    Rename `valid_index` to `within_grid`.

    tonysyu committed
    `valid_index` suggests that inputs are integer, which is not true.

    Return collection of streamlines from `streamplot`.

    tonysyu committed
    Previously, `streamplot` just returned a dummy LineCollection so that colorbars and legends were properly set. Bonus: moving the creation of LineCollection objects out of the loop boosted the speed by about 10%.

    Remove copyright notice.

    tonysyu committed
    As Tom Flannaghan suggested in GitHub discussions, the copyright notice was removed from streamplot.py. Added attribution to CHANGELOG.

    Change handling of masked arrays.

    tonysyu committed
    Instead of changing masked values to NaNs, change NaNs to masked values.
  2. @tonysyu

    Add support for masked arrays.

    tonysyu committed
    Note that masked arrays are converted to float and filled with NaNs. Filling integer masked arrays with zeros would also work, but would give incorrect results in some instances.

    Fix streamplot to work with colorbar.

    tonysyu committed
    Streamplot no longer returns an arrow patch and, instead, only returns a dummy LineCollection.

    Add streamplot function to pyplot.

    tonysyu committed
    As a temporary fix, streamplot returns the last plotted streamline and arrow for use with colorbars and legends. Instead, all lines should instead be grouped into a single LineCollection, and all FancyArrowPatches should be grouped into a patch collection.

    Remove integrator parameter for streamplot

    tonysyu committed
    * RK12 is 1.5--2x faster than RK4 and RK45 produces visually-similar results.
    * Remove implementations of RK4 and RK45.

    Remove `Terminated` exception.

    Fix bounds checking.

    tonysyu committed
    Checking that the coordinate less than the array Nx/Ny does not work when the coordinate is float (e.g. it can be between `Nx` and `Nx - 1`).
  4. @tonysyu

    Add improvements from Tom Flannaghan.

    tonysyu committed
    * Add faster adaptive-step algorithm (RK12) to replace RK45 and RK4 integrators.
    * Fix arrow placement when streamline is only 2 points.
    * Calculate stepsize based on grid size.
