Plots the numeric columns of the input table as lines. All values are mapped to a single y coordinate. This may distort the visualization if the difference of the values in the columns is large.
Only columns with a valid domain are available in this view. Make sure that the predecessor node is executed or set the domain with the DomainCalculator node!
The data points may be selected by either dragging a rectangle with the mouse over the points or by clicking on points (if the dots are not displayed you won't see the selection or hilite since only data points can be selected or hilited). Hold control pressed for multiple selections. The selected datapoints may be hilited by either right-click to get the context menu or via the hilite menu in the menu bar.
Move the mouse over the data points to get detailed information about the data point (Row ID, the x and y values).
Column Selection: Choose the columns you want to have displayed as lines. If the visualization is distorted due to great differences between the columns the most distorting columns can be removed to scale the y axis correctly.
Legend: Since the colors of the lines do not depend on the colors of the rows (since not the rows, but the columns are displayed as lines) the colors are created automatically. Click "Change..." in the legend to change the color of the referring line.
Missing Values: Per default missing values will interrupt the line. Check "Interpolate" to linearly interpolate the missing values. Missing values at the beginning and at the end will not be interpolated.
