03. Data (and the software)

To draw a dot plot there are just three things you need to do.

1. Select the x-variable… this is your time series variable that will be on the x-axis, in this case it’s ‘Time’.

2. Select the y-variable… this is your actual data, in this case it’s ‘Arctic’.

3. Select the graph type… for this we want the ‘time series re-composition’.

You then just need to check the graph title and axis labels to make sure they are appropriate (include units where necessary) and add press update graph to save any changes you've made.

To copy the graph just right click and press copy image, or to save press ‘Save Image As’ or whatever your device says that is similar.

Note: If you want to identify the extreme points, if you click the ‘Point Labels’ checkbox this will add little numbers next to the points that correspond with the point id.

To get the seasonal effect graph just change the graph type to ‘time series seasonal effects’

Note: you will need to change the x-axis title to reflect if it is monthly or quarterly (or something else).

The final graph we need is the forecast graph.

To get the visual output you just change the graph type to ‘time series forecasts’

You will also need the text output of the predictions which you can get by clicking on the tick box below the graph.
