Notes
Here, we show two possible applications of the arrows plot style. In the left panel, we plot a map of fluid flow around a vortex core, the dotted circle showing the outline of the vortex core. The source for this is a datafile mapping fluid velocity as a function of position. In the right panel, we show a series of datapoints before and after some correction factor is applied to them, showing how the data are moved in the process.
