Line Chart (JFreeChart)

Visualizer

Displays a line plot with JFreeChart. A line chart uses x,y data points and connects them by a line. Hiliting is not supported. For general settings of the generated image, see the "General Plot Options" Tab.

The second in-port provides the possibility to specify colors for the different lines/columns in the plot. Therefore append a Extract Column Header and Transpose node to the data table which should be plotted in this node. Afterwards use the Color Manager to append the colors based on the individual column names. The node automatically selects the column from the Color Manager and assigns the color values to the plotted columns.
