histograms are pictoral representations of continuous variables, where;
the x-axis is the continuous variable
and the y-axis is the frequency density

histograms and bar charts are closey related
. in a histogram the frequency of the data is shown by the area of each bar ( in a bar chart the frequency is shown by the height of the bar.)
.histograms have bars or columns, whose width is in proportion to the size of the group of data each bar represents, the class width, so the bars may have different widths ( in a bar chart the widths of each bar are usually the same.
. the vertical scale is labelled ' frequency density'. ( in a bar chart the vertical scale is the actual frequency.)
Histograms can only be used to show continous data which is numercial and grouped.

i hope this helps.
