Values

Control	Description
Horizontal scale	Number of samples per unit of the x-axis. By unit of the x-axis the space is meant between two vertical lines of the background grid.
Buffer size	Number of samples to acquire. When you open the option tab, after having dragged-in all the variables you want to watch, you can read a default number in this field, representing the maximum number of samples you can collect for each variable. You can therefore type a number which is less or equal to the default one.

TracksThis tab allows you to define some graphic properties of the plot of each variable. To select a variable, click its name in the Track list column.

Control	Description
Unit	Unit of measurement, printed in the table of the Variables window.
Value/div	Δ value per unit of the y-axis. By unit of the y-axis is meant the space between two horizontal lines of the background grid.
Hide	Check this flag to hide selected track on the graph.

Push Apply to make your changes effective, or push OK to apply your changes and to close the options tab.User-defined ConditionIf you define a condition by using this control, the sampling process does not start until that condition is satisfied. Note that, unlike trigger windows, once data acquisition begins, samples are taken every time the window manager is triggered, regardless of the user condition being still true or not.After you enter a condition, the control displays its simplified expression.
