Transformation class resource descriptions

trXMinF
Specifies a minimum X coordinate value that defines the lower bound of the X-Axis coordinate system. If trXMinF is greater than trXMaxF, the values will be exchanged before they are used to establish coordinate boundaries. If the axis is logarithmic, trXMinF must be greater than 0.0. If the axis is irregular, trXMinF is constrained to lie within the bounds of the irregular coordinate system as established by the X-Axis coordinate array.

This resource may be intercepted or disabled by:

Default: 0.0

trXMaxF
Specifies a maximum X coordinate value that defines the upper bound of the X-Axis coordinate system. If trXMaxF is less than trXMinF, the values will be exchanged before they are used to establish coordinate boundaries. If the axis is irregular, trXMaxF is constrained to lie within the bounds of the irregular coordinate system as established by the X-Axis coordinate array.

This resource may be intercepted or disabled by:

Default: 1.0

trXReverse
If the axis is linear or logarithmic, setting trXReverse True results in a coordinate system that increases from right to left, rather than in the usual direction from left to right. If the axis is irregular, setting trXReverse True results in a reversal of the direction of increasing coordinates as initially defined by the ordering of the elements of the X-Axis coordinate array.

This resource may be intercepted or disabled by:

Default: False

trYMinF
Specifies a minimum Y coordinate value that defines the lower bound of the Y-Axis coordinate system. If trYMinF is greater than trYMaxF, the values will be exchanged before they are used to establish coordinate boundaries. If the axis is logarithmic, trYMinF must be greater than 0.0. If the axis is irregular, trYMinF is constrained to lie within the bounds of the irregular coordinate system as established by the Y-Axis coordinate array.

This resource may be intercepted or disabled by:

Default: 0.0

trYMaxF
Specifies a maximum Y coordinate value that defines the upper bound of the Y-Axis coordinate system. If trYMaxF is less than trYMinF, the values will be exchanged before they are used to establish coordinate boundaries. If the axis is irregular, trYMaxF is constrained to lie within the bounds of the irregular coordinate system as established by the Y-Axis coordinate array.

This resource may be intercepted or disabled by:

Default: 1.0

trYReverse
If the axis is linear or logarithmic, setting this trYReverse True results in a coordinate system that increases from right to left, rather than in the usual direction from left to right. If the axis is irregular, setting trYReverse True results in a reversal of the direction of increasing coordinates as initially defined by the ordering of the elements of the Y-Axis coordinate array.

This resource may be intercepted or disabled by:

Default: False

trLineInterpolationOn
This resource controls the rendering of the lines between defined points for XyPlot and for graphics primitives drawn using NhlDataPolyline or NhlDataPolygon. If set False, lines between the points are drawn as straight lines in NDC space. If set True, points are interpolated between the defined points in order to map the line into the data space.

This resource is disabled by:
