void xlog
(xori, xmax, yformat, yori, yste, ymax) |
LOGPLT.C |
Level 2 |

float
xori |
The value of x at the left-hand end of the x
axis. |

float
xmax |
The value of x at the right-hand end of the x axis. |

char
*yformat |
The format which will be used for the y axis labels. Use %e,
%f, or %g
formats ("%-1.0f" for integer labels), enclosed in double quotes. |

float
yori |
The value of y at the bottom of the y axis. |

float
ystep |
The change in y between each two tick marks on the y
axis. |

float
ymax |
he value of y at the top of the y axis. |

xlog() is used to plot data with a logarithmic x axis
and linear y axis. It may be called before the datum points are
generated if the scales are known in advance. For a self-scaling version
of this function, see xlgscle(). xori
and xmax need not be even decades but they should have only one
significant figure (e.g., 2., .03, 500., ...). |
