|void xlgscle (nydiv, x, y, npts)||LOGPLT.C||Level 2|
|int nydiv||The number of y axis divisions.|
|float *x||The vector of x data.|
|float *y||The vector of y data.|
|int npts||The number of data points in the x and y vectors.|
|The self-scaling axis routine, xlgscle(), finds the correct
number of decades so that the logarithmic x axis can accommodate
the data. Labels on log axes are always placed at the decade markings.
Intermediate points are labeled depending on the spacing between divisions.
The y axis is linear.
