Split on whitespace for compatibility with gnuplot

In which part of the interface would this feature applies?

[x] 1. Load your data [ ] 2. Choose a chart [ ] 3. Mapping [ ] 4. Customize [ ] 5. Export

Is your feature request related to a problem? Please describe. This may be a problem with my expectation, but I'm searching for a tool that's easier to use than the standard gnuplot. I hoped RAWGraph was an option.

I have a simple 170 line time-value file that I previously used in gnuplot which I tried to load in RAWGraphs.

To my surprise and confusion, I found no option to split columns on whitespace, the default in gnuplot and thus a common output format.

Describe the solution you'd like Simply an option to split on whitespace, not just tabs.

Describe alternatives you've considered One alternative is of course to pre-process all my data locally to fit this tools input format.
