You can fit your data using the exponential distribution in the Distribution platform. Use the Quantiles command in the red triangle menu of Fitted Exponential and specify 0.005, 0.5, and 0.995 for the desired probabilities. The estimated quantiles can then be used for user-specified control limits. Right-click in the Individuals chart in CCB and select Limits > Add Limits. Enter the quantiles here.
