One Data Filter .

The volcano plot is used to determine the deviation in the proportion of outliers at each site from the proportion of outliers at all of the other sites. The x -axis represents the difference in proportions for measurements that are considered outliers between the site and the reference set (all other sites).in the proportion of outliers at each site from the average proportion at all of the other sites.
You can mouse over points of interest to see their labels or select points by dragging a mouse rectangle over them (as shown above). Selected rows are highlighted in other plots and you can also then click on various Drill Down Buttons for further analyses on those specific sites. For example, if you click the Out lier Bar Charts ( ) drill down, the following window opens with comparisons of sites 3 and 40 with all sites not site 3 or 40, respectively.
In these plots, 0 represents findings that are not outliers and 1 represents findings that are outliers. Both sites have an excessive number of outliers for QRS Duration.
