I assume that you have a data set, which is a log of experimental results, and for each event you have recorded an outcome. I supposed you would not be asking this question if the outcome was categorical and you'd be plotting a column chart. If the outcome is a continuous variable, you can if course plot its distribution and / or density plot. However, if you wanted to visualise the probability density, you could either generate a new attribute which can be scaled to add up to 1, use an aggregate operatorbto find the total of all your outcomes, and you can also use a Pareto chart to visualise the distribution of your outcome probabilities vs cumulative distribution of these values.
