Discovering scheme files
•
Several years ago, Rachel Jinks and I were
looking through our adopaths, as you do, and
stumbled across the base\style directory
•
Opened something like color-blue.style and saw
that it contains
. set rgb "0 0 255"
•
I set-to writing my own to match MRC’s branding
Discovering scheme files
•
Not yet content, we stumbled across
scheme-s2color.scheme
•
It was easy enough to read, so I started
tinkering…

To write your own scheme, start file with:
#include s2color
•
Inherits everything that you don’t change

Writing your own scheme
•
Work cautiously when writing a scheme
•
Nice effects on one plot type may have
unintended consequences on others
•
Build scheme with a primary plot but have a
battery of others to check against
•
Can spend a long time on a scheme then
suddenly realise you’ve broken something and
can’t get back
Why don’t many people know?

A lot of scheme-changing is about colour. I wrote a
brief how-to paper. Then realised:
doesn’t do colour
Why don’t many people know?
Finally
In the spirit of keeping Wishes and Grumbles to
time:
1.
Grumble:
The Stata Journal
doesn’t allow
colour
2.
Wish: That
The Stata Journal
would allow
colour
(and put my paper in the first issue)

Scheme scheme, plot plot: crafting graph schemes in Stata Tim Morris MRC Clinical Trials Unit at UCL 7 Sep 2017
By all means break the rules, and break them beautifully, deliberately and well. Robert Bringhurst The Elements of Typographic Style
Removing the typos Typography should honour the text data for its own sake always assuming that the text data is worth a typographer s trouble and it should honour and contribute to its own tradition: that of typography itself. Robert Bringhurst The Elements of Typographic Style

Discovering scheme files Several years ago, Rachel Jinks and I were looking through our adopaths, as you do, and stumbled across the base\style directory Opened something like color-blue.style and saw that it contains . set rgb "0 0 255" I set-to writing my own to match MRC s branding
Discovering scheme files Not yet content, we stumbled across scheme-s2color.scheme It was easy enough to read, so I started tinkering Within a few hours, had done all of the every-single-time changes so I had to do them No. More. Times.
Help: scheme entries At the time, I wasn t aware of the scheme entries help It s helpful Importantly: you don t have to write a full scheme file. Of Stata s base schemes, only s2color is full To write your own scheme, start file with: #include s2color Inherits everything that you don t change
Example: scheme-my.scheme (goes in adopath at personal\s) 15,000 #include s2color color background white anglestyle vertical_tick horizontal symbol p circle_hollow color plotregion_line none yesno draw_major_vgrid yes yesno extend_axes_full_low no yesno extend_axes_full_high no 10,000 Price 5,000 0 2,000 3,000 4,000 5,000 Weight (lbs.) Price Price

Why dont many people know? It s mostlybecause Vince didn t use a Ludacris lyric as his presentation title
Why dont many people know? A lot of scheme-changing is about colour. I wrote a brief how-to paper. Then realised: doesn t do colour
Finally In the spirit of keeping Wishes and Grumbles to time: 1. Grumble: The Stata Journaldoesn t allow colour 2. Wish: That The Stata Journal would allow colour (and put my paper in the first issue)
