Add padding to the x-axis in a twoway plot

[Aleksej Stevanovic]

Hi

I am struggling with adding padding to the x axis. I use the following code:

twoway ///
(rcap low95 high95 row, vert) /// code for 95% CI
(scatter proportion row if group ==1, mcolor(black)) /// dot for group 1
, /// legend at 6 o'clock position
xlabel(1 "Concentration" 2 "Progressive motile" 3 "Total sperm count" 4 "Motility (%)" 5 "Volume", angle(30) noticks) ///
/// note that the labels are 1.5, 4.5, etc so they are between rows 1&2, 4&5, etc.
/// also note that there is a space in between different rows by leaving out rows 3, 6, 9, and 12
ylabel(0 "0" -5 "-5" -10 "-10" -15 "-15" -20 " -20" -25 "-25", angle(0)) /// no 1.6 label
yline(0, lpattern(dash) lcolor(gs8)) ///
/// aspect (next line) is how tall or wide the figure is
aspect(0.7)

I get the following graph

I would like to add padding before the concentration because as you see it is very close to the y axis, and I would also like to add padding after volume, Any idea how to do that?

Also how do I remove the legend in the code?

Cheers

For your future posts, include a data example using the dataex command that reproduces the graph (refer to FAQ Advice #12). See highlighted:

twoway ///
(rcap low95 high95 row, vert) /// code for 95% CI
(scatter proportion row if group ==1, mcolor(black)) /// dot for group 1
, /// legend at 6 o'clock position
xlabel(1 "Concentration" 2 "Progressive motile" 3 "Total sperm count" 4 "Motility (%)" 5 "Volume", angle(30) noticks) ///
/// note that the labels are 1.5, 4.5, etc so they are between rows 1&2, 4&5, etc.
/// also note that there is a space in between different rows by leaving out rows 3, 6, 9, and 12
ylabel(0 "0" -5 "-5" -10 "-10" -15 "-15" -20 " -20" -25 "-25", angle(0)) /// no 1.6 label
yline(0, lpattern(dash) lcolor(gs8)) ///
xscale(range(0, 6)) ///
legend(off) ///
/// aspect (next line) is how tall or wide the figure is
aspect(0.7)

Hi

Thank you for you reply, it made absolutely no difference. The legend is still there and there and "command xscale is unrecognized"

Here is the data

clear
input byte(row group) double(proportion low95 high95)
1 1 -16.05 -12.16 -19.83
2 1 -22.81 -27.88 -17.94
3 1 -19.05 -23.21 -15.18
4 1   1.58   -.38   3.43
5 1  -1.97  -3.77   -.55
end

It works out on my side. Copy and paste the exact output.

You could also zap the x axis title with xtitle(“”)

Thank you for your reply. I got it to work but now there is too much space on each side,it looks unnatural

[Andrew Musau]

The range defines a continuous scale, so you should be able to manipulate the start and end points, e.g.,

xscale(range(0.5, 5.5))

[Nick Cox]

So try 0.5 to 5.5 as x range. Or exchange x and y axes (allowing horizontal text).
