Scatter Plot (JFreeChart)

retrieved from the input data table. The size of the items is determined by the option: Item size.
For general settings of the generated
image, see the "General Plot Options" Tab.

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.
