Non-orthogonalityĪlthough our ideal in most software engineering is to have To make and set commands to implement them. Ugly or broken, but there is a straightforward mapping between changes you may want So the inital plot is one command, everybody thinks the defaults are If you want to layer components, like a regression line through a scatterplot You can find in the awkward interactive help system, or can't be modified so stop At the middle layer, every component either has a set command which At the top layer, start with a plot or splot command to generate Initial use and thus maps nicely to the SDVW, we have that unfashionable workhorse To give an example of a system that prefers ease of use over ease of They would both be, but our time on Earth is finite, and package authors have There's a neat mapping between the SDVW and ease of (initial) use: is theįocus on making the top layer or the middle layer fast and easy? In an ideal world, Same reason, the SDVW involves slightly different changes every time. Is a probability zero event that the defaults are exactly correct. No matter how stellar theĭefaults, your are plotting unique data, so it Is also often what is demanded by people new to the package, who wantĮase of use is about the middle layer. Something attractive out of the box, and is what is demanded by theĮxploratory workflow and the under-a-deadline workflow. Ease of (initial) useĮase of initial use is when the top-layer command quickly produces When working to a tight deadline for people who think ExcelĬharts look good, the workflow may be to call the top layer command and Workflow: add a top layer command to a script or call one from theĬommand line, try to learn something from the plot displayed, then throw The most common other workflow may be the exploratory It is easy to understand and implement: get theīasic plot up, then tick through every element that needs modification, Talk about a plot (`It's basically OK, but this one thing looks off'). To something more appropriate to the situation.

Then applying a series of middle-layer commands to adjust the defaults Starting with the one-line command from the top layer to generate a plot, Let the standard data viz workflow (SDVW) consist of Manipulate elements we commonly accept as part of a plot: axes, points, Middle layer Step past abstract drawing and To draw lines, paint dots, write text sideways. As with any effort towardĭevice-independence, every package author works out a set of primitives I think of all of these dataviz packages as three-layer systems:īottom layer In the end, we have to get dots on the canvas, be itĪ Mac/X/Windows/browser window, a png, a gif, an SVG,Ī LaTeX diagram, or ideally all of the above. Such a high hurdle to adoption that it would need regular exposure on the cover of Meanwhile, everybody wants to be able to type plot(height, weight) and get a plot.Ī system that doesn't have that capability of one-command plot generation would have Positions, color, transparency, a key or legend and its content. Scale (linear? log?), a grid (if any), the points themselves and their shape, size, On the basic scatterplot, you've got axis labels, major and minor tic marks, The short version of the plotting problem: so many elements, each of which needs to be To my character, this series will be largely conceptual and have no visuals. Next episode willīe entitled `D3: a travelogue', because I think D3 is worth extra attention. Solve them, and why being a tourist like this is such hard going. This is a post by a tourist about the problems these packages face and how they try to I've toyed with base R, ggplot2, Gnuplot, matplotlib, Bokeh, D3, some D3 add-ons I'veĪlready forgotten about, some packages I tried for five minutes and walked away from.
