void ylog(xformat, xori, xste, xmax, yori, ymax) |
LOGPLT.C |
Level 2 |

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

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

float xstep |
The change in x between each two tick marks on the x axis. |

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

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

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

ylog() is used to plot data with a logarithmic y axis
and linear x 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 ylgscle(). yori
and ymax need not be even decades but they should have only one
significant figure (e.g., 2., .03, 500., ...). |
