Q. What is the difference between the 2D histogram vs Statistical histogram plot?

Q. If I do the gaussian distribution fit using both the histograms the base line of fit on both sides are not equal while doing this using statistical histogram option
whereas using the non-linear curve fitting in 2D (column histogram graph) the base line for the fit is equal?

kindly anyone give me the solution and answer for above questions and say how the data are plotted while plotting with these two options.

Hi Bharath,

A. The 2D histogram is used to get a visual overview of two variables, using a density plot and accompanying heatmap. The statistical histogram is used for a single variable. I have an example opju that looks at height and weight data.

A. The Gaussian distribution fit based on the histogram depends on the bins and frequency counts. Whereas the Gaussian distribution fit based on the non-linear curve fitting option is using the raw data. The first option, the histogram, is used to get a visual overview of your data while the second option is more accurate and should be used for your analysis.

Thanks,
Nadeesha
