Intuitive, easy to use and does the job

Interestingly, the plugin does not requires me to specify x and y axes, but somehow it figures out. I guess user would have to put the x axis values in the first column and y axis values in the following columns.

I’ve tried several charts-making plugins. I would have to say this is exactly the one I needed. There are some other charts-making plugins are quite popular, but you can barely do anything with their free versions.
