ARC/INFO Hints
There are two lines that should be added to the $HOME/app-defaults/Mwm file. These lines allow ARC to automatically place popup windows:
*clientAutoPlace: FALSE
*interactivePlacement: FALSE
There are a few general tools available in ARCPLOT that may assist in the design or production of maps and graphics. When using 'DISPLAY 9999,' ARCPLOT defaults to a black background; this is a problem with the 'true color' display of value--black objects will be visible on paper, but invisible on the display, and vice-versa for white. The remedy for this is to include the following line in either a .cshrc or .login file:
setenv CANVASCOLOR WHITE
When using nineteen inch monitors, it is possible to specify a display canvas size that has (as far as ARC is concerned) the same dimensions as an 8.5 by 11 sheet of paper. The dimension for portrait layout are 691 by 930. The dimensions for landscape layout are 896 by 727.
All AMLs can be executed in two ways: specifying an AML path and running with the &RUN directive; or by placing the AMLs in an atool directory and running them as a standard command. The $ARCHOME/atool directory can be used, or the AMLs can be placed in another directory and linked into $ARCHOME/atool subdirectories. The AMLs can also be placed in any other directory, with subdirectories for each module (arc and arcplot), and use the &ATOOL directive to specify the directory path (see the &ATOOL page in the AML User's Guide).
The AMLs discussed in this document, for the most part, follow a naming convention. For the first character:
- P
- point or node displays.
- L
- line, route or section displays.
- C
- choropleth area displays.
- G
- graduated symbol area displays.
- D
- dot density area displays.
- R
- raster (grid) area displays.
- S
- surface displays.
For each additional character (one for each variable displayed):
- H
- hue.
- V
- value.
- I
- intensity.
- O
- orientation
- S
- shape.
- T
- texture.
- Z
- size.
- B
- box (used with points only).
- C
- circle (used with points and graduated symbols only).
- G
- cartoGram (used with graduated symbols only).
- D
- density (used with dot density only--all are DD).
- F
- fishnet (used with surfaces only).
- AO
- angle (for single variable displays only: cao, pao)
- ISO
- isoline (used with surfaces only).
Other codes include:
- P
- pie (graduated circles with subdivisions).
- L
- legend (gcl, ggl, gpl, sfl; al - single variable; ol - orientation)
- BL
- bivariate legend.
- CC
- complementary colors.
- DH
- dual hue colors.
- EE
- equiprobability ellipse (and eel - legends).
- IL
- choropleth area intersecting lines with PAT data (and cill - legends).
- TL
- choropleth area intersecting lines with lookup tables.
- RGB
- red, green and blue (and rgbl - legends).
