I n t r o d u c t i o n
Line graphs depict fluctuations in data through ascending and descending 
lines. They serve as a tool for comparing various events, situations, and 
information.

Key Components of Line Charts
Data Series
Data presented as 
sequence of points, 
each corresponding 
to a specific value at 
a particular moment 
in time.
X-Axis and Y-Axis
Horizontal X-axis 
represents 
independent variable 
(time), vertical Y-axis 
represents dependent 
variable (numerical 
value).
Data Points
Each point comprises 
X-coordinate 
(horizontal position) 
and Y-coordinate 
(vertical position) 
values.

Understanding Line Segments and Trends
Line Segments
Data points linked by line segments, 
offering visual depiction of data's 
trend or pattern. Connected line 
implies smooth transition between 
points.
Trends and Patterns
Upward-sloping line signifies 
increasing values, downward-
sloping indicates decreasing values. 
Horizontal line signals no change.

How to Make Line Chart?
01
Choose Suitable Scale
Use data from the data-table to select 
appropriate scale for your chart.
02
Draw and Label Axes
Draw and label the scale on vertical (y-
axis) and horizontal (x-axis) axes.
03
Plot Data Points
List each item and place the points 
accurately on the graph.
04
Connect Points
Join the points with line segments to 
complete the chart.
