To set a specific tick mark interval, use the Extents/Intervals/Size command on the Options menu and:

1) | Select Specify Interval OR |

2) | Select Specify number and enter the number of intervals on each axis. Check Specify extents and enter the extents for the X and Y axes such that the range in magnitudes divided by the number of intervals is equal to the desired tick mark interval. The resulting tick mark interval may not be exactly as described above. DPlot will adjust the extents set with the Extents/Intervals/Size command such that the tick mark interval is some multiple of 1.0, 1.5, 2.0, 2.5, 3.0, 4.0, 5.0, 6.0, or 8.0 times a power of 10. For example, if 6 tick mark intervals are specified on an axis and the extents are set to 0.0 to 10.0, DPlot adjusts the upper extent to 12.0 so that the tick mark interval is 2.0 rather than 1.6667. |
