I'm having difficulty getting plot to use the x-axis data with a bar-type plot.
Data being plotted:
dpn,:dpq NB. x-axis values ,: y-axis values
1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35
205 202 298 101 54 119 105 40 15 16 2 15 33 3 5 11 1 1
All the following plots work as I'd expect:
plot dpn;dpq
'type line' plot dpn;dpq NB. same as above
'type stick ' plot dpn;dpq
'type point' plot dpn;dpq NB. not readable, but accurate
The following does not use x-axis values supplied:
'type bar' plot dpn;dpq
I get bars numbered one through eighteen, rather than odd numbers 1 through 35.
Do I have to set these values manually for bar charts? If so, is that
difference documented?
Definition of the lists is:
NB. dp is list of distances between consecutive odd primes under 10000
dp=: <:}.}.}:+/"1(i.1229) =/ _1 p:i. 9999
dpq=: +/"1(~.dp) =/ dp NB. frequency of distance between primes
dpn=: /:~~.dp NB. nub of distance between primes
NB. (this is the first {:$dpq odd numbers, in this case)
