Best fit data analysis will be more useful - Biostatistics - http://snre.umich.edu/cardinale/wp-content/uploads/2014/07/Zimmerman-Cardinale-Oikos-2014.pdf
One of the most important features of spreadsheet processors is the graphical representation - in the form of a diagram - of the numerical data present in a certain area of the spreadsheet. The graphical representations better illustrate the relations, the tendencies, the anomalies that are established between the data, being easier to visualize and interpret than the simple tabular presentation of the studied figures.
Graphical representations under Excel are generated based on an analysis table that is a well-defined and delimited field of the spreadsheet, which in turn contains numerical data organized in data series.
When working with quantitative (statistical) data, analytical software will be very useful.
The quantitative analysis program can be used to generate tabulated reports, charts and graphs of distributions and trends, as well as to generate descriptive statistics such as means, medians, modes and frequencies, in addition to more complex statistical analyzes such as regression models.
Excel is better for doing graphs, as there are several graphing options that might be better for illustrating curves on graphs. As for statistical analysis programs, they are better for analyzing data, whether obtained from scientific experiments or from the studied community, where we can choose the mathematical model, analytical methodology, and/or statistical design most appropriate to analyze the characteristics and factors that affect them. Thus can extrapolate the data and obtain useful results in the research conclusions.
Even though Excel is the best platform for creating graphs, now the trend has been changed. by using the softwares PAST, Origin Pro or NCSS, you can plot your graph according to your objectives.
