Plotting multiple curves in one plot through a cycle

Hi all!

I'm new to both knime and R so sorry if my question is a bit silly.

I've created a simple workflow to:

1) open multiple file and join them togheter with only one x axis (PPM) and several y axis (the name is created through the cycle from the file location)

2)plot each indivual x and y couple and save them to a specific folder (with a R snippet)

3)plot all the curve in a single plot (with a R snippet) with different line style

 

The last point unfortunately is not working and I don't know why.

Any help will be appreciated :)

Cheers,

Michele

Hi Michele, 

With the release of KNIME 2.10, we now have a couple of metanodes which demonstrate how to do something similar to what you ask.  If you have a look at the Grouped Scatter Plot (ggplot2) metanode and change the geometry inside the qplot by adding: geom="line", you should be able to generate something like what you are looking for.  

Please report back and let us know if this works for you.

Regards,

Aaron
