Is this what you are looking for:

*------------------ begin example -----------------
sysuse auto, clear

// put variables on the same scale
sum price, meanonly
replace price = (price - r(min)) /(r(max) - r(min))

sum mpg , meanonly
replace mpg = (mpg - r(min)) / (r(max)- r(min))

gen x1 = 1
gen x2 = 2

// create the graph
twoway pcscatter price x1 mpg x2 || ///
       pcspike price x1 mpg x2,     ///
       xlab(1 "price" 2 "mpg")

// However, in this case I would prefer
twoway scatter price mpg
*------------------ end example ----------------------

Hope this helps,
