Adjusting the Axes
The x-axis and y-axis of your graph determine the range of values that are visible. You can adjust their scale to best display your data.
If you already have some data and you want to automatically adjust the axes to it:
- Click the Scale to Fit toolbar button, or choose Scale to Fit Data from the View menu.
There are several ways to make an axis show a different range of values:
- Click a tick label (the number) near the end of the axis, and drag it toward the edge or toward the middle. The ticks get closer together or farther apart. You may need to do this more than once to get the range you want.
- Double-click the tick label on the edge of a graph, and type the number you want. Note that editing a tick label that’s not on the very edge of the graph just changes that label; it doesn’t change the axis range.
- Use the Axes inspector to type in precise axis ranges.
To move the axes without changing their scale, click and drag either axis.
You can control the location and visibility of axes, tick marks, and labels with the Axes inspector.
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.
