title: Coloring dots in scatterplot diagram by Axis Label value
body: <p>I have a dataset from which I have plotted a scatter diagram as shown in the image. I would like to color the dots based on the first column values, because they recur in the dataset, so that I can identify points corresponding to various column values.</p>
