Here you can configure risk matrix charts. One chart can be used by several risk models.
When you edit a risk chart, you can change its various properties. “X Axis Granulation” defines how many squares wide the risk chart is; “Y Axis Granulation” sets how many squares tall it is.
Once you’ve chosen a granulation, you’ll want to set Axis Ticks. These are semicolon-separated lists, one for each axis. So if your matrix is 5x5, you might set X Axis Ticks to “A;B;C;D;E” and Y Axis Ticks to “1;2;3;4;5”. Or you could use longer descriptive text like “Negligible;Mild;Moderate;Major;Severe”, or whatever is mandated by your risk model.
Right-click on a square to set its colour. Choose a predefined colour or choose Custom to get a colour picker dialog.
Left-click on a square and you can set a whole number risk value for that square.
