Create scatterplot with multiple variables

General
1

I am trying to create a scatter plot with two y-axis variables against an x-axis variable, and am having a challenging time. The code I created only shows a blank graph with the x and y axis labeled.

This is my code created;

data1
attach(data1)
plot(Average.length_cm, Female, main = "Size at maturity", xlab = "Total length (cm)", ylab = "% Maturity", pch=12)
plot(x=Average.length_cm,
     y=Female,
     xlab='Total length (cm)',
     ylab='% Maturity',
     main='Size at maturity', xlim=c(0,12),
     ylim=c(0,100))
plot(x=Average.length_cm,
     y=Female,
     xlab='Total lenght (cm)',
     ylab='% Maturity',
     main='Size at maturity', xlim=c(0,12),
     ylim=c(0,100),
     col='blue',
     col.axis='black')

plot(data1[data1$Gender=='F',]$Average.length_cm,
       data1[data1$Gender=='F',]$Female, xlab='Total length (cm)',
     ylab='% Maturity', main='Size at maturity',
       xlim=c(0,12), ylim=c(0,100), col='blue', col.axis='black',
       pch=8)
par(new=TRUE)

plot(data1[data1$Gender=='M',]$Average.length_cm,
       data1[data1$Gender=='M',]$Male, xlab='Total length (cm)', 
     ylab='% Maturity', main='Size at maturity',
       xlim=c(0,12), ylim=c(0,100), col='red', col.axis='black',
       pch=16)

Any advise?

Hello!

Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

Here, we do not know what data1 is.

Thank you!
