MathType Tip:
Using MathType to Make Charts, Grids, and Number Lines
Applies to:
| |
MathType 4 and later (Windows)
MathType 5 and later (Macintosh) |
|
Situation
Many customers are interested in making blank grids, and number lines
for inclusion in course materials. You can create these items, but it is important to remember that
MathType is designed to typeset mathematical expressions. Grids, graphs, and
number lines may be easier to create in programs designed for that purpose, such as
drawing programs. By manually
manipulating MathType's templates, spacing factors, and positioning controls, you can create these
items, but the process is time-consuming.
Before you begin
This Tip assumes you already have general knowledge of nudging,
manually repositioning individual equation elements in MathType, and the
commands in MathType's menus, particularly the Format menu. If you are not familiar with
these things, refer to the MathType documentation before preceding with this
article.
Creating charts and grids
MathType allows you to place dividing lines in matrix
templates, allowing you to simulate a Cartesian plane. Using a matrix
template without dividing lines allows you to create
things like pictographs and statistics charts, as in the examples
below:
(a)![\[\begin{array}{c}
{\text{What is the ratio of diamonds to hearts?}} \\
\begin{array}{*{20}{c}}
\begin{array}{l}
\diamondsuit \,\,\diamondsuit \,\,\diamondsuit \,\,\diamondsuit \\
\diamondsuit \,\,\diamondsuit \,\,\diamondsuit \,\,\diamondsuit \\
\end{array} & \begin{array}{l}
\heartsuit \,\,\heartsuit \\
\heartsuit \,\,\heartsuit \\
\end{array} \\
\end{array} \\
\end{array}\]](misc/16.gif)

This section outlines the process for creating a Cartesian plane
like in example (c) above.
-
Open a new MathType equation window.
-
From MathType's Format menu, select Define Spacing.
-
Set
Line spacing to 100% and Operator spacing to 1%. Click OK.
Note: Don't forget to reset these values when you are done or
subsequent equations will not be formatted correctly. Better yet, why not
save these settings as a MathType Preference file? If you are not familiar with
Preference files, refer to the MathType documentation.
-
Type y and press ENTER to insert a new line
into MathType.
Select Align Center from MathType's Format menu.
-
Insert the Upwards Arrow from MathType's Arrows
palette and then press ENTER.
-
Type "-x".
-
Insert a Leftwards arrow from MathType's Arrows palette.
-
Select the "Variable-size matrix or table" template from MathType's
Matrix templates palette:
Decide how large you want to make the grid. You can construct grids up to 32×32.
In this example, we will make a 8 by 8 grid.
-
In the Matrix dialog,
set the Rows and Columns to 8 so the Matrix dialog appears as:

-
After defining your matrix, begin filling in the
partition lines. There are four kinds of partitions lines to choose from: None,
Solid, Dashed, and Dotted. Clicking between the gray boxes in the grid will
insert lines. Subsequent clicks will cycle through the four kinds of lines. In
this example, we use solid lines for the x- and y-axes and the outer border, and
dotted lines to form the squares in the plane. Set your partition lines so they
appear as below:

-
Click on OK to create the matrix in the MathType window.
We will correct the alignment later.
-
Move cursor to the right of the matrix.
-
Insert a Rightwards arrow.
-
Type x and then press ENTER.
-
Insert a Downwards arrow from MathType's Arrows palette
and then press ENTER.
-
Type -y.
-
Type the axis coordinates into the cells of the matrix.
After inserting them, select each one and choose Subscript from MathType's
Size menu to reduce their size.
-
In the cells beneath the 1, 2, and 3 labels on the positive
x-axis, change the color to white and enter −2. The purpose of
this step is so the width of each cell's contents will be the same. The −2's
will still be visible in MathType, but not in your document. All the elements of your
Cartesian plan have now been entered, and it should appear as below:

-
To align the points along the axis, arrows,
and axis labels, you will need to nudge the arrows and labels
into position. (If you are not familiar with nudging, refer to the MathType
documentation.) After the appropriate nudging, you will end
up with a fully labeled grid like the one below:

Creating number lines
Number lines can be constructed in MathType through the use of nudging, tabs,
and the "double-headed arrow with upper and lower text slots" template.
This section outlines the process for constructing the number line shown
below:

-
Open a new MathType equation window.
-
Under MathType's View menu, make sure the "Show All" option is
checked so you can see tabs and blank spaces.
-
From the Format menu, select Define Spacing and set
Denominator depth to 150%.
Note: Don't forget to reset this value when
you are done or future equations you build will not format correctly! As
an alternative, you can save this setting as a MathType Preference file
named "Number Lines". If you are not familiar with Preference files,
refer to the MathType documentation.
-
Click OK to return to MathType's main editing
window.
-
Insert the "double-headed arrow with upper and lower text
slots"
template:

-
In the upper slot, type in a vertical line character,
|, which is Shift+\
on your keyboard.
-
Insert a tab after the vertical line character by pressing
CTRL+Tab. You should see the following in your MathType
window:

-
Repeat steps 6 and 7 five times, to alternate five more
vertical lines and tabs, then add a final vertical line, so that you have
the following:

-
In the lower slot, type in your number range starting with
-3 following
each number with a tab, so your number line appears as:

-
Select all the vertical lines and tabs in the upper slot
of the "double-headed arrow with upper and lower text slots" template and
nudge them down until
the vertical line characters are bisected, marking the coordinates on your
number line as below:

-
Nudge the negative coordinates to align them with the
vertical bars,
and you should have the finished number line below:

The tab marks are only visible in MathType when the Show All
option is turned on. If you turn off the Show All option or insert the number
line in a document, it will appear as:

You can increase or decrease the space between coordinates by inserting your own
tab stops rather than using MathType's defaults. If you are unfamiliar with
MathType's options for setting and using tabs, refer to the MathType
documentation.
