Axes

Tecplot 360 automatically enables axes for 3D, 2D, XY, and Polar plot types. There are five distinct sets of axes, one for each plot type. When axes are generated, axis labels, positions, spacing, and tick labels are created. You can adjust these settings through theAxis Detailsdialog (accessed via thePlotmenu).Axis DetailsEach page of the dialog controls a different aspect of the axes, and each page is available for every axis.

Axis Display

Use theAxis Details"Show Axis" toggle in the dialog to turn on axis display. By default, showing an axis displays the axis line, tick marks, tick labels, and axis title. You can individually disable any of these components, including the axis line.

To edit an axis from theAxis Detailsdialog, use the axis buttons ([X], [Y], [R], etc.) at the top of the dialog to indicate which axis you are working on. To edit a different axis, select a different axis button.

Axis Variable Assignment

For 2D and 3D Cartesian plots, Tecplot 360 initially assigns the first and second variables in the data set to the X and Y axes, respectively. For 3D axes, the third variable in the data set is assigned to the Z axis.

To change the variable assignment for 2D and 3D axes, select "Assign XY" or "Assign XYZ" from thePlotmenu. For line plots, assigning axis variables is part of defining a mapping. For more information, seeXY and Polar Line Plots。

You can modify the axis range using theAxis Details"Range" page of the dialog, which can be accessed via thePlotmenu, or by right-clicking on an axis in the plot. SeeAxis Range Options for XY and 2D/3D Plots和Axis Range Options for Polar Plots

。

When working with axis ranges, keep the following definitions in mind:: Axis Range
Specifies the minimum and maximum data values displayed along the axis. The axis range fits the values of the first variable assigned to that axis. If you deactivate the current layer and activate another, you may need to reset the axis range.: Axis Length
Axis Scaling: Specifies the ratio of axis length to axis range.

Axis range options for XY plots and 2D/3D plots

This section discusses the options available on the "Range" page for XY line plots, 2D Cartesian plots, and 3D Cartesian plots, located in theAxis Detailsdialog.

The "Range" page contains the following options:

Show Axis

Check this checkbox to display the selected axis in the plot (n). Use the [X], [Y], etc. buttons to the right of this checkbox to select the axis to display.

Min

Enter the minimum value of the axis range.

Max

Enter the maximum value of the axis range.

Reset Range

Reset by selecting one of the following three options from the dropdown menuMax and Minfields:

Reset to Nice Values: Set the range slightly larger than the current axis variable range so that the axis starts and ends at major tick increments.
Set to Variable Min/Max: Set the range to the variable minimum and maximum values, taking blanking effects into account.
Make Current Values Nice: Round the axis range to the nearest major tick increment.

Preserve axis length when changing range

If this option is enabled and the axis is set to "Independent", changes to the X/Y ratio will affect the axis range but not its scaling. Disable this option to change both the axis range and axis scaling. SeeFigure 1.

Use log scale

The X and Y axes of 2D or XY line plots can use linear scaling (default) or logarithmic scaling. When logarithmic scaling is selected and "Auto Spacing" is enabled, large numbers will be displayed in scientific notation (e.g., 3.48x10⁵). It is strongly recommended to use "Auto Spacing" on logarithmic axes. Navigate to the "Ticks" or "Labels" page of the dialog and enable "Auto Spacing" to use this option.

Reverse axis direction

Enable this option to display the axis from high to low instead of low to high. Not applicable to 3D Cartesian plots.

Dependency

Select whether to set the axes as interdependent or independent. For XY line plots or 2D Cartesian plots, choose "Independent" or "Dependent".

When an XY line plot uses logarithmic scaling, the axes must be set to independent.

For 3D Cartesian plots, choose from the following options:

Independent: All axes are independent.
XY Dependent: The X and Y axes are interdependent, and the Z axis is independent.
XYZ Dependent: Changing the scaling of any axis will cause the other two axes to scale proportionally, maintaining the specified X/Y ratio and X/Z ratio.

