Plot Single/Combine All Wells

Petra can either plot the log data points from a single well or from multiple wells in aggregate. To switch between these two modes, select Wells>Plot Single Well and Wells>Combine All Wells. Note that showing multiple wells will remove the curves displayed on the right side of the screen after all, with data points from multiple wells, which curves would you show?
