| Type |
Integer
(0..2) |
| Summary: |
Sets
the scale mode for the X axis (the Y axis on horizontal graphs) |
|
Description:
The XAXISSTYLE property sets
the method for determining the scale and range of a graph's X axis (or
the Y axis of horizontal bar graphs and Gantt charts). This property
doesn't apply to pie charts or polar graphs.
The effect of XAXISSTYLE depends on whether or not you've set values
for the XPosData property. Bubble, lin/log, and log/log graphs always
have XPosData values, scatter graphs generally do, and other graph types
(except pie and Gantt charts) can have them if you choose.
Without XPosData
If you don't provide XPosData values, each data point in each data
set has an explicit Y value (determined by either the ST_DataSet{0..}
or the DB_DataSets attribute) and an implicit X value.
| Value |
Effect |
| 0 |
Zero origin The X axis
always begins at 0 (1 for bar graphs) and has one tick mark per
point. You can't set a minimum value, maximum value, or number of
ticks for the axis. |
| 1 |
Variable origin This
setting has no effect--it works just like setting 0 (zero origin). |
| 2 |
User-defined You can
specify the number of tick marks for the X axis using the XAxisTicks
property. However, you can't set the minimum and maximum values
for the X axis--any settings for XAxisMax and XAxisMin are ignored.
For details, see the entry for XAxisTicks. |
With XPosData
Graphs with XPosData values are true X-Y graphs--each point has
both an explicit X value (determined by either the ST_XPosDataSet{0..}
or the DB_XPosDataSets attribute) and an explicit Y value (determined
by either the ST_DataSet{0..} or the DB_DataSets attribute).
In this type of graph, the XAxisStyle property provides the same control
over the X axis as the YAxisStyle property provides over the Y axis.
| Value |
Effect |
| 0 |
Zero origin The Graph
control automatically calculates the X axis range based on your
XPosData values. The range includes the X origin (zero) and extends
at least far enough in the positive and negative directions to include
all XPosData. You can't set a minimum value, maximum value, or number
of ticks for the axis. |
| 1 |
Variable origin The
Graph control attempts to zoom in on your XPosData values when it
calculates the X axis range. The range is made at least wide enough
to include all XPosData values, but it doesn't necessarily include
the X origin (zero). You can't set a minimum value, maximum value,
or number of ticks for the axis.
This setting is useful when all your XPosData values are clustered
in a narrow range that doesn't include zero. |
| 2 |
User-defined The X axis
is drawn according to your settings for the minimum, maximum, and
number of ticks. Refer to the XAxisTicks, XAxisMax, and XAxisMin
properties. |
Remarks:
None.
| Example... |
<CFXGRAPHICSSERVER
... XAxisStyle="1"
... >
This
would set the X Axis Style to 1. The exact effect would depend
on the setting of XPosData.
