data-visualization

I have an array similar to this: [{year: 1999, val: 5}, {year: 2002, val: 8}] and I would like to add an axis where I have one tick for each year value (something I can do with tickValues and tickFormat) but where the tick label is not only the year but has a custom format, so the result could be something like "1999: 5" for the first array element. To rephrase it: Where I'm now const xAxis = d3.axisTop(xScale) .tickValues(data.map(d => d.year); This is not ok because only the year is visualized on the label of the tick and I would like to use a custom format. Is this possible with d3? You

UPDATE: The jsfiddle example illustrates the problem: http://jsfiddle.net/T8SuH/ I am new to both D3js and JavaScript but comfortable with Java. I have a large CSV dataset from a bike-sharing system organized as follows: event_id, station_id, timestamp, number_of_bikes, number_of_empty_docks To reduce file size, my data file contains only new events for individual stations. Therefore timestamps of different stations are neither in regular time intervals nor they coincide. For example consecutive entries might look like this: 31044955, 08, 2012-05-01 00:00:00, 9, 6 31044965, 23, 2012-05-01 00

This question was migrated from Cross Validated because it can be answered on Stack Overflow. Migrated 6 years ago . Is there a way to present symbols (e.g. greek letters, symbols or underscore/upperscore letters) as labels in a forest plot of an rma() object generated by the forest() function of the metafor package? Here is a nonsense example but it hopefully illustrates the underlying idea: library(metafor) data(dat.bcg) labs <- paste(dat.bcg$author, dat.bcg$year) ## Replace the first label with a greek letter, a superscript and a subscript labs[1] <- expression(beta[123]^123) res <- rma(ai

I am building a network graph using vis.js The problem is, how do I make all the images the same size ? (see live example here --> comparison of wordpress & drupal ) here's the graph code: var nodes = []; nodes.push({ id: 7, shape: 'image', image: '/static/windows8_icons/PNG/Industry/circuit/circuit-26.png', label: 'sharepoint', widthMin: 20, widthMax: 20 }); edges.push({ from: 1, to: 7, length: 100 }); var data = { nodes: nodes, edges: edges }; var options = { smoothCurves: false, stabilize: false, nodes: { shape: 'image', radius: 24, fontSize: 18, widthMin: 20, widthMax: 20 }, edges: { width

I have a for loop which produces 60 plots. I would like to save all this plots in only one file. If I set par(mfrow=c(10,6)) it says : Error in plot.new() : figure margins too large What can I do? My code is as follows: pdf(file="figure.pdf") par(mfrow=c(10,6)) for(i in 1:60){ x=rnorm(100) y=rnorm(100) plot(x,y) } dev.off() MrGumble Your default plot, as stated in the loop, does not use the space very effectively. If you look at just a single plot, you can see it has large margins, both between axis and edge and plot area and axis text. Effectively, there is a lot of space-hogging. Secondly,
