Zero is infinitely far away in logarithmic space, so the minimum and maximum values on a logarithmic axis must be values that are either both greater than zero or both less than zero. When switching from a linear axis to a logarithmic one, OmniGraphSketcher automatically updates the values to avoid creating parameters that are mathematical impossibilities.
When values are larger than 10,000,000 or smaller than 0.001, OmniGraphSketcher uses scientific notation. On logarithmic scales, simplified powers of ten are used when possible. (For example, 10^9.) You can edit these values and enter new data points with E notation. (For example, 1.23E45 or 6E-7.) To accommodate data sets that span many orders of magnitude, axes and data points support up to 13 significant digits and can hold values up to and including 10^300.
Lines in OmniGraphSketcher are drawn to connect two or more data points as smoothly as possible. The underlying data points are mapped accurately to linear or logarithmic space, however, intermediate points are not comparable. To accurately map a line's shape between linear and logarithmic axes, choose Interpolate Line from the Arrange menu to sample the line's x-values. Upon switching to a logarithmic axis, each part of the shape adjusts to logarithmic space.
