Crude oil price is in Dollars per Barrel while the rest is in Shillings per litre. The graph is meant to show the trend not the exact data. Hence it is very accurate. The crude oil prices have been reducing steadily over the months, while the petrol prices in the country have been increasing. Other than for a slight increase in January, Kerosine prices have been decreasing ever since. Diesel prices have been stable all through with almost insignificant changes in price.
