Create
a Graph lets your child make a broken-line graph using appropriate
intervals for the range of data collected.

To use Create a Graph, type in the title of
the graph, and the horizontal and vertical titles. Calculate the number
of points needed for the graph. Type the name, value, and colour. Choose
the 3-D option, graph direction, and graph size. Click 'Create Printable
Graph' to see the results.

Line
Graphs is an interactive activity that allows your child to use
a broken line graph to identify trends.

To use Line Graphs, click the 'Data' button and select a topic. A line
graph appears on the workspace. Click the button with two yellow bars
to see the data in chart form. To change the data using the pre-selected
topics, click the red square on the graph and drag it to another location.
The data in the chart will then reflect the change on the graph. To change
the range on the vertical axis, click the numeric button, beside the 'Data'
button. Use the up arrow to increase the range on the y-axis, and the
down arrow to decrease the range on the y-axis. To change the range on
the horizontal axis, click the numeric button within the chart. Use the
up arrow to increase the range on the x-axis, and the down arrow to decrease
the range on the x-axis.

To enter original data, click the 'Reset' button. Enter the title of
the graph, and label the x and y- axis. Select points on the horizontal
axis and drag them to the desired location. The data will be reflected
on the chart. Click on the button with the squiggly red line to show
data in decimal format less than the number one.
