If you PRINT a VDEF value, you can also print the time associated with it by appending the string
-B<:strftime> to the format. Note that rrdtool uses the strftime function of your OSs C library. This means that

the conversion specifier may vary. Check the manual page if you are uncertain. The following is a list of
conversion specifiers usually supported across the board.

See B<LINE>, however the area between the x-axis and the line will
be filled.

+Similar to B<AREA>, except the area between the line and the x-axis will contain a gradient from color1 to color2.
+
+The I<height> parameter can create three different behaviors. If I<height> > 0, then the gradient is a fixed height, starting at the line going down. If I<height> < 0, then the gradient starts at fixed height above the x-axis, going down to the x-axis. If I<height> == 0, then the gradient goes from the line to x-axis.
+
+If not present, I<color2> defaults to #00000000 and I<height> defaults to 50.
