Bar Plots are easy to populate through the drag-and-drop functionality in FCS Express 6. You can drag gates, statistical tokens, or freetext to create bars on a Bar Plot that has been inserted on your layout.
When populating a Bar Plot by drag-and-drop, the following attributes can be controlled:
•The specific statistic relating to the gate to be plotted.
•The position of the new bar relative to existing bars.
•The addition of new overlays to the Bar Plot.
•The X-axis label for each bar.
See the figures and steps below to learn how to populate Bar Plots by drag-and-drop.
After inserting a Bar Plot, dragging and dropping gates onto it will cause the Edit Statistic dialog to appear. The specific statistic relating to the gate can be chosen for plotting (e.g., "% of Gated Cells" in Fig. 11.32).

The result of dragging and dropping a gate to a bar plot and choosing the desired statistic in the Edit Statistic dialog is shown in Fig. 11.33.

A second gate can be dragged to the Bar Plot to open the Edit Statistic dialog, from which a statistic for the second bar is chosen (Fig. 11.34).

Statistical tokens or freetext from default statistics windows or text boxes on your layout can also be dragged directly to Bar Plots. In this case, the Edit Statistic dialog will not appear. In the example below, the selected "CD8, % of gated cells" statistic is dragged to the second position, to form a new bar between the existing two (Fig. 11.35).

To add an overlay, drag the data source toward the Bar Plot and drop it below the axis (Fig. 11.36, ); the overlay will be overlaid onto the first bar.
To add subsequent bars, drag the data source toward the Bar Plot and drop it to the right of the intended bar of the first overlay (Fig. 11 (below) ).

To add a descriptive X-axis label for each bar:
1.Click on the label
2.Enter freetext or tokens (using the button) into the label editor bar. Fig. 11.37.
3.Click the green check mark in the label editor bar or hit Enter on the keyboard to accept the change. In the example below, the label for the second bar has been edited to "population 2".
