Apply Filter To A Chart?

I might use the filter as a selection from a combobox, or I might honestly wish to create 15 separate charts.

I have a spreadsheet. Three columns out of maybe six in immediate interest: Date, Name and score.

In "name" I have about 15 different students. I wish to create a chart that will extract the data for one of them which I would select - on the vertical ("y") axis have the scores (from "score") which range in whole numbers from 1 to 9, and on the horizontal ("x") axis show the dates (from "Date") of each score.

Complicating my thinking is the fact that a date can have more than one score, but seldom more than three.

I would then want to add a trend line through the graph, which, if I recall, is fairly easy to do.

I am wondering if I might at some point need to control the length of history, for though now I am working with about three months and over that period of time no one has more than 18 total scores.
