Interactive time series plots include multiple options for incorporating external data such as forecasts and events. Other static plots useful for time series data include an intuitive and generic scatter plotter, a boxplot generator suitable for multiple time series, and event study plotters for time series analysis around sets of dates.https://github.com/r-universe/derekholmes0/actions/runs/37654408007Wed, 07 Oct 2026 12:26:12 GMTFinanceGraphs0.9.22successhttps://derekholmes0.r-universe.devhttps://github.com/derekholmes0/financegraphsFinanceGraphs-customization.RmdFinanceGraphs-customization.htmlFinanceGraphs-Customization2026-03-02 22:04:042026-03-23 20:50:19Time-Series-dygraph.RmdTime-Series-dygraph.htmlTime-Series-dygraph2026-03-02 22:04:042026-03-23 20:50:19Time-Series-scatterplot.RmdTime-Series-scatterplot.htmlTime-Series-scatterplot2026-03-02 22:04:042026-03-10 15:21:47
