r - Problems plotting a variogram

Question

I'm trying to plot a variogram of a Spatial data frame I got but the axis in the plotted image are wrong, they don't allow all points to be plotted. The R-studio version I'm using is 1.3 in Ubuntu 20.

Here is the code:

library(sp)
library(gstat)
library(readxl)

exceldata=read_excel('my_path')

dfdata=data.frame(exceldata)  #data frame
xy=dfdata[1:2]      #coords. of dfdata
values=dfdata[3]   #values of dfdata
Spatial_data=SpatialPointsDataFrame(coords=xy, data=values)  #spatial df

Spatial_data$logAu=log10(Spatial_data$au)

ve=variogram(logAu~1, 
             Spatial_data,   
             cutoff=10000,  
             width=50)
plot(ve)

Here is an extract of the data frame (of a total of 150 elements).

However, the plot is this. I'm learning R and I don't know what do the "cutoff" and "width" mean. How can I get the entire plot without those cuts in the distance axis?

Besides, the dput command shows this info: img1 img2 img3
