This type provides an axis that can be given a range of values and segment and subsegment counts to divide the range into.
[since QtDataVisualization 1.1] formatter : ValueAxis3DFormatter |
The axis formatter to be used. Any existing formatter is deleted when a new formatter is set.
该特性在 QtDataVisualization 1.1 引入。
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
AbstractGraph3D::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
区域设置
对于应用程序。

[since QtDataVisualization 1.1] 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.
该特性在 QtDataVisualization 1.1 引入。
segmentCount : int |
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 : int |
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
.
