Concentration Histogram and Total Concentration
Popup Menus
The menu items for the popup menus for the Concentration Histogram and
Total Concentration windows (Figure 5-38) are the same except
Concentration Scale or View Boundaries cannot be selected from the Total
Concentration Graph popup menu. This is because the data in the Total
Concentration Graph window is always auto-scaled and represents totals
for all channels. You can only change the scale type in the Total
Concentration Graph window between logarithmic and linear using the
toolbar button.
