4.0 Annotation

Annotation window

The Annotation window looks like Annotation window , if you are using MeshTV's defaults. If you aren't, the values might be different.

The Annotation window allows you to control general options, like whether to display file information and plot legends. It also allows you to control both 2D and 3D options, like whether grid lines and labels are shown, where tickmarks are placed if at all, and so forth. There is also a special button to set the attributes for making viewgraphs.

If you don't see a description for an item in this window, check in the Shared items section near the front of the chapter.

General options

Items in this section apply to all plots, rather than being specific to 2D or 3D plots.

User info toggle button

This button turns user information legends on and off. The legend displays the name of the user and the current date.

Database info toggle button

This button turns database information legends on and off. This legend lists the filename, time, and cycle number of the problem, if they exist.

Plot legends toggle button

This button indicates whether or not to plot legends. This is a quick way to turn off all legends and then bring them back. To turn on/off individual legends, you need to bring up the associated plot attribute window. For example, for a particular boundary plot, you need to select that plot in the Active plots list and then bring up the Boundary plot attributes .

Viewport type options

There are three options for the viewport type. The standard option is Default , which is a viewport with coordinates of 0.2, 0.95, 0.15, and 0.9. A second option is Full , which makes the viewport as large as possible. This can lead to problems with legends, so you might have to turn those off. The last option is User defined , and when you select this option, the Viewport text field becomes sensitive. Viewports are specified by four numbers, each ranging from 0.0 to 1.0. The first and second of the four numbers are the x-min and x-max values, and the third and fourth numbers are the y-min and y-max values. The lower left-hand corner of the viewport is 0, 0, and the upper right-hand corner is 1, 1.

Viewport text field

This text field is only active when the Viewport type is set to User defined . Viewports are specified by four numbers, each ranging from 0.0 to 1.0. The first and second of the four numbers are the x-min and x-max values, and the third and fourth numbers are the y-min and y-max values. The lower left-hand corner of the viewport is 0, 0, and the upper right-hand corner is 1, 1.

Verbose label and option menu

This option controls when to print the database name, problem cycle, and problem time in individual plots. When this option is On , the information is always plotted for all appropriate plots. When this option is Off , the information is never plotted. When this option is set to Diff , MeshTV will only display the information for a plot when it differs from what is already displayed at the top of the graphical output window.

2D axes

This button provides a shortcut for turning 2D axes on or off. When the axes are off, the 2D axes options are grayed out.

2D axis labels options

This item allows you to select which axes in a 2D plot to label. You can label both axes by selecting Both axes, just the bottom axis by selecting Bottom , just the left axis by selecting Left , or you can turn labels off by selecting Off . The default is to label both axes.

2D grid lines options

This item allows you to select in which direction in a 2D plot to have grid lines. You can choose X axis to have grid lines just along the X axis, Y axis to have grid lines along just the Y axis, or Both axes to have grid lines along both axes. Off , which is the default, turns off all the grid lines.

2D tick marks options

With this option, you can place tick marks on axes in a 2D plot. You can choose Off to turn off tick marks, Bottom to have tick marks on just the bottom axis, Left to have tick marks on the left axis, Bottom-left to have tick marks on both axes, or All to have tick marks on all four axes. The default is Bottom-left .

2D tick mark locations options

This option allows you to specify where your tickmarks will be placed in a 2D plot. You may choose Outside to have tick marks outside the axes, Inside to have them inside the axes, and Both to have them appear both inside and outside the axes. This option is only active if at least one of the axes has tick marks.

3D axes

This button provides a shortcut for turning 3D axes on or off. When the axes are off, the 3D axes options are grayed out, except for the 3D triad option.

3D axis labels options

This item allows you to select which axes in a 3D plot to label. Click the box beside each axis you wish to label, or leave all unselected if you want no labels.

3D grid lines options

This item allows you to select the direction grid lines in a 3D plot. Click the box beside each axis you want to have grid lines, or leave them unselected if you want no grid lines.

3D tick marks options

With this option, you can specify which axes in a 3D plot will have gridmarks. Click the box beside each axis you want to have tick marks, or leave all the axes unselected if you want no tick marks.

3D tick mark locations options

This option allows you to specify where to place your tickmarks in a 3D plot. You may choose Outside to have tick marks outside the axes, Inside to have them inside the axes, and Both to have them appear both inside and outside the axes. This option is only active if at least one of the axes has tick marks.

3D triad radio buttons

This option allows you to turn the 3D triad on and off. The triad is an icon located in the lower left hand corner. It contains three lines which meet at one point and align with the X, Y, and Z axes. When you rotate a 3D image, the triad rotates and displays the orientation of the X, Y, and Z axes.
