Multiple color line charts are single-series charts with a line passing through and connecting individual scatter points at (x, y) cartesian coordinates. The line chart is represented by all continuous segments joining these points. Unlike the regular line chart, multi-color line charts have each segment using a different series color. The points are eventually highlighted - with markers - when the mouse moves over them.
Our US Sales demo charts show a line joining the points at the intersection of each year value between 2000 and 2017 and the number of products sold in US in that year. Each segment gets a different color. The horizontal X baseline appears here as a category axis, with regular intervals for each year value. Line charts use also often a linear baseline, with X values distributed at random intervals.
