I have a plotly chart showing a simple scatterplot, I'd just like to add more info to the label on hover.
For simplicity, lets say I have columns for Date, Value, and Description. I'm plotting Date and Value as my x and y, but I'd like to have the Description display on hover ONLY (i.e. not using it as a splitter, axis, or plotted serie).
It was easy enough to customize the template to display hardcoded dummy "descriptions", but my C# isn't great and I just can't seem to actually access the Description column data without plotting it.

So is there a way to access a column in the model that isn't explicitly a serie and get it's values into something resembling the ChartYSerieValues string? Or alternatively, to make it a serie but not plot it?

I made a report to handle your requirement...just to display the last name in the chart.
based on https://plotly.com/javas...ver-text-and-formatting/

In a custom template of the Plotly View, create a text values string that will be the list of label descriptions:
                        var textValues = "";
                        foreach (var xv in page.ChartXLabels.Split(',')) {
                            //find the row in the ResultTable
                            var desc = "";
                            foreach (System.Data.DataRow dr in reportModel.ResultTable.Rows) {
                                if (dr["C0"].ToString() == xv.Replace("'","")) {
                                    desc = dr["C1"].ToString();
                            if (textValues.Length != 0)  { textValues += ","; }
                            textValues += Helper.QuoteSingle(System.Web.HttpUtility.JavaScriptStringEncode(desc));

Note that C0 or C1 are the columns defined in the model (View SQL from the model).

Then inject it in the chart:
                            marker: { color: @Raw(color) },
                            text: [@Raw(textValues)]
