Vector plot attributes menu item

This item pops up a window that allows you to set plot attributes for vector plots. If you select a vector 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 vector plots will not be changed. If you select this item without selecting a vector plot first, you will have to select a vector plot before you can apply the changes. Note that if you make any changes and then select a vector 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.

Vector plot attributes window

The Vector plot attributes window looks like Vector 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 vector plots. The attributes include things like the scale (length) of the vectors, the head size of the vectors, and the total number of vectors to display.

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.

Scale text field

This text field governs the scale (length) of the vector.

Head size text field

This text field governs the size of the head on the vector. The default is 0.25, which means that the head takes up 1/4th of the length of the vector.

Nvectors text field

This text field allows you to select the number of vectors to display. The default is 400, though this number is too small for many plots. If you increase the number too much, however, the vectors will blanket the object, obscuring both themselves and any other plots.
