Viva for me *is* being launched by ADE, so using the viva.trace variables isn't working as Andrew warns.
I tried changing definition of y0 using the DRM, but this *also* had no effect on the yellow trace plotted by viva.
The default trace thickness is so thin as to be almost invisible on initial display, and certainly invisible once snapped and inserted into a presentation and shown on a projector.
If possible, I'd also like to default to sold line vs dotted, AND to use a white background with black axes.
Some of the viva settings seem relevant based on names but don't seem to have any effect. Of all of these settings, only the first seems to do anything:
viva.axis font string "Default,12,-1,5,75,0,0,0,0,0"
viva.axis minorGridForeground string "white"
viva.axis background string "white"
viva.axis foreground string "black"
viva.axis majorGridForeground string "white"
viva.trace lineThickness string "medium"
And as long as I'm asking for the moon, any way to make the grid color be something other than "almost exactly the same as the background" ?
It is clear that the defaults for this tool were selected by someone that doesn't need to use this tool.