Ratios (For 2D and 3D plots only)

2D Plot: If "Dependent" is selected, enter the ratio of X to Y.
3D Plots: If XY Dependence is selected, enter the ratio of X to Y.
3D Plots: If XYZ Dependence is selected, enter the ratio of X to Y and the ratio of X to Z.

Automatically Adjust Axis Range to Nice Values

Automatically adjust the axis range to the nearest major axis increment.

Size Factors (For 2D and 3D plots only)

If the axis is XY dependent, changing the X or Y size factor changes the other. If the axis is XYZ dependent, changing one size factor changes the other two.

Reset Size/Dependency

Reset the dependence controls to their default values.

Figure 1. Preserving length versus preserving scale while changing range (left); preserving length versus preserving scale while changing range in a Polar Line plot (right).

Axis range options for polar plots

Polar axes differ from any other axis type due to their cyclic nature. Each polar axis (Theta and R) has very different settings, unlike XY or XYZ axes. For the Theta axis, you can change the Theta mode, Theta period, and Theta values on the right circle; for the R axis, you can change the origin; for both axes, you can clip data to the axis range.

Show Axis

Check this checkbox to display the selected axis on the plot. Use the Theta, R, etc. buttons to the right of this checkbox to select the axis.

Minimum

输入轴范围的最小值。

Maximum

输入轴范围的最大值。

Reset Range

重置Max and MinSet the field by selecting one of three options from the dropdown menu.

Reset to Full Circle: Set the Theta range to cover the entire circle.
Reset to Fit: Set the range to be slightly larger than the current axis variable range, so that the axis starts and ends at major axis increments.
Set to Variable Min/Max: Set the range to the variable minimum and maximum values.
Fit Current Values: 将轴范围舍入到最近的主轴增量。

更改范围时保持长度

如果勾选，对 Theta 与 R 比率的更改将影响轴范围，但不影响其比例。取消勾选可同时更改轴范围和轴比例。请参阅Figure 1有关差异的图示。

使用对数刻度

R轴可采用线性刻度（默认）或对数刻度。当选择"自动间距"配合对数刻度时，大数值将以科学计数法显示（例如3.48x10）。⁵强烈建议在对数轴上使用"自动间距"。导航至对话框的"刻度"或"标签"页面，并启用"自动间距"以使用此选项。

反转轴方向

启用后，轴将从高到低显示，而非从低到高。不适用于3D笛卡尔图。

将数据裁剪至轴范围

对于极坐标折线图，数据可能超出轴边界。使用此功能可消除绘制在轴范围之外的数据。裁剪数据可针对每个轴独立设置。要激活或停用裁剪，请切换"将数据裁剪至轴范围"的开启或关闭状态。此功能图示见Figure 2.

Figure 2. An example of clipping polar data to an axis.

Theta模式

默认情况下，Theta轴以角度模式表示，范围为0到360。对于Theta轴，您可以使用弧度、角度或任意单位（其中任意模式将Theta范围设置为Theta轴变量的最大值和最小值）绘制角度。

要设置Theta模式，请从以下选项中选择：

0 - 360度
-180至180度
0至2Pi弧度
Pi至Pi弧度
适配变量最小值/最大值

选择任一选项将更改Theta模式、重置Theta轴范围并重置Theta周期。当Theta模式为弧度时，Tecplot 360将Theta标签显示为Pi的分数单位。

Theta周期

Theta周期指定形成完整圆所需的Theta范围。如果Theta模式为"角度"，则Theta周期强制为360；若为"弧度"，则周期为2 Pi；若为"适配变量最小值/最大值"，则周期可设置为任意值。

圆右侧的Theta值

"圆右侧的Theta值"设置可更改Theta轴的方向。默认情况下，此值为零，即零值（或等效值，如360度、720度等）显示在圆的右侧。您可更改此值以调整轴的方向。

R原点

R origin specifies the R value represented by the axis center. The effect of changing the R origin is displayed inFigure 3.

Figure 3. An example of changing the R-origin from a range of 0.3 to 0.6 on a polar plot.

