| 在 C++： | QValue3DAxis |
| 继承： |
This type provides an axis that can be given a range of values and segment and subsegment counts to divide the range into.
|
autoAdjustRange : bool |
Defines whether the axis will automatically adjust the range so that all data fits in it.
|
formatter : Value3DAxisFormatter |
The axis formatter to be used. Any existing formatter is deleted when a new formatter is set.
|
labelAutoAngle : real |
The maximum angle the labels can autorotate when the camera angle changes. The angle can be between 0 and 90, inclusive. The default value is 0. If the value is 0, axis labels do not automatically rotate. If the value is greater than zero, labels attempt to orient themselves toward the camera, up to the specified angle.
|
labelFormat : string |
The label format to be used for the labels on this axis.
格式字符串支持的以下转换说明符、长度修饰符和标志的提供通过
printf()
在标准 C++ 库：d、i、o、x、X、f、F、e、E、g、G、c。
若
GraphsItem3D::locale
is anything else than
"C"
，支持的说明符限于：d、e、E、f、g、G 和 i。另外，仅支持精度修饰符。其余格式来自默认

|
labels : list |
The labels for the axis.
注意： Setting this property for Value3DAxis does nothing, as it generates labels automatically.
|
labelsVisible : bool |
Defines whether the axis labels are visible in the primary graph view.
默认值为
true
.
|
max : real |
The maximum value on the axis. When setting this property, the minimum value is adjusted if necessary, so the range remains valid.
|
min : real |
The minimum value on the axis. When setting this property, the maximum value is adjusted if necessary, so the range remains valid.
|
orientation
:
Abstract3DAxis
.
AxisOrientation
|
The orientation of the axis.
|
reversed : bool |
若
true
, the axis will be rendered in reverse. That is, the positions of the minimum and maximum values are swapped when the graph is rendered. This property does not affect the actual minimum and maximum values of the axis.
|
segmentCount : qsizetype |
The number of segments on the axis. This indicates how many labels are drawn. The number of grid lines to be drawn is calculated with the following formula:
segments * subsegments + 1
. The preset default is
5
. The value cannot be below
1
.
|
subSegmentCount : qsizetype |
The number of subsegments inside each segment on the axis. Grid lines are drawn between each subsegment, in addition to each segment. The preset default is
1
. The value cannot be below
1
.
|
title : string |
The title for the axis.

|
titleFixed : bool |
The rotation of axis titles.
若
false
, axis titles in the primary graph view will be rotated towards the camera similarly to the axis labels. If
true
, axis titles are only rotated around their axis but are not otherwise oriented towards the camera. This property does not have any effect if the
labelAutoAngle
特性值为 0。默认值为
true
.

|
titleOffset : real |
The position of the axis title on the axis. The value must be between
-1.0f
and
1.0f
Default value is
0
.
另请参阅 title and titleVisible .
|
titleVisible : bool |
Defines whether the axis title is visible in the primary graph view.
默认值为
false
.
