If the graph is absolute then the displayed scaling of vertical axis is
valid for all curves, otherwise, the scaling is valid only for the labelled
base curve. Its parameters are written in the separate window located
in the left bottom corner of the graph main window. In the relative
mode all curves are scaled to share the vertical range with the base
curve. The vertical range of each curve can be changed in the legend
context menu. This range is valid only for the current graph. It is not
the same as the range defined in the Linguistic Variable Editor. Only
the default range is the same. The main graph window consists of
three parts (see History Graph), the Real graph window, the Legend
and the Base Variable Property.
• Real graph window - This window is located on the right side of
the graph main window, and it cannot be hidden. Measured
historical samples are plotted here. Adjacent data points are
linked by a line, no interpolation is applied. The number of
curves displayed is limited to 1000. The grid of both axes is set
automatically. Range of displayed data can be changed by
zooming in and out. The units of the horizontal axis are written
below the line. The units of vertical range are not displayed as
the plotted variables might not share the same units. Right-click
the legend to display the graph context menu (see History
Graph Context Menu). You can change the graph size, or view
the graph property window.
• Legend – This is located on the left top corner of the main graph
window. You can hide it by using a graph toolbar button. The
legend lists the displayed curves. Related text items and curves
share the same color. If the curves overlap, the color of the first
related item from the legend is applied. Use a drag-and-drop
operation to reorder the list of items.
The first item in the list is a base curve taken as a reference if the
graph is relative in scale. Right-click the legend, and the legend
context menu appears (see History Graph Legend Context
Menu). From this menu, you can change the color or the vertical
range tick marks related to a curve.
