Datasets: Chart legend
The screenshot from https://sandbox.genesys-pgr.org/datasets/ecfca747-36bd-478e-82f5-fd2d70911306/overview
shows how the labels overflow the available space:
The better display would use a Chart legend that renders the displayed codes below the chart like we do for scale descriptors:
Summary
The chart uses codes on X axis and they are displayed without slanting (just normal), and then below the chart we display the coding table for scale and for coded descriptors.
And while we're at it
Please relabel "Count" on Y axis to "Accessions".
