How to Change Y Axis Limits in Decimal Points in R

How to change y axis limits in decimal points in R?

Set the limit of y and xpd = FALSE.

• FALSE : all plotting is clipped to the plot region
• TRUE : all plotting is clipped to the figure region
• NA : all plotting is clipped to the device region

library(RColorBrewer)
color <- brewer.pal(3, "Set1")[2:1]
plot.new()
plot.window(xlim = c(0, 10), ylim = c(94, 97.5), yaxs = "i")
abline(h = seq(94, 97.5, 0.5), col = 8)
barplot(as.matrix(mydata), beside = T, col = color,
        border = NA, legend.text = c("X1",   "X2"),
        args.legend = list(x = 'topright', bty = "n"), xpd = F, add = T)

How do I change the number of decimal places on axis labels in ggplot2?

From the help for ?scale_y_continuous, the argument 'labels' can be a function:

labels One of:

• NULL for no labels

• waiver() for the default labels computed by the transformation object

• A character vector giving labels (must be same length as breaks)

• A function that takes the breaks as input and returns labels as output

We will use the last option, a function that takes breaks as an argument and returns a number with 2 decimal places.

#Our transformation function
scaleFUN <- function(x) sprintf("%.2f", x)

#Plot
library(ggplot2)
p <- ggplot(mpg, aes(displ, cty)) + geom_point()
p <- p + facet_grid(. ~ cyl)
p + scale_y_continuous(labels=scaleFUN)

How to set decimal places at y-axis?

Could solve it, changing the code to

 ly_tcc <- plot_ly(PU29_Data_Zwischenstand_median[grepl("turbidity_feed",PU29_Data_Zwischenstand_median$parameter),],x= ~datetime,y= ~value,height=900,type="scatter",mode="lines+markers",
                          marker=list(size=2,color="blue"),line=list(color=alpha("blue",0.2))) %>%
                   layout(xaxis=list(title="Datum",tickformat="%Y-%m-%d"),
                          yaxis=list(title="turbidity feed",labels = fmt_dcimals(3)),
                          showlegend=F)

Is there a simple way to change the plot axis decimal indicator from point to comma in base R?

You can use options(OutDec = ",").

plot(data.frame(a=c(0.5,1,1.5,2,2.5,3,3.5,4),
                b=c(0.01,0.02,0.03,0.04,0.05,0.06,0.07,0.08)))

R how to control decimal digits for zero on axis labels?

We can use the axis function, and control the final display using the at and labels arguments.

plot(sin, -pi, 2*pi, yaxt = 'n') # make sure to specify yaxt = 'n'
axis(side = 2, at = c(-1, -.5, 0, .5, 1), labels = c('-1', '-0.5', '0', '0.5', '1'))

R: How to stop rounding percentages to 0 decimal places on plotly chart?

Using tickformat = ".2%" would solve (1. and 2.) in your case.

Explicitly defining tickvals (e.g. tickvals = seq(.02,.06, .01)) would answer (3.).

See https://plotly.com/r/reference/#Layout_and_layout_style_objects for more parameters.

Briefly, you could try:

  layout(
    yaxis = list(
      tickformat = ".1%",
      tickvals = seq(.02,.06, .005)
    ))

for example, or modify to your liking.

Scaling axis with different decimal places in ggplot

Just set the labels= as well. You can put whatever value you want there.

scale_x_continuous("", 
  limits = c(0.1, 10), 
  breaks = c( .1, .2, .4,.67, .8, 1, 1.25, 1.5, 2.5, 5, 10),
  labels = c( ".1", ".2", ".4" , ".67", ".8", "1", "1.25", "1.5", "2.5", "5", "10"),
)