Axis Grid Options

You can control grid lines and minor grid lines via the "Grid" page.Axis Detailsdialog, as shown below. On this page, you can customize the line type, line type length, line thickness, and grid line color for grid lines and minor grid lines.

Gridlines: Match the spacing of tick marks.
Minor Gridlines: Number of subdivisions for grid lines.

The spacing of grid lines is controlled by tick mark spacing; for more information, seeTick Mark OptionsRelated topics.

Gridlines, Minor Gridlines

To activate grid lines or minor grid lines, enable the "Show" option under these headings on the "Grid" page. Both types of grid lines have the following options:

Line Pattern

Select one of the following line types from the "Line Type" dropdown menu: Solid, Dashed, Dash-Dot, Dotted, Long Dash, or Double Dash-Dot.

Pattern Length (%)

(Theta axis only) Select the line type length from the dropdown menu, or enter a custom value.

Thickness (%)

Select the line thickness from the dropdown menu, or enter a percentage value relative to the frame height.

Gridline Color

Use the color picker to select the grid line color.

Gridline Draw Order

Except for 3D axes, all axes allow specifying the drawing order of grid lines. Grid lines can be drawn first (behind all other plot layers) or last (overlaying all plot layers).

Gridline Cutoff (R%)

(Theta axis only) Select the point along the R axis where Theta lines stop drawing.

In polar line plots, excessive grid lines in the central area may obscure data. You can specify the cutoff position of grid lines along the R axis for polar plots on the"Grid" page of the dialog.

Show Precise Dot Grid

Minor grid point grid is a set of small dots drawn at each minor grid line intersection. In line plots, the first valid mapped axis assignment controls the minor grid point grid. When either axis of the first valid line mapping uses a logarithmic scale, the minor grid point grid option is disabled for 3D Cartesian plots and line plots.

Tick Mark Options

Tick marks can be placed on each axis and labeled with numbers or text strings. You can use theAxis Details"Tick" page of the dialog to define tick marks and their positions. You can use theAxis Details dialog.

Show Ticks On

"Label" page of the dialog to define tick mark labels. For each plot type, you can display tick marks on different parts of the axis. (This description also applies to labels and titles.)

Sketch, XY line plots, and 2D Cartesian axes allow displaying tick marks in the following areas:

Axis Line: Represents the line of the specified axis.
Grid Border Bottom: By default, the axis line is located at the left/bottom of the grid border. The bottom of the grid border is the lower-left corner position of the grid, defined byAxis Details dialog.
Grid Border Top: the viewport settings on the "Region" page of the dialog. The top of the grid border is the upper-right corner position of the grid, defined byAxis Details dialog.

the viewport settings on the "Region" page of the dialog. Tick marks for 3D Cartesian axes can be displayed in the following areas:

Axis Line: The line that represents the specified axis.
Opposite Edge: The complementary line opposite to the axis.

Tick marks for the Polar R axis can be displayed in the following areas:

Axis Line

The line that represents the R axis.

All R-axes

Available only when "Draw Axis on Both Sides" or "Draw Perpendicular Axis" is enabled for the R axis. When the "All R Axes" setting is enabled, tick marks will be displayed on the additionally drawn axes.

Grid Border Start

The starting point of the polar grid region.

Grid Border End

The ending point of the polar grid region.

Grid boundary start and grid boundary end are available only when the polar plot does not form a complete circle. If the data forms a complete circle, there is no start or end point on which to draw tick marks.

Tick marks for the Polar Theta axis can be displayed in the following areas:

Axis Line: The line that represents the Theta axis.
Inner Circle: Available only when the R axis minimum (Min) is greater than the R axis origin (Max) value. The minimum and maximum values are located onAxis Detailsthe "Range" page of the dialog (seeAxis Range Options for Polar Plots). In this case, the center of the polar plot is a circle rather than a single point, so tick marks can be drawn on the inner circle.
Outer Circle: The outer edge of the polar grid region.

Major Tick Mark Length and Thickness

The length and thickness of major and minor tick marks can be set independently via the "Length" and "Thickness" fields.

