can create cluttered or meaningless categories
Instead: Use dedicated Select or ForeignKey columns designed for categorical data
Avoid: Using "Name only" x-axis format without understanding it groups different records with the same name
Instead: Use "Full (UID: Name)" format when you need to see distinct records, use "Name only" only for intentional grouping
Avoid: Displaying too many categories (20+) on a single chart
Instead: Apply Query filters to focus on relevant subsets or create multiple charts for different category groups
Visualization Best Practices
Clear Titles: Provide descriptive chart titles that explain what data is being visualized and the aggregation method
Appropriate Height: Adjust chart height based on the number of categories – more categories need more vertical space
Logical Sorting: Sort categories in a way that enhances understanding (alphabetical for comparison, RID for chronological trends)
Color Coding: When using groups or multiple series, ensure the resulting color coding is distinguishable
