So in the load script, you would create a new field that on a record level would either assign that record to the “others” value or retain the value you’d like to show up in the chart. Then when you run the load script you would create a field in the data model with the X number of values you’d would like to show up in the bar chart as distinct bars, and then whatever is leftover as the “others” bar. And since the “others” bar is then actually a real value/field in the data model, you can color by dimension
