This function grapher can draw one or more functions (on a grid).
To enter the functions:
select the functions expressions separated by commas then click on Graphing Function
or
click on Graphing Function and enter the expressions in the dialog box
Example :

Note: read the Math Expression rules.
A dialog box opens:

Click on Tracing Range tab, then click on the tracing range checkbox to display the textbox to enter the tracing range (one or two intervals).
Click on the Tangent tab to enter the points where a tangent to the function curve will be drawn.
Example: x=1 name of the point:A right and left tangent ; to enter more than one point, enter x=-1 ; 2 then name of the point that will be displayed: A ; B
Click on the Hash tab to define an area the of plane to hash and to choose hash type:
Area of the plane:
y>f(x) or x>g(y) (according to function definition y=f(x) or x=g(y))
y<f(x) or x<g(y) (idem)
surface of the integral sum : 0<y<f(x) (f(x)>0) and f(x)<y<0 (f(x)<0) (respectively for x=g(y))
f(x)<y<g(x) then enter f(x);g(x) in the function definition textbox.
Hash type:
polygone (you can change background color and etc...).
lines: set of lines parrallels to the defined line:
default line is y=x and the space between two line is 0.5
Check Display on a grid.
If left unchecked, the functions will be graphed without gridlines.
Grid type:
a centimeter grid, a half-centimeter grid, a millimeter grid, a two millimeter grid, axes graduated in centimeters, axes graduated in millimeters.
Choose if you want the fifth unit line to be heavier (like on a graph paper)
Check the box if you want to display the x-values and the y-values.
Then choose if you want to display the x-values and the y-values on the bottom and left side, respectively, or along the axes.
Again choose the step of x-values and y-values between two consecutive graduations (by default every centimeter).
If this value is not a multiple of the scale, then a line of axis-width will be drawn for every value.
Display O,i,j and suppress graduations between 0 and 1, suppress graduations except 0 and 1
Enter x-scale and y-scale:
1 cm represents 1 unit : from -4 to 4, the interval length will be 8 cm on the drawing
1 cm represents 2 units : from -4 to 4, the interval length will be 4 cm on the drawing
1 cm represents 0.5 units : from -4 to 4, the interval length will be 16 cm on the drawing
Graphing range
Enter xmin and xmax
Enter ymin and ymax
You can use expressions in the xmin, xmax, ymin, ymax values such as pi/2 , 2/3, etc..
The function curves can go outside these intervals, but only the range will be traced.
The x or y range is rounded to the nearest 1/10th of the scale value :
Ex: from -4.25 to 3.14 with 1cm representing 1 unit will be considered as from -4.3 to 3.1
Increment: dynamic.
Options:
Display min and max range value on grid.
Display graduations as fractions.
Display unit name on x-axis and y-axis:
Example: U[AB] displays U with AB in subscript
Example: f{2} displays f with 2 in superscript
In Word equation editor mode (EQ button is grey), the graduations are displayed using Word equation editor in the size specified (font is Calibria Math).
In Field code mode (EQ button is blue or yellow), the graduations are displayed directly in the font and size specified (field codes are used for fractions).
In the following example we have:
A centimeter grid with every fifth line heavier.
x-values and y-values displayed on the axes.
x range : between -3 and 3.4 x scale: 1 cm represents 1 unit
y range : between -1.3 and 5 y scale: 1 cm represents 1 unit
Display : x unit name(x) and y unit name (y) + display opposite unit names
Result:

Example: when the x graduation is not a multiple of the x-scale:
Graphing sin(x) and cos(x) from -2p to 2p with x-graduation every pi/2:

Note: checkbox Display same number of decimal is checked so that instead having 1 , 1.25 , 1.5 we have 1.00 , 1.25 , 1.50...
Note: the checkbox Fraction displays x-axis graduations as fraction (of pi here)
Result :

Example with hashed area between two function cruves:
Graph 1+x²/2 and 3*sin(x) defined on -2 , 2 on a grid graduated every cm from -3 to 3 with hashed area of f(x)<y<g(x) :

Result :

When typing x+0.25 pas 0.5, the hashing lines are from the family of lines x+0.25+k*0.5.
Note: in Options : change grid line size and color, axis graduation font name and size, whether to draw the axis x=0 et y=0 with 1/2 cm supplementary on each side, and so on... The changes are saved and kept when you quit Word.

The plotter can draw from one to three sets of points:
- x1, y1, y2 for one x-value, one or two y-value
- x', y'1 for one x-value, one y-value
For each set of points (x,y), you can choose to draw :
- the points
- link the points with lines
- draw a parabolic smoothering
- draw the Bezier smoothering curve (based on middle points)
- draw the spline (N order) smoothering curve
- draw the linear regression line y=ax+b (not x=cy+d)
Prepare the data in a Word table:
The first row contains the set x
The second row contains the set y1
The third row contains the set y2
The fourst row contains the set x'
The fifth row contains the set y'1.
Note: if the first column of the first row contains 'x' then this column will be deleted from the data.
Example: pH measured while titrating 10 ml of acetic acid 0.1M and while titrating 10 ml of ammonia 0.1 M

Place the cursor in the table, then click on the Plotter button.
(each set of points can have different number of points)
A dialog box is displayed:

The sets of points are displayed in the dialog box separated by commas.
Facing x, we find the data of volume of strong base used for titration while titrating the acetic acid
Facing y1, we find the measure pH, the choice for the plot (plus, circle, cross, square), and the kind of curve to display
Facing y2, we find ,,,,,,,,,,,,,, (empty line in the table) that shall be deleted.
Facing x', we find the data of volume of strong acid used for titration while titrating ammonia
Facing y1',we find the measure pH, etc...
This dialog box is quite similar to the function graphing dialog box.
In the example, the domain of the x-interval is from [xmin=0 , xmax=20] with an x-scale of 1 cm representing 2 units
and the range of the y-interval is from [ymin=0 , ymax=14] with a y-scale of 1 cm representing 1 unit.
More over you can graph functions and draw points A(x,y) and vectors AB(0,0,1,1)
- add one or more functions f(x);g(x);... that will be drawn
- add a set of points and vectors
Result:

Enter the maximum value if required. Enter the minimum value if required.
For example:
Input 1 : Sinusoidal : amplitude 2 : period 3
Input 2 : Sinusoidal : amplitude 2 : period 3 : phase shift 1
Result:

Example 2 : square signal integration
Input 1 : square : amplitude 3 : period 3 : high period 1.5 (low period = period (3) - high period (1.5) = 1.5)
Input 2 : triangle : amplitude 2 : period 3


Example 3 : capacitor load-unload
Input 1 : square : amplitude 1.5 : period 3 : offset 1.5
Input 2 : load/unload : amplitude 3 : period 3 : inverse of delay 1
