Chart Examples
After you perform these steps, the combo box displays the month names and places the index
number of the selected month into cell F1. The formulas in row 2 display the appropriate data,
which displays in the chart.
This example is available on the companion CD-ROM. The filename is chart from
combo box.xlsx .
Plotting mathematical functions
The examples in this section demonstrate how to plot mathematical functions that use one
variable (a 2-D line chart) and two variables (a 3-D surface chart). Some of the examples make use
of Excel’s Data Table feature, which enables you to evaluate a formula with varying input values.
A Data Table is not the same as a table, created using Insert
Tables
Table.
Plotting functions with one variable
An XY chart (also known as a scatter chart) is useful for plotting various mathematical and
trigonometric functions. For example, Figure 17-13 shows a plot of the SIN function. The chart plots y
for values of x (expressed in radians) from –5 to +5 in increments of 0.5. Each pair of x and y
values appears as a data point in the chart, and the points connect with a line.
Excel’s trigonometric functions use angles expressed in radians. To convert degrees to
radians, use the RADIANS function.
The function is expressed as
y = SIN(x)
The corresponding formula in cell B2 (which is copied to the cells below) is
=SIN(A2)
