Reference line plot attributes menu item
This item pops up a window that allows you to set plot attributes for reference line plots. If you select a reference line plot from the
Active plots
list in the MeshTV
Main
window, then attributes you change and apply will be applied to the selected plot. Unselected reference line plots will not be changed. If you select this item without selecting a reference line plot first, you will have to select a reference line plot before you can apply the changes. Note that if you make any changes and then select a reference line plot, you will lose your changes since the window will update with the attributes of the selected plot.
You can modify the default settings for attributes of future plots by opening this window, making your changes, and then pressing the
Make default
button. This affects only future plots, not existing ones, and stays in effect only for the remainder of the current MeshTV session unless you also select
Save settings
from the
File
menu.
Reference line plot attributes window
The
Reference line plot attributes
window looks like
Reference line plot attributes
, if you are using MeshTV's defaults. If you aren't, the values might be different.
This window allows you to set the attributes assigned to existing or future reference line plots. The attributes include things like setting the endpoints which define the line, and setting the line's color, style, and width attributes.
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.
Endpoints area
This area allows you to change the endpoints of existing reference line plots. You can specify whether the line should be absolute (a straight line from the starting point to the ending point) or logical (a line which follows the mesh.)
Absolute endpoints radio button
When you switch a graphics output window into line-out mode (holding down the right mouse button and selecting
Mode
and
Line-out
from the pop-up menu), you can draw lines in the window.
Two kinds of lines can be drawn. By default, straight lines with absolute endpoints are drawn, though you can switch to drawing logical lines that follow the mesh by selecting the
Logical
toggle in the
Line-out
window found under the
Controls
menu.
When you select a reference line in the
Active plots
area, you can modify its endpoints by selecting the
Absolute endpoints
radio button and putting the coordinates of the starting point into the
From
text field and the coordinates of the ending point into the
To
text field. After you hit
Apply
, the endpoints of the line will snap to the points you entered. Note that this option applies only to existing lines, so the setting is not saved when you hit the
Make default
button.
Logical endpoints radio button
When you switch a graphics output window into line-out mode (holding down the right mouse button and selecting
