Bar charts are a standard way to graph discrete variables. Each bar represents a distinct value, and the height represents its proportion in the entire sample.

Can bar graph be continuous?

Bar and line plots are commonly used to display continuous data. This is problematic, as many different data distributions can lead to the same bar or line graph. Nevertheless, the rarely used scatterplots, box plots, and histograms much better allow users to critically evaluate continuous data.

Is a bar graph continuous or categorical?

Histogram: Histograms, similar to bar graphs, use rectangular bars whose heights correspond to frequency. However, bar graphs plot categorical data and have gap between each bar, whereas histograms plot numerical data and are continuous (no gaps).
