SPARKLINE draws a small chart inside a cell. It is useful beside a row of figures when you need to scan a pattern without opening a separate chart. The first argument is the data range. The optional second argument is a two-column list of settings and values.
For example, {"charttype","column";"color","#188038"} selects columns and their color. Commas separate the two columns; semicolons start another option row. Setting names and text values need quotes. Numeric settings such as max use numbers or cell references.
The default is a line. Column charts show the size of each value, bar charts can show progress toward a maximum, and winloss charts show only whether each value is positive or negative. Automatic scales can make very different rows look similar. Use common ymin and ymax settings when the rows need a fair visual comparison.
