Line plot areas

[kentatanaka]

Hi again, I’m studying KNIME Analytics.
I would like to know how to obtain areas[S1, S2, S3, S4] under line plot.

Thanks a lot.

@kentatanaka maybe you can adapt this approach:

Area under a curve.

@Gimli OK I hope I got what you want. I converted the Python code from two Stackoverflow threads (1, 2) into a small KNIME workflow. You might want to check if you could adapt that. You would enter the data and the variables and the numeric borders [image] The lower part of the workflow would just use the x-axis min and max as a default. You might be able to tweak the design of the y-axis. [image] kn_example_python_numeric_integral.knwf (341.2 KB)
