KDATA_STDDEV_ADD(3) Library Functions Manual KDATA_STDDEV_ADD(3) NAME kdata_stddev_attach -- attach source for standard deviation data plot- ting LIBRARY library "libkplot" SYNOPSIS #include <cairo.h> #include <kplot.h> int kdata_stddev_attach(struct kdata *dst, struct kdata *source); DESCRIPTION The kdata_stddev_attach function attaches a data source source to a standard deviation data source dst allocated with kdata_stddev_alloc(3). The internal buffers will be increased, if nec- essary, to the size of the new buffer. If the buffer is increased, the standard deviation values of the new buckets are set to zero. The x- values of the new pairs are set to the new source's x-values. Passing NULL as source will simply return. RETURN VALUES kdata_stddev_attach returns 0 if memory allocation failed or if dst was not allocated with kdata_stddev_alloc(3). SEE ALSO kdata_stddev_alloc(3), kplot(3) Donald E. Knuth, The Art of Computer Programming: Seminumerical Algorithms, 3rd Edition, Addison-Wesley, Volume 2, 232, Boston, 1998. CAVEATS If you attach multiple sources with different x-values, the standard deviation x-values will be inconsistent. FreeBSD ports 15.quarterly January 16, 2015 KDATA_STDDEV_ADD(3)
