The number of values in the values array.
An array of HI_stVALUE structures.
The X value of the data pairs is transformed as follows:
x' = x * xscale + xoffset
The Y value of the data pairs is transformed as follows:
y' = y * yscale + yoffset
This function performs an offset and scaling transformation on a binary buffer of X-Y data pairs. The buffer is modified in place (i.e., a new buffer is not created, and the old values cannot be recovered). This function can be used to adjust data for graphing.
This function corresponds to the Cascade Historian hist_scale_buffer dynamic library function.
