Width of Image (in pixel)

Background Color
The color of the background of the image. Hence this color is used for the area behind and around the plot as well as behind potential axis and legends.
Plot Background Color
The color of the background of the plot. Hence this color is used for the empty space in a plot.
Plot Background Alpha
The transparency of the plot background can be modified using an additional alpha value. An alpha value of 1 does not change the background transparency. Decreasing the alpha value will increase the plot background transparency.
