Drawing a zig-zag Trail in Python?
I'd like to draw something like an animal track. Between each point is a
line. Perhaps the line would have an arrow showing the direction of
motion. There should be x-y coordinates axises. PIL? MatPlotLib, ??

I can't catch the concept of "hardware insert/delete line feature"which
described in ncurses's control subroutines.
Examples for the idlok subroutine are:
1.. To enable curses to use the hardware insert/delete line feature in
2.. To force curses not to use the hardware insert/delete line feature in
the user-defined window my_window , enter:

...adding lines to UI edit text control
I am trying to programmatically add bits of text to an edit text box.
It works fine, until I insert a new-line character. Then the next bit
of text I add produces an "error using horzcat: All matrices on a row
in the bracketed expression must have the same number of rows".
If I manually insert text, including new-line characters (the enter
key), it works fine. However, when I close the window containing the
text box, and reopen it, trailing spaces are added to short lines.
I assume these two behaviors are related. I don't need to manually
add trailing spaces do I?
I want to draw a line in a image, for example
I = double(imread('myImage.jpg'));
p1 = [1,1];
p2 = size(I);
and a want to draw a line from p1 to p2 on image I. How can I do
this? Is there a builtin function or do I have to write my own line
drawing funtion, for example implement the Bresenham line drawing

I'm implementing simple CLI (flat model, no tree-style menu etc.). Command
line looks like this: <command> <param1> <param2> ... <paramN> (where
And idea is pretty simple:
1) get whole string of input line
2) preset table of strings matching <command>
3) preset table of function calls
4) scan <command> table for string, if match - call matching function (I
declare ALL callback functions as having the same format)

is if pressing 'Enter' continuously ...Hidden lines in a drawing view
I'm sure this is a basic question so forget me for my ignorance but if I RC

Is there a reset option to bring the line back or some to this effect?
Select Menu "View" > "Hide/Show Anotations" and the hidden lines will
show up in gray. Select the ones you want to un-hide by picking.

Hello to all,
how can I place two lines in the same plot with colors defined by me?
The Help section suggested the following:
set(0,'DefaultAxesColorOrder',[0 0 0;. . .;. . .])
but it doesn't seem to work. I also tried:
plot(x,y,'Color',[1 0 1])
but ML gives an error message when I would like to plot two lines
plot(x,y,'Color',[1 0 1],v,w,'Color',[0 0 1])
Any help would be greatly appreciated,
try this :

Is there any way to get rid of the nagging questions Solidworks asks over

Example: "Some of the models referenced in this document have been

Now, what kind of dumbass question is that? Of couse I want to save the
models! That's what is supposed to happen when you "save"! This happens
evertime you make a change in an assembly and try to save it.
One would think there would be a way to turn off those nagging questions.

I`ve had a HP Laserjet 5 printer for a while, and about 300 pages ago I put
in a new toner. Suddenly today it has started laying down horizontal black
lines, about 5mm in width, repeated every 9cm. Nothing has changed with the
printer, it`s not been moved or knocked. As it started the lastest print
job, which has these lines on, it started squaking rythmically as it was
bringing the paper through.
I`ve tried turning it off and on and swearing at it, as well as removing the
toner cartridge and reseating. Any other ideas that might help, suggestions

I need to change the way the grid is being drawn.
The horizontal lines remain the same, but the vertical lines should become a kind of hyperbolas, rather than straight lines. How would you advise me to do that? Is it possible to change the way grid is being drawn? Or it is better for me to write a script that would draw the grid and call it after creating the figure but before plotting the data?
Also I would like to know wheter there are any specific line styles used in plotting of the grid and whether I can use it somehow.
Thanks for the answers.

Does anyone have a macro or method to create a BOM or basically a make
from on a part drawing. I want to show all inserted parts (bodies) in a
BOM like format on a part drawing. And have it auto update if bodies
are added or removed.
I did find one that allowed you to enter in properties to fill out the
BOM as you can put a normal BOM on a part's drawing. But this is a
manual method, I would really like an auto one.
Just thought I would ask before I started one myself. We also use a PDM
(DBWorks) and I might find it easier to just get the data from there as
it already does know about...Freehand drawing in !Draw?
