Histograms are often used in geography fieldwork to plot the frequency of pebble long axes, with axis length ranges (e.g. Bihistograms are a very useful way to compare skewness and outliers for two data categories. Each half of the bihistogram represents a different category and can be back-to-back on opposite sides of either the y-axis or the x-axis. Choose the range or interval that best fits your data.īihistograms, made from two histograms in opposite directions, can be created by entering negative and positive data for the same interval values. A histogram plots continuous data showing the counts within ranges or intervals. Barcharts are used to show counts against discrete categories. Histograms are similar to barcharts as ways to display counts of data. Negative values may be entered as bin data to make bihistograms. The bars can be oriented horizontally or vertically. It constructs evenly spaced bin widths, so the height of a histogram bar indicates frequency (counts). This histogram constructor creates histograms and bihistograms.
