Hei Humaria,
I am not aware of a GUI tool for that, sorry. But you have the full power of R
(https://cran.r-project.org/) at your fingertips:
In your GRASS console start R and then
# Load GRASS library
library("rgrass7")
# Fetch attributes
attributes <- execGRASS("v.db.select", map=’yourvectormap’, separator=’,’)
# Parse the result
con <- textConnection(attributes)
data <- read.csv(con, header=TRUE)
str(data)
#Make your plot
plot(value1 ~ value2, data=data)

Subject: [GRASS-user] scatterplot: vector/point data
Hi All,
Is there any GRASS command available to draw a scatter plot from the vector
(point) attribute table. There are 3 columns in the attribute table (cat,
value1, value2). I need to draw a scatter plot (value1 vs value2) in GRASS.
Thanks
