The bar chart displays the information about how public transport was used during the period between 2012 and 2015. The bar lines are in different colour, each colour indicates the type of transport.
Overall, bus was the most stable and it line are showed on the chart by yellow colour. For instance, when the bus factor had small falls and slow increases, the train’s one was on the top in 2012, but it plummeted in 2013 just around for 70% and after this fall during the 2014 and 2015 it leveled out and became more stable.
Apparently, the most succsessful line chart belongs to tram’s one, it had the smallest factor in 2012 but it slightly increased by years approximetly from 20% to 95%. In contrast to bus line, tram’s graph has never had falls and waves. The peak for tram was in 2015 when the percentage of using it was about 95%, at the same time bus and train were neraly on the same level and their line in 2015 roughly remains about 60%.
