IDEAS
A selection of ideas and applications to develop and and extend the use of MSW Logo.

A Pie chart

This is a fairly simple way of making parts of a pie chart. (Can it be simplified?)

First create the procedure pie..

to pie :fraction :size
arc :fraction*360 :size
rt 180
fd :size
bk :size
rt :fraction*360
fd :size
bk :size
rt 180
end

Create pie chart segments by typing pie along with the fraction you want to display and the radius of the displayed segment. E.g:

pie 0.7 80

pie 0.3 80

A LOGO screen ruler

This is a useful way of investigating the relationship between LOGO distances and distances in the real world

Create the ruler procedure...

to ruler :n
label :n
lt 90
fd 15
rt 180
fd 15
lt 90
fd 3
repeat 9 [lt 90 fd 5 rt 180 fd 5 lt 90 fd 3]
if :n > 90 [stop]
ruler :n+10
end

Use the command ruler 0 to automatically create a ruler beginning at 0

Note: The marks on this example are not the same as LOGO measurements. What changes would you make to the procedure to correct it?

Telling the time

How could you improve this clock? - Visit the procedure bank to download the procedure used to make it.
