Bar graphs can be used for nominal and ordinal scales of measurement.  They are used to display categorical or discrete data where the categories have no inherent order, or where there is an order but the distance between scale values is not meaningful. In both nominal and ordinal scales, individual observations can only be classified or ranked but not measured numerically, making bar graphs a suitable visual representation for these types of data.
