label of x-axis

[River Huang]

Dear All, I was asked this question (https://bbs.pinggu.org/thread-10348633-1-1.html). The data set and code (to be modified) is:

* Example generated by -dataex-. To install: ssc install dataex
clear
input double(stock mon d)
28 40 1
23 35 2
18 30 3
25 36 4
30 45 5
end

twoway connected stock d ||connected mon d,lp(dash) xscale(range(0.5 5.5))   ///
xlabel( 1 "25岁以下"  2 "25-34"  3 "35-45"  4 "45-50"  5 "50岁以上" ) xtitle("") scheme(s1mono)

The graph is

But the desired one is (with relocation of the label on the x-axis):

Please note particularly that the location of the x-axi, say 25-34. Thanks.

The x-axis is continuous, so in the same way that you can label "1" and "2", you can also label "1.5" and "13.3". Here is a way to achieve something similar to what is wanted.

* Example generated by -dataex-. To install: ssc install dataex
clear
input double(stock mon d)
28 40 1
23 35 2
18 30 3
25 36 4
30 45 5
end

twoway connected stock d ||connected mon d,lp(dash) xscale(range(0.5 5.5))   ///
xlabel( 1.5 "25岁以下"  2.5 "25-34"  3.5 "35-45"  4.5 "45-50"  5.5 "50岁以上", noticks ) xtick(#6, tposition(inside)) xtitle("") scheme(s1mono)

You can explicitly specify the position of the ticks, but specifying the number of ticks ensures an even distribution across the axis.

Dear Andrew, Thanks again for your help. Is it possible to put the circles/squares just above the labels as the second graph I posted? Thanks.

[Andrew Musau]

The markers are in the integer positions, so you just want to modify the position of the inner ticks. [0.5(1)5.5] will do it.

* Example generated by -dataex-. To install: ssc install dataex
clear
input double(stock mon d)
28 40 1
23 35 2
18 30 3
25 36 4
30 45 5
end

twoway connected stock d ||connected mon d,lp(dash) xscale(range(0.5 5.5))   ///
xlabel( 1 "25岁以下"  2 "25-34"  3 "35-45"  4 "45-50"  5 "50岁以上", noticks ) ///
xtick(0.5(1)5.5, tposition(inside)) xtitle("") scheme(s1mono)

Dear Andrew, This is great. Thanks again.
