Two Bar Charfs Made on a Typewriter.

1. For the employee in a business office, lacking the tools and the skill in drawing and

lettering of a draftsman, the typewriter offers an opportunity for quick and easy preparation of graphic presentation of data through charts and diagrams. It solves the problem of lettering and asures that vertical and horizontal lines will be at right angles without the use of a drawing board and T-square.

2. Making bar charts is a simple process. By letting one space on the machine represent

a unit quantity, the character selected for a given bar can be struck the correct number of times to represent any specified amount. There are several characters which when written so that one row exactly touches the next one will make a very attractive "all over" pattern.

A Sector Chart Made on a Typewriter.

A sector chart can be made quickly -and easily on a typewriter by the following method:

1. Draw the circle of convenient size with any ordinary school compass.

2. Indicate the division of the circle into its parts by a protractor and draw the dividing

lines in ink.

3. Type in the names of the sectors.

4. With the compass set as it was to draw the original circle, draw another circle exactly

like it on a sheet of thin typewriter second paper. By running the sharp point of the compass around the circle several times on the thin paper, the circle will drop out and leave a hole in the second sheet.
