Making Line Graphs

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

Or you can draw it yourself!

Example: Ice Cream Sales

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

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

line graph 1
Draw a vertical scale with tick marks

line graph 2
Label the tick marks, and give the scale a label

line graph 3
Draw a horizontal scale with tick marks and labels

line graph 4
Put a dot for each data value

line graph 5
Connect the dots and give the graph a title
