Displayr

Currently, data labels in Displayr support automatic contrast-aware font coloring via data.label.font.autocolor , which ensures readability by dynamically adjusting text color based on the background. However, annotations (via annotation.list and overlay.annotation.list in CChart() ) only support a fixed color parameter. This creates behavioral inconsistencies and can lead to readability issues when annotations are placed over varying chart colors. Requested enhancement: Introduce support for automatically coloring annotations, with functionality equivalent to that of data labels. This could include: A parameter such as: - annotation.font.autocolor = TRUE Or default behavior where annotation text automatically adjusts for contrast when no explicit color is set Benefits: Improved readability and accessibility Consistency between annotations and data labels Reduced need for manual formatting when chart palettes change Better support for dynamic / template-driven reporting Example use case: In charts where data labels automatically switch between light/dark text depending on fill color, annotations currently remain fixed (e.g., always black), making them hard to read on darker backgrounds. Matching this behavior would resolve the issue. Technical context: Annotations are currently defined via: ```r annotation.list = list( list(type = ..., data = ..., color = ...) )

I would like the ability to manually delete significance testing results for specific cells in charts where there is no data in one of the waves.

We are creating a dashboard and would like to swap data labels with images in custom charts, specifically in the Net Promoter Score vs. Key Competitor chart. This would allow logos to move as scatter plot points move, enhancing the visual representation of our data.

I would like to label individual data points in a scatterplot over time with specific identifiers such as month or year. This feature would enhance the clarity of data representation over time, which is currently unsupported.

When adding annotations to a data label and that annotation is based on a value in the data, e.g., Column n, then the value is included in the annotation without the ability to not show the value at all. E.g., I might get an annotation that's "19.00 " but all I really want is the " "

Currently, in bar and column charts, I cannot position the data label inside the bar either at the top, middle, or bottom; only outside.

Currently, scatterplots do not support hover text customization and the workaround for other visualizations does not work for them. This feature would add the ability for users to customize what is shown in the hover text using UI controls, rather than modifying code.

In this case, a user has two Y-axis inputs that have the same labels. The repeated labels make the scatterplot look messy and are redundant. Add functionality where a label could point to two different data points in the scatterplot.

I would like to have the option to display data labels at the end of a Time Series Visualization. Currently, the time series visualization doesn't support data labels at all. This feature would enhance the clarity of the data presentation by allowing viewers to see the data labels directly on the visualization, rather than having to hover over data points to view values in the legend.

When it comes to adding labels of any kind to the geographic map, you can only do this by adapting the process outlined in this help article: https://help.displayr.com/hc/en-us/articles/4411286467471-How-to-Label-a-Geographic-Map . Basically, it overlays another layer of geographic information and uses the latitude and longitude you specify to position the labels on the map.