Number of Minor Ticks Length and Thickness

To specify the number of minor tick marks, first turn off "Auto Spacing" at the bottom of the page. The number of minor tick marks can be set in the "Number of Minor Tick Marks" text field in the "Minor Tick Marks" section of the dialog, along with adjustments to their length and thickness.

There is no independent control option for displaying minor tick marks. To hide minor tick marks, enter 0 in the "Number of Minor Tick Marks" text field.

Tick Mark and Label Spacing

You can directly control the spacing between tick marks and labels, or use "Auto Spacing" (default) to calculate the optimal spacing. When the view changes (especially during zooming), Tecplot 360 recalculates the spacing. When "Auto Spacing" is enabled, Tecplot 360 also automatically calculates the number of minor tick marks.

The spacing value is shared between tick marks and tick labels. You can modify the spacing by adjusting the auto spacing, spacing, and anchor controls under "Tick Mark and Label Spacing" at the bottom of the page.

Tick Mark Label Options

ThroughAxis Detailsthe "Labels" page of the dialog, you can specify label attributes for each axis's tick marks.

Show Labels On

Depending on the plot type, the corresponding label display options are enabled.

For Sketch, XY Line, and 2D Cartesian Line plots, you can choose:

Axis Line: When toggled-on, axis labels will display on the selected axis line.
Grid Border Bottom: When toggled-on, axis labels will display at the bottom of the grid.
Grid Border Top: When toggled-on, axis labels will display at the top of the grid.

For 3D Cartesian Line plots, choose from the following options:

Axis Line: When toggled-on, axis labels will display on the selected axis line.
Opposite Edge: When toggled-on, axis labels will display on the opposite edge of the plot.

For Polar Line plots, choose from the following options:

Axis Line: When toggled-on, axis labels will display on the selected axis line.
Inner Circle: When toggled-on, axis labels will display on the inner edge of the polar grid area. (Available only when the R-axis minimum is greater than the R-origin value.)
Outer Circle: When toggled-on, axis labels will display on the outer edge of the polar grid area.

Color and Font

Select the color and font for label display. (SeeFont Folders and Fallbackfor how fonts work in Tecplot 360.)

Number Format

Use the "Specify Number Format" dialog to select the number format for axis labels.

Offset from Line (%)

Enter the offset of tick labels relative to the axis.

Orient Labels

Choose from the following additional label display options:

At Angle: Labels oriented at a specified angleAngledropdown menu.
Parallel: Labels are parallel to the axis.
Perpendicular: Labels are perpendicular to the axis.
Angle (deg): If "Orient Labels" is set to "By Angle", specify the orientation of tick labels relative to the axis. The angle is measured counterclockwise from the axis (in degrees).

Show Label as Axis Intersection

[2D, XY, and Polar only] - When toggled-on, labels are drawn at the intersection of the two axes. Use this switch when axis labels collide or stack at the intersection.

Erase Behind Labels

When toggled-on, a rectangle (using the frame background color) is added behind the labels to enhance label visibility.

Label Skip

Specify the interval between tick labels.

Tick Mark and Label Spacing: You can directly control the spacing of ticks and tick labels, or use automatic spacing (default) to calculate the optimal spacing for ticks and tick labels. When you change the view (especially when zooming), Tecplot 360 recalculates the spacing. When automatic spacing is selected, Tecplot 360 also automatically calculates the number of minor ticks.

间距值在刻度和刻度标签之间共享。您可以通过调整Axis Details dialog.

Use the Auto Spacing, Spacing, and Anchor controls at the bottom of the Scale or Labels page of the dialog to change the spacing.

坐标轴标题是标识坐标轴的文本标签。默认情况下，Tecplot 360使用分配给该坐标轴的变量名称来标记每个坐标轴。

通过Axis Details在对话框的"Title"页面，您可以为每个坐标轴标题指定以下属性：

Show Title On

对于任何绘图类型，您可以指定坐标轴标题的显示位置。启用"At Axis Line"可将标题直接显示在对应坐标轴上。其余可用选项取决于绘图类型。
