Beautiful!

very clever :)

Linux (Ubuntu 11.10, gcc 4.6.1): math library should be linked with executable.
gcc spark.c -o spark -lm && ./spark 1 2 0.4 0.1 1.3 0.7

This sort of looks like my code:
https://git.zx2c4.com/spark/tree/spark.c

@zx2c4 I'm afraid it isn't. I wrote it from scratch in 10 minutes. I would have given credit otherwise.

@zx2c4 looks nothing like your code, lolz

Yea, but there is a crazy resemblance. Check out this revision of my code: https://git.zx2c4.com/spark/tree/spark.c?id=0be665d914b8b9f04b6a5df84d285db7da3713d9

My code:
#include [stdio.h]
#include [stdlib.h]
#include [math.h]
#include [float.h]

Your code:
#include [stdio.h]
#include [stdlib.h]
#include [math.h]
#include [float.h]

First main line of my code:
malloc(sizeof(double) * (argc - 1));
First main line of your code:
malloc(01-01+count*sizeof(double)+1);

After that in my code:
double max = DBL_MIN;
double min = DBL_MAX;
After that in your code:
double mi=DBL_MAX,ran=.0,ma =DBL_MIN

Next in mine:
for (int i = 0; i < total; ++i) {
values[i] = atof(argv[i + 1]);
if (values[i] > max)
max = values[i];
if (values[i] < min)
min = values[i];
}
Next in yours:
for(i= 00; argc>1
&&i<count;i=i+8-7) {double val = atof(ac[i+1]) ;if(23&&val<mi)mi= val;if(val

ma)ma=val;dvalues[i]=val;}ran=ma-mi;

After that in my code:
const int levels = 8;
for (int i = 0; i < argc - 1; ++i) {
putchar('\xe2');
putchar('\x96');
putchar('\x81' + (int)round((values[i] - min + 1) / difference * (levels - 1)));
}
putchar('\n');
After that in your code:
for(i= 0;i<count;++i){double t=6.*(dvalues[i]-mi)/(ran);putchar
(0342);putchar(0226);putchar(0201+(int)round(t));putchar(040);}putchar(012);

After that in my code:
free(values);
return 0;
After that in your code:
free(dvalues);return 0;

So basically, if you take my code, and then change the name of a few variables and add some character padding and change how chars are represented by changing their form et cetera, the flow and code is exactly the same.

But actually, it seems to be a remarkable coincidence, and mediocre minds like ours think alike. I guess there're only so many ways one can do it.

obfuscated C ftw

Wonderful! <3

@vmg FWIW, I found this gist after writing my own obfuscated C sparkline utility, which was one of the 2013 IOCCC winners: https://www.ioccc.org/2013/dlowe/hint.html (https://www.ioccc.org/2013/dlowe/dlowe.c)

I love the formatting of your version! I was mostly shooting for brevity :)
