CHAPTER 15 Working with Graphs
DataWindow Designer User’s Guide 447
Table 15-11: Properties for scaling on numeric axes
Using major and
minor divisions
You can divide axes into divisions. Each division is identified by a tick mark,
which is a short line that intersects an axis. In the Sales by Printer graphs shown
in “Examples” on page 432, the graph's Value axis is divided into major
divisions of 50 units each. DataWindow Designer divides the axes
automatically into major divisions.
❖ To define divisions for an axis of a graph:
1 To divide an axis into a specific number of major divisions, type the
number of divisions you want in the MajorDivisions box.
Leave the number 0 to have DataWindow Designer automatically create
divisions. DataWindow Designer labels each tick mark in major divisions.
If you do not want each tick mark labeled, enter a value in the
DisplayEveryNLabels box. For example, if you enter 2, DataWindow
Designer labels every second tick mark for the major divisions.
2 To use minor divisions, which are divisions within each major division,
type the appropriate number in the MinorDivisions box. To use no minor
divisions, leave the number 0.
When using logarithmic axes
If you want minor divisions, specify 1; otherwise, specify 0.
Property Meaning
Autoscale If selected (the default), DataWindow Designer automatically
assigns a scaling for the numbers along the axis.
Round To,
Round To Unit
Specifies how to round the end points of the axis (note that this
just rounds the range displayed along the axis; it does not round
the data itself).
You can specify a number and a unit. The unit is based on the
datatype; you can specify Default as the unit to have
DataWindow Designer decide for you. For example, if the Value
axis is a Date column, you can specify that you want to round the
end points of the axis to the nearest five years. In this case, if the
largest data value is the year 1993, the axis extends up to 1995,
which is 1993 rounded to the next highest five-year interval.
Minimum Value,
Maximum Value
The smallest and largest numbers to appear on the axis (disabled
if you have selected Autoscale).
Scale Type Specifies linear or logarithmic scaling (common or natural).
Scale Value Specifies whether values are displayed as actual values or as a
cumulative value, a percentage, or a cumulative percentage.
