Scatter #17078/HEAD / v10
Tags:  not added yet

DSL Element scatter{}

Scatter plots show the relationship between two variables by displaying data points on a two-dimensional graph. They are useful in the early stages of analysis when exploring data before actually calculating a correlation coefficient or fitting a regression curve. For example, a scatter plot can help one to determine whether a linear regression model is appropriate.

The scatter element of an analysis provides for an easy creation of a scatter plot:

    ...
    analysis {
        scatter {
             x(file:"%last/out1.csv", column:"basin_cfs")
             y(file:"%last/out1.csv", column:"runoff[0]")
        }
        ...
    }
    ...

Provide x and y axis information accordingly. The setup above indicates the correlation of a simulated and observed property such as runoff
