Each plot gets updated with the same data. Im having issues, however, as it appears the indices argument does not apply to the correct trace in a subplot.
#Subplot in r update#
Create a common legend for these subplots and place it to the right of the subplots. 1 Good afternoon, Im attempting to use the plotly::plotlyProxyInvoke () function to update the data in a single plot of a subplot. This is the point at which, if this were a textbook, I would ask you to “Create a 2 row 1 column plot in R using the layout command. The plot, after much adventure, looks like this:
#Subplot in r manual#
Png ( "subplot9.png", height = 4, width = 8, units = "in", res = 300 ) layout ( matrix ( c ( 1, 2, 3, 4, 4, 4 ), ncol = 3, byrow = TRUE ), heights = c ( 0.9, 0.1 ), widths = c ( 0.1, 0.45, 0.45 )) par ( mar = c ( 0, 0, 0, 0 )) # Make the margins 0 for y label plot ( 1, type = "n", axes = FALSE, xlab = "", ylab = "" ) # Create empty plot text ( 1, 1, labels = "Y", srt = 90 ) # Create y label par ( mar = c ( 4.0, 0.5, 0.5, 0.5 )) # Make the margins non-zero for plots plot ( x, y, xlab = "X1", ylab = "", col = c1, pch = 16 ) plot ( x, y, xlab = "X2", ylab = "", yaxt = "none", col = c2, pch = 16 ) par ( mar = c ( 0, 0, 0, 0 )) # Make the margins 0 for legend plot ( 1, type = "n", axes = FALSE, xlab = "", ylab = "" ) # Create empty plot legend ( x = 0.93, y = 1.25, c ( "Blue Points", "Orange Points" ), horiz = TRUE, pch = c ( 16, 16 ), col = c ( c1, c2 )) # Manual placement of legend dev.off ()
The legend will have to be manually placed. (Note that once altered, the margin values stay the same until they are altered again). The margins also have to be altered for the y label, the plots and the legend. The second and third parts will hold the plots. In the top row, the first part in the layout will hold the y label. The new layout should have 2 rows, but 3 columns. Some things to keep in mind while doing this: There are probably other ways to address this gap, but the solution that worked for me is creating a new layout to hold the common y axis label. You would think “Yes, that’s it! It’s done!”. Png ( "subplot8.png", height = 4, width = 8, units = "in", res = 300 ) layout ( matrix ( c ( 1, 2, 3, 3 ), ncol = 2, byrow = TRUE ), heights = c ( 0.9, 0.1 )) plot ( x, y, xlab = "X1", ylab = "Y", col = c1, pch = 16 ) plot ( x, y, xlab = "X2", ylab = "", yaxt = "none", col = c2, pch = 16 ) par ( mar = c ( 0, 0, 0, 0 )) # Make the margins 0 plot ( 1, type = "n", axes = FALSE, xlab = "", ylab = "" ) # Create empty plot legend ( "top", c ( "Blue Points", "Orange Points" ), horiz = TRUE, pch = c ( 16, 16 ), col = c ( c1, c2 )) dev.off () Then it makes sense to remove the y axis tick marks and the associated tick labels, we do this with the following snippet: Now suppose that the two plots share the same units on the y axis and also similar ranges of the data. The above command creates an empty plot, and the legend function can be called after this. Creating a legend is necessarily preceded by creating a plot in the first place. plot(1, type = "n", axes=FALSE, xlab="", ylab="") – This creates an empty plot. par(mar=c(0,0,0,0)) – The reason for the first part is that by default, the plot margins tend to be quite big. For two columns, this is done as follows : png('subplot1.png',height4,width8,units'in',res300)par(mfrowc(1,2)) For one row, two columnsplot(x,y,xlab'X1',ylab'Y1',colc1,pch16)plot(x,y,xlab'X2',ylab'Y2',colc2,pch16)dev. With grid. Basic subplots in R The easiest subplot is using par. Library ( plotly ) # read in Walmart data df % add_lines ( y = fit, showlegend = FALSE, color = 'black' ) fig2 % layout ( showlegend = FALSE, xaxis = list ( side = "right", showgrid = FALSE ), yaxis = list ( showgrid = FALSE )) # second plot - scattergeo map g % add_markers ( text = ~ OPENDATE, showlegend = FALSE, marker = list ( color = ~ YEAR, showscale = FALSE ), hoverinfo = "text" ) fig3 % layout ( geo = g, showlegend = FALSE ) # third plot - 3D mesh #devtools::install_github("hypertidy/anglr") library ( anglr ) library ( maptools ) data ( wrld_simpl ) map1 % layout ( title = "Walmart Store Openings by Year", xaxis = list ( domain = list ( x = c ( 0, 0.5 ), y = c ( 0, 0.5 ))), scene = list ( domain = list ( x = c ( 0.5, 1 ), y = c ( 0, 0.5 ))), xaxis2 = list ( domain = list ( x = c ( 0.5, 1 ), y = c ( 0.Png ( "subplot7.png", height = 4, width = 8, units = "in", res = 300 ) layout ( matrix ( c ( 1, 2, 3, 3 ), ncol = 2, byrow = TRUE ), heights = c ( 0.9, 0.1 )) plot ( x, y, xlab = "X1", ylab = "Y1", col = c1, pch = 16 ) plot ( x, y, xlab = "X2", ylab = "Y2", col = c2, pch = 16 ) par ( mar = c ( 0, 0, 0, 0 )) # Make the margins 0 plot ( 1, type = "n", axes = F, xlab = "", ylab = "" ) # Create empty plot legend ( "top", c ( "Blue Points", "Orange Points" ), horiz = TRUE, pch = c ( 16, 16 ), col = c ( c1, c2 )) dev.off () The easiest approach to assemble multiple plots on a page is to use the grid.arrange () function from the gridExtra package in fact, that’s what we used for the previous figure.
