Editorial line chart with a callout and end labels
Time series charts in CanvasXpress show how values change over calendar time: annual, monthly and daily series as lines, step lines, areas, columns and small multiples, with confidence bands, projections, shaded periods, event callouts, dual axes and direct end labels. These examples recreate editorial chart idioms (the Datawrapper reference set) with synthetic data and publication-style themes; every one of them is an ordinary Scatter2D, Line, Area, AreaLine, Bar, BarLine or Stacked configuration, so the same options apply to your own dated data.
