A block histogram lets you see the distribution of numeric values in a data set. The x-axis is divided into 'bins' that correspond to value ranges. Each item in the data set is drawn as a rectangular block, and the blocks are piled into the bins to show how many values in each range. To see the exact value of a block move your mouse over it. If you are charting more than one dimension use the menu at the bottom of the graph to choose which to show. You can also highlight a block by clicking - use control-click to highlight more than one, and click again to deselect). Highlights are helpful for pointing to particular items when you make a comment or following a particular item as you change the x-axis using the menu at bottom.
