Analyte Charts and Tables
57
When you select the Bar Graph icon, a Legend column appears in the analyte
table. Each selected analyte corresponds to a color. These colors match the
colors of the bars in the bar graph. You can also display a legend in the
analyte charts and tables pane by clicking the Legend checkbox in the
toolbar.
When you hover over the bar, an annotation appears with information about
the analyte including the mean value for the analyte, the P-value, fold change,
and the statistical method used.
On each bar, an error bar plots one standard error from the mean.
