The Rescaling Menu

The rescaling menu contains two groups of scaling options, one group for the Y axis and one for the X axis:

Y Axis Rescaling

Selection	Function
Linear	Invokes linear Y axis scaling.
Log	Displays the Y axis using logarithmic scaling.
Currency	Displays the Y axis in the currency (i.e., dollars) of the option chart’s underlying instrument.
Points	Displays the Y axis in the points of the option chart’s underlying instrument.
	Scrolls the chart up the Y axis.
	Expands the Y axis.
	Scrolls the chart down the Y axis.
	Compresses the Y axis.
Auto	Returns the Y axis to default scaling.

X Axis Rescaling

Selection	Function
Linear	Invokes linear X axis scaling.
Log	Displays the X axis using logarithmic scaling.
	Scrolls the chart left on the X axis.
	Scrolls the chart right on the X axis.
	Expands the X axis.
	Compresses the X axis.
More	Increases the degree of accuracy by inserting more calculation points per grid line. The more points per grid line, the more time it takes to calculate strategy lines.
Less	Decreases the degree of accuracy by decreasing the number of calculation points per grid line. The less points per grid line, the less time it takes to calculate strategy lines.
Auto	Restores the X axis to default scaling.

Color Shifts in the X and Y Axes

Some selections in the Rescaling menu causes the X and Y axis scale numbers to change color. The following table summarizes these color shifts.

Axis	Color	Indication
X	Orange	Default
X	Light Blue	Scale has been shifted, expanded, or compressed, and is locked.
Y	Orange	Default (currency)
Y	Light Red	Y axis has been set to points.
Y	Light Blue	Scale shows currency and has been shifted, expanded, or compressed and is locked.
Y	Dark Blue	Scale shows points and has been shifted, expanded, or compressed and is locked.
