In 2015 sales of all 3 types of fast food increased dramatically.
This is a common error. Unfortunately there is no information about change in 2015, only from 2005 to 2015:
- Between 2005 and 2015 sales of all 3 types of fast food increased dramatically.
If you are not specific about the time frame then your reporting of data will be inaccurate and you will receive a low score in IELTS for Task Achievement.
Before you write, decide exactly when the change happened and design a suitable time expression. These are the most commonly used:
- from time 1 to time 2
- between time 1 and time 2

If the time in the graph was in the past, what tenses should I use? past tense or present perpect?
If the timeframe is past and finished, then you need past simple tense 😄
then, when we use present perfect? Is it ok if I write like this : The number of AAS awardees has declined between 2014 and 2015.
In the context of a chart like this, use present perfect to describe a change that started in the past and is still happening. If there was a third set of columns on the chart relating to 2016 (the present), then you could use present perfect to describe a change that began in the past and is included in the present.
