Line Graphs for different variables

[Ali Taleb]

Dear All,

I need to draw a graph that shows different NO2 measurements for different local authorities during different periods of time.
I generated Dummy variables for measurements by 2005, by 2010 and by 2018, for example, a local authority with NO2 measurement during a period until 2005 is 1 and otherwise 0.

example of the data set that I have

no2    localauthority    bytheendof2005    bytheendof2010    bytheendof2015    bytheendof2017    never
    Aberdeen City    1    0    0    0    0
53    Aberdeen City    1    0    0    0    0
30    Aberdeen City    1    0    0    0    0
10    Aberdeen City    1    0    0    0    0
26    Aberdeen City    1    0    0    0    0

The line graph needed is to have 5 lines, for bytheendof2005, bytheendof2010, bytheendof2015, bytheendof2017 and never on the X-axis
and on the Y-axis NO2 rates.

Many thanks

Ali
