I need to plot a number of bar charts as part of a shiny app. I am using ploty ly
x and y values are both numeric x being consecutive integer values. there are often missing values in the data I wish to plot - each plot needs to have a fixed x range. When there are more than a few missing values the bars for the remaining values are being plotted much wider spanning several x values ( see example 2) curiously when there is a single remaining value the bar width is correct (example 3) how can I maintain a constant bar width regardless of number of missing values? I cannot find a bar-width setting. df<-data.frame(x=1:20,y=rnorm(20)^2) #twenty bars each centred above a single x value: df%>%plot_ly( x = ~ x, y = ~ y, type = "bar")%>% layout(xaxis = list(range = c(0,20)), title = "example 1") # this produces wide bars first one spread x= 0-6 second x= 8-14 # expected two column same width as in example 1 centred above x=3 and x=11 df[c(3,11),]%>%plot_ly( x = ~ x, y = ~ y, type = "bar")%>% layout(xaxis = list(range = c(0,20)), title = "example 2 column width expands across multiple x values") # when only a single bar is present it is again the correct width - in this case centred above x=3 df[3,]%>%plot_ly( x = ~ x, y = ~ y, type = "bar")%>% layout(xaxis = list(range = c(0,20)), title = "example 3 correct columns again") [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
