Curves for Groups
This chart displays three different groups of nodes for each of which you can generate a histogram. Just tick the corresponding checkboxes of the groups in the "Histogram" column of the table on the left and click on the button "Fit histograms" in the top right corner of the screen. The histograms add up the workload of the nodes of a group and mark it by a black line. In addition, they display a capacity curve, i.e. the amount which can be worked off at maximum. Overloads occur where the workload exceeds the capacity. The histograms allow to identify them immediately: they mark overloads by a hatched pattern and a darker color. You can avoid overloads by moving nodes (drag&drop). Beside, you can modify the size of the chart by clicking on the arrow buttons around the top left corner of the chart.
