All period-over-period charts include only two fields, one for an x-axis column (which will always include time period data) and one for a y-axis column (which will always include value data). For information about applying columns to a chart, see [Applying DataSet Columns to Your Chart](/s/article/360043428713 "Applying DataSet Columns to Your Chart"). The following table lists and describes all of the available period-over-period charts. You can click a thumbnail image to see a full-sized version of that image. For information about building all of the charts in this table, see [Period-over-Period Charts](/s/article/360042924834 "Period-over-Period Charts").
