General Plot Options

Type of Image
The type of the created image can either be png or svg. PNGs are mostly smaller, SVGs provide details about plot and the possibility to be changed individually.
Title of Graph
The title of the graph shown above the generated image. If the title is not activated, no title will be shown.
Width of Image (in pixel)
The width of the generated image, not the plot width.
Height of Image (in pixel)
The height of the generated image, not the plot height.
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.
Scale Font Size
Factor changes the font sizes within the JFreeChart view. A value greater the 1 increases all view fonts, a value between 0 and 1 decrease them.
