Retrieve CSV from URL #24

Greatly enjoying the IDE for gnuplot iterations, however how do I fetch data from a URL?

For example https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/01-22-2020.csv ?

I know how it works in python roughly, but not this kernel.

See how the %%shell block magic is used in the example notebook, https://github.com/has2k1/gnuplot_kernel/blob/master/examples/gnuplot-kernel.ipynb .

You can use wget or curl or any other command that downloads files.

Be good if you could have an example where the curl stdouts into some variable that I can plot off the bat! Thanks again!

I don't think you can download into a variable. You have to download to file then use the file in gnuplot.

Yes, you're right, it needs to be in a file to be used. Thank you!
