This item pops up a window that allows you to set plot attributes for mesh plots. If you select a mesh 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 mesh plots will be unchanged. If you select this item without selecting a mesh plot first, you will have to select a mesh plot before you can apply the changes. Note that if you make any changes and then select a mesh 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.
The
Mesh plot attributes
window looks like
Mesh 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 mesh plots. The attributes include things like whether the legend will be shown and how much of the mesh to draw.
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.
When this toggle is selected, a subset of the mesh is drawn, sometimes drawing only the outline. How much of the mesh is drawn is set by the Error text field, which is grayed out until this toggle is activated.
While this works for both 2D and 3D data files, using this option yields an outline only for 2D data sets.
This text field becomes active once you turn on the Outline only toggle. The numeric value in this field ranges from 0.0 to 1.0, where 0.0 means draw the entire mesh and 1.0 means remove as much as possible. This number actually controls how much of the mesh is drawn by signifying how much deviation (error) from a straight line or surface is allowed before lines/surfaces will be combined. Thus, if the allowed deviation is 0, then all lines must be drawn. If the allowed deviation is 0.5, then lines can have a significant angle and still be collapsed into one line. Therefore, for some meshes and all 2D meshes, the only real options are either 0.0 or 1.0. The default is 0.01.
When plotting a point mesh, you can set the size of the points. The default size is 0.05.
