X Scale This drop-down list can be used to select an X scale type. Options are:
  • Linear
    Standard linear scale, where X'=X.
  • Log10
    Base 10 logarithmic scale, where X'=log(X).
  • Probability
    Represents the inverse of a cumulative Gaussian distribution: X'=norminv(X/100). Plotting a cumulative Gaussian distribution produces a sigmoidally-shaped curve. This curve, when displayed on a probability scale, appears as a straight line. Since probabilities are expressed as percentages, all values must fall between 0 and 100. The probability scale range is 0.0001 to 99.999.
  • Probit
    Like the probability scale, a sigmoidally-shaped curve plots as a straight line. In this case, however, the scale is linear, and the increment between tick marks is exactly one standard deviation. The value "5" on the scale shows the mean, or 50% probability. "6" is one standard deviation away, etc.
  • Reciprocal
    Reciprocal scale, where X'=1/X.
  • Offset Reciprocal
    Offset reciprocal scale, where X'=1/(X+offset). Offset is defined as 273.14, where 273.14 is the absolute temperature for 0° C.
  • Logit
    Logit=ln(Y/(100-Y)). As with the probability and probit scales, a sigmoidally shaped curve plots as a straight line.
  • Natural Log
    ln, base e logarithmic scale.
  • Log2
    Base 10 logarithmic scale.
Y Scale This drop-down list can be used to change the Y scale type. The options in this drop-down list are the same as the ones in the X Scale drop-down list.
Bottom This branch can be used to modify the bottom X axis.
Axis
Specify whether to show the bottom axis.
Tick
This drop-down list is available only when the Axis check box is selected. It can be used to specify the display of ticks on the axis:
  • In & Out
    Show the ticks that point inward and also those that point outward.
  • In
    Show only the ticks that point inward.
  • Out
    Show only the ticks that point outward.
  • None
    Do not show any ticks.
Title
Specify whether to show the title of the bottom axis.
Tick Label
Specify whether to show the tick labels of the bottom axis.
Formula
Specify a formula to calculate a numeric vector which will be used as the tick labels of the axis. Note that the calculation will not affect the source data.
Left This branch can be used to modify the left Y axis. The options are the same as the ones in Bottom branch.
Top This branch can be used to modify the top X axis. The options are the same as the ones in Bottom branch.
Right This branch can be used to modify the right Y axis. The options are the same as the ones in Bottom branch.
