The inclusion of a legend is crucial for interpreting chart data accurately and efficiently, allowing viewers to quickly grasp the nuances and relationships within the data. Employing chart legends in professional settings aids in the clear communication of information, supporting better decision-making based on visual data insights.

10 Notes of the Chart Legend

Once you have configured the legends, you may wonder if the previous configuration will remain when switching between chart types. You can refer to the following rules:

1. If the original chart was a custom chart:

• Switching chart types in Graphic Properties retains the legend configuration.

• Switching chart types in Chart Type above Graphic Properties does not retain the legend configuration.

2. If the original chart was a non-custom chart:

• Switching to a custom chart in Graphic Properties retains the legend configuration.

• Switching to another non-custom chart in Chart Type above Graphic Properties does not retain the legend configuration.

In summary, chart legends play a pivotal role in enhancing the readability and interpretability of data visualizations. They provide a crucial link between visual elements and their meanings, facilitating a deeper understanding and more effective communication of insights gleaned from the data. By enabling users to customize legends to fit specific needs and contexts, FineBI ensures that charts are not only informative but also tailored to enhance decision-making processes. The continual updates to legend functionalities underscore their importance in dynamic and data-driven environments.
