Introduction

As a GIS professional, you're likely familiar with the power of graduated colors in ArcGIS Pro for visualizing complex data. However, with the release of ArcGIS Pro 3.4.0, some users have reported issues with using graduated colors for line feature classes. In this article, we'll explore the challenges of using graduated colors for line feature classes in ArcGIS Pro 3.4.0 and provide some workarounds to help you achieve the desired visualization.

Background

Graduated colors are a powerful tool in ArcGIS Pro for creating visually appealing and informative maps. By using graduated colors, you can quickly identify patterns and trends in your data, making it easier to communicate insights to stakeholders. However, when working with large datasets, such as line feature classes with over 300,000 features, graduated colors can be computationally intensive, leading to performance issues.

The Issue with Graduated Colors in ArcGIS Pro 3.4.0

When you try to use graduated colors for a line feature class in ArcGIS Pro 3.4.0, you may encounter the following issues:

Slow performance: Graduated colors can take a long time to render, especially when working with large datasets.
Error messages: You may receive error messages indicating that the graduated colors are not supported for line feature classes.
Inconsistent results: Even if you manage to apply graduated colors, the results may be inconsistent or incorrect.

Causes of the Issue

There are several reasons why graduated colors may not work as expected for line feature classes in ArcGIS Pro 3.4.0:

Computational complexity: Graduated colors require complex calculations to determine the color values for each feature. When working with large datasets, these calculations can be time-consuming and may lead to performance issues.
Data type limitations: Line feature classes may not support all data types, which can limit the use of graduated colors.
Software bugs: As with any software, bugs can occur, leading to issues with graduated colors.

Workarounds

While the issues with graduated colors in ArcGIS Pro 3.4.0 can be frustrating, there are several workarounds to help you achieve the desired visualization:

Use a different symbology: Consider using a different symbology, such as a unique value or a proportional symbol, which may be more efficient and effective for your data.
Split the data: If you have a large dataset, consider splitting it into smaller subsets to reduce the computational complexity.
Use a different software: If you're experiencing persistent issues with graduated colors in ArcGIS Pro, consider using a different software, such as ArcGIS Desktop or a third-party GIS software.
Contact Esri support: If none of the above workarounds help, contact Esri support for further assistance and guidance.

Best Practices

To avoid issues with graduated colors in ArcGIS Pro 3.4.0, follow these best practices:

Use a small dataset: When testing graduated colors, use a small dataset to ensure that the results are accurate and efficient.
Choose the right data type: Ensure that your data type is supported by ArcGIS Pro and that it's suitable for graduated colors.
Optimize your data: Ensure that your data is optimized for use with graduated colors, including removing unnecessary fields and simplifying complex data structures.
Monitor performance: Keep an eye on performance when using graduated colors, and be prepared to adjust your approach if issues arise.

Conclusion

While graduated colors can be a powerful tool in ArcGIS Pro, issues with line feature classes in ArcGIS Pro 3.4.0 can be frustrating. By understanding the causes of the issue and using workarounds, you can achieve the desired visualization and communicate insights to stakeholders effectively. Remember to follow best practices to avoid issues with graduated colors and to contact Esri support if you need further assistance.
