odds and ends

[Daniel J S. <dan...@ie...>]

I noticed that molecule.dem is still not in all.dem, if Ethan wanted that one in the list.  (The second image would make a good animation to see both top and bottom of the hyperplane border.)

The demo

  set title "set pm3d corners2color c3"

has the text for the color bar off of the plot.  There is enough space to push the sample boxes upward and make more room for the color bar.

The demo "transparent_solids.dem" produces color differences between X11 and PostScript.  The interlocking tori example is all one color in X11, blueish purple.  In PostScript, the color fades from white to light red.  The Kuen's surface in X11 is grayscale where every element is the same shade.  In PostScript, it comes multicolored.

Also, somehow with the tori example I ended up with "view" and "scale" coordinates in a huge sans seriff font... Here's how I did it.  Run gnuplot and type:

load 'transparent_solids.dem'
load 'transparent_solids.dem'

On the second load of the demo the first graph has the font too large for the coordinates.  (There should be no way of controling the coordinate fonts, is that right?)

For 'transparent.dem'.  The font I see in the key is some strange glyph and different between X11 and PostScript.  (I've not followed font issues closely.)  The lines in the density function for red and yellow do not show up in PostScript.  The overlay of the third plot in this demo doesn't work the same for PostScript either.

The PDF terminal crashes gnuplot on demo "transparent_solids.dem".
