Right-click a bar of the second histogram, then click on Change Series Chart Type. A frequency diagram, often called a line chart or a frequency polygon, shows the frequencies for different groups. However, it has a major difference when compared to the histogram: instead of having the class intervals on the horizontal axis clearly showing their upper and lower limits, a frequency polygon uses the midpoints of the class intervals. A frequency histogram is a type of bar graph that shows the frequency, or number of times, an outcome occurs in a data set.
