Both samples were creted with SAP Analytic Cloud.
Work sample 1:
As basis for the first example a chart of statista, which shows the car sales in china, divided by the countries of origin of the car brands.
Due to the visualization as stacked bars and the chosen layout on the x-axis, the viewer is missing important information such as the comparability between years and countries.
Work sample 2:
As basis for the example a chart of statista, which shows the used-car sales in the USA in the years 2020 and 2021.
Due to the chosen visualization as a column-chart the seasonal fluctuation of car sales suggests a negative trend. Additionally there is no comparison over years possible due to the selected x-axis view.
Work sample 1 With the help of small multiples and the new layout on the x-axis, both can be analyzed. Comparisons over multiple years as well as comparisons over different countries of origin. Additionally and analysis of variance was added. Thereby the consumer gets an overview of the sales figures in total. The axis between sums (left) and single markets (right) weren't synchronized, due to a better readability of the different charts.
Work sample 2 While the periodic values show the monthly values and the rising lines show the cumulated values, the additional lines on top of the chart (which generate the typically z-shape) show the "Moving Annual Total" (MAT) - a seasonal-adjusted visualization of the data. On the contrary of the statista-chart we see, that we don't have a negative trend of used car sales.
