Ggtitle("Area of counties in North Carolina") + Nc = st_read(system.file("shape/nc.shp", package="sf"), quiet = TRUE) You can also change or even remove the light source, and pass any arguments to plot_gg() that you would plot to plot_3d(). Once open, the plot can be manipulated like any other rayshader plot–you can call render_camera() to programmatically change the camera position, render_snapshot() to save or output the current view, or even use render_depth() to render a slick depth of field effect (I wrote about depth of field and its use in 3D visualization in my previous blog post-check it out at some point). ![]() If both are passed, the "fill" aesthetic will be used unless the user specifies heighttype = "color". If the user instead passes only the "color" aesthetic, that will be chosen instead. Plot_gg(deathgg, multicore=TRUE,height=5,width=6,scale=500)įigure 2: Rayshader automatically detects that the user has passed the "fill" aesthetic to a ggplot geom, and uses that aesthetic to map to #D. Ggtitle("Death Probability vs Age and Year for the USA") + Geom_raster(aes(x=Year,y=age,fill=value)) + Meltdeath$age = as.numeric(meltdeath$variable) Meltdeath = reshape2::melt(death, id.vars = "Year") #Data from Social Security administration And this works with any ggplot that includes a color or fill aesthetic, no matter the complexity 2 Intended to work–if you find examples where it doesn’t, leave an issue on the Github issues page. All of the graphing is still driven by ggplot2-rayshader just takes those objects and maps them to 3D.įollow transform an existing ggplot2 object into 3D, you simply drop the object into the plot_gg() function–rayshader handles the dirty work of stripping out all non-data elements, remapping the data, ray tracing shadows, and plotting it in 3D 1 Utilizing the rgl package. I wanted a 3D plotting package that didn’t require teaching users a new workflow or complex 3D modeling software just to produce a 3D plot this feature is immediately accessible to anyone that already knows how to use ggplot2.Īnd due to this desire for simplicity and ease of use, this implementation of 3D graphing is not a new 3D grammar of graphics. My primary goal was not just to provide a hacked-together utility for generating these plots–I wanted to make the interface as user-friendly as possible. By default, rayshader provides an isometric view of the graph, but you can add perspective by setting the field of view (argument fov) to a positive value. Or, the user can twirl the graph around interactively, and take single snapshots with render_snapshot(). The user can create animations by moving the camera using rayshader's render_camera() function. Plot_gg(gg,multicore=TRUE,width=5,height=5,scale=250)įigure 1: Rayshader's 3D ggplots work with any plot with a fill or color, even when facetted. Stat_density_2d(aes(fill = stat(nlevel)), Try it out! (note: Mailing list subscribers, the package will be out on Tuesday-come back and try the code then!) remotes::install_github("tylermorganwall/rayshader") Note: Each visualization in this article is accompanied by the code used to create it (the code for the featured video above is at the end of the article)-once you install the latest version of rayshader from Github, you can run the code below and immediately start playing along with me. ![]() How does one go about creating a 3D ggplot? Do I have to learn a completely new interface to create 3D plots? And wait, isn't 3D plotting bad? Continue reading to find out! Specifically, this tool generates 3D visualizations by transforming the color or fill aesthetics already defined in a ggplot2 object into the third dimension, and then maps the original plot onto that 3D surface. Creating this feature was a logical extension of rayshader’s core competency–using elevation matrices to generate raytraced 3D maps of topographic data. As rayshader gracefully rotates into its second year, I’m happy to announce the release of a feature I've been teasing for a while: 3D ggplots! It's been a long time coming, but the wait was worth it-I promise. ![]()
