Have you ever wondered how your data is distributed? Would you like to get more statistical information and even detect outliers?
Then you might like this new control. With the new Histogram control, visualizing data distribution has never been easier. Select a few tags, specify the number of bins you want, and you’re done!
A histogram is a graphical representation of the frequency distribution of cardinally scaled features. It requires dividing the data into classes, which can have a constant or variable width. The height of each rectangle then represents the (relative or absolute) frequency density, that is, the (relative or absolute) frequency divided by the width of the corresponding class. The histogram can be easily added to a PI Vision display by dragging and dropping a PI attribute or PI tag.
