jpeg '<filename>' [at <x>, <y>] [rotate <angle>] [width <width>] [height <height>]
The jpeg command places a jpeg format bitmap image into the current plot. The at modifier can be used to specify the position of the bottom-left corner of the image, otherwise it is placed at the origin. If the rotate modifier is used the image is rotated by the specified angle counter-clockwise. Either the width or height modifier should be specified, followed by the width or height respectively in cm that the resulting image should be. The jpeg command is perhaps most useful in multiplot mode, where images can be combined with plots, text labels, etc.
