Lines 68 to 80 in 1d0acf0

	function toLog(v, clip) {
	if(v > 0) return Math.log(v) / Math.LN10;
	else if(v <= 0 && clip && ax.range && ax.range.length === 2) {
	// clip NaN (ie past negative infinity) to LOG_CLIP axis
	// length past the negative edge
	var r0 = ax.range[0];
	var r1 = ax.range[1];
	return 0.5 * (r0 + r1 - 2 * LOG_CLIP * Math.abs(r0 - r1));
	}
	else return BADNUM;
	}
