Vertical bar chart
Sometimes called a column chart or a bar graph. The x-axis scale labels the bars rather than being a numerical scale of values as on an x-y plot.

x-y plots are used to plot one varying quantity against another. (Note that data points are joined directly without trying to smooth the data to produce a smooth curve.)
