This graph shows the changes in the percentage of TV viewers and that of radio listeners out of the whole UK population over 4 years within a day. Both lines indicate the general trend of a fall after rise.
The proportion of TV viewers first rises from 3% at 6:00am to 10% at 8:00, which is followed by a basic leveling-off until 12:00 at noon, where we can see a constant increase to 50% at 8:00pm, the peak. Subsequently, after a sharp decline from 8:00pm to the midnight, the number keeps falling back to 3% at 6:00am next day morning.
In the percentage of radio listeners, there is a fast rise from 5% at 6:00am to 30% at 9:00am and then a continuous decline back to the starting point next morning,

This graph illustrates changes in the amounts of beef, lamb, chicken and fish consumed in a particular European country between 1979 and 2004.
In 1979 beef was by far the most popular of these foods, with about 225 grams consumed per person per week. Lamb and chicken were eaten in similar quantities (around 150 grams), while much less fish was consumed (just over 50 grams).
14
However, during this 25-year period the consumption of beef and lamb fell dramatically to approximately 100 grams and 55 grams respectively. The consumption of fish also declined, but much less significantly to just below 50 grams, so although it remained the least popular food, consumption levels were the most stable.
The consumption of chicken, on the other hand, showed an upward trend overtaking that of lamb in 1980 and that of beef in 1989. by 2004 it had soared to almost 250 grams per person per week.
Overall the graph shows how the consumption of chicken increased dramatically while the popularity of these other food decreased over the period.
