Line Graphs

Line Graph: a graph that shows information that is connected in some way (such as change over time)

You are learning facts about dogs, and each day you do a short test to see how good you are. These are the results:

Table: Facts I got Correct
Day 1 Day 2 Day 3 Day 4
3 4 12 15

And here is the same data as a Line Graph:

Line Graph Example

You seem to be improving!

You can create graphs like that using our Data Graphs (Bar, Line and Pie) page.

Or we can draw them ourself!

Let's draw a Line Graph for this data:

Table: Ice Cream Sales
Mon Tue Wed Thu Fri Sat Sun
$410 $440 $550 $420 $610 $790 $770

And let's make the vertical scale go from $0 to $800, with tick marks every $200


Draw a vertical scale with tick marks


Label the tick marks, and give the scale a label


Draw a horizontal scale with tick marks and labels


Put a dot for each data value


Connect the dots and give the graph a title

Make sure to have:

  • Vertical scale with tick marks and labels
  • Horizontal scale with tick marks and labels
  • Data points connected by lines
  • A Title
