CREATING A LINE GRAPH A step by step

CREATING A LINE GRAPH A step by step guide

Creating a Line Graph Using the following data we will show to draw a line graph. Time (s) Temperature (o. C) 0 10 20 30 40 50 60 -10 -5 0 10 12 15 23 It is normal to place the variable quantity, in this case the temperature, on the y-axis. Notice that the temperature ranges from -10 o. C to 23 o. C, this means that we will have to draw the y-axis to include negative values

Creating a Line Graph Temperature/Time Graph 25 Temperature (o. C) 20 15 The first co-ordinate is at zero seconds o andsecond the temperature Lastly, add a title The co-ordinateisis-10 C (0, -10), let’s again mark itwe with amark cross. it 10, -5, willthe Now repeat for all other with and a cross. Now you try an example data, draw a line to connect the points As we have seen previously, we first need to draw vertical and horizontal axes, and insert the scales, in this case there are negative quantities, we therefore need to extend the y-axis below the line of the x-axis 10 5 0 10 -5 -10 20 30 40 50 60 Next we add the x and y axes labels Time (s) Temperature (o. C) 0 10 20 30 40 50 60 -10 -5 0 10 12 15 23

Creating a Line Graph Draw a line graph of the following data showing how much weight a person lost on a diet Month 1 2 3 4 5 6 7 8 9 10 Weight loss (kg) 2 1. 7 0. 75 1. 2 . 5 . 8 1 2. 2 1. 8 0. 2
