7.4. Log Scale in Output Graphs

Applies to: @RISK 6.2 and newer

Beginning with @RISK 6.2, you can display the x and y axes of most graphs in logarithmic scales, using any of these methods:

Tick the "Log" box on the X-Axis or Y-Axis tab of the Graph Options dialog.
Right-click the graph and on the context menu select Log Scale X-Axis, Log Scale Y-Axis, or both.
In VBA, you can use the RiskGraph.XAxis.LogScale and RiskGraph.YAxis.LogScale properties.

Generally, graphs with numeric scaling support log scaling. Here are the major exceptions:

Histograms with some data values less than or equal to 0. However, you can switch to a cumulative display (S-curve) and get logarithmic scaling.
Histograms in probability density format. (Interpretation of these would be confusing.) However, histograms in relative-frequency format can be displayed on a log scale. If you are using the default Automatic formatting, and you select a log scale, @RISK will automatically change the histogram to relative-frequency format.
The x axes of tornado graphs and summary graphs. (A summary graph may appear to have a numeric x axis, but actually those numbers are just treated as labels.)
