Data scientists have been releasing advanced graphical tools in R packages for many years. Unfortunately, individuals with no coding knowledge are unable to access such tools. One particularly well-used package, ggplot2, produces graphical outputs which scientists in many disciplines find useful for their data sets. Here, we release Spectrum Data Plotter, a web-based integration of standard ggplot2 features optimized for general scientific data plots. Spectrum Data Plotter is able to produce, overlaid or one-by-one, user-customized dot plots, average and standard deviation or error plots, boxplots, and violin plots. While options are not comprehensive to the ggplot2 library, many customizations including line type, color, transparency, and sizes are available to the user using simple text inputs, pull-down menus, or check boxes. Given the limitations of paid software, the intent is for users to be able to generate beautiful plots which fairly and wholly communicate users’ hard-earned data.
