I received an interesting request from a user that deserves sharing. The user requested a visualization showing the curve of a normal distribution of data points. Now, just to be clear, a visualization that shows the distribution of data points is a histogram, which looks like this:
The histogram might vary a little bit if you change the number of bins being used, but it always has the continuous value along the X-axis and the (Row Count) on the Y-Axis. However, the user didn’t want to see the bars of the histogram, just a curve that represented the histogram, which would look like this:
This type of visualization is simple and easy to create in Spotfire using the following steps.
BAM! Done! The Gaussian Curve fit is the normal distribution and represents the histogram as a curve. If you combine the curve and the histogram, it looks like this:
In the end, Spotfire had the functionality to quickly and easily meet the user’s needs!
