  • Title block

    Title block

    Closes #11.

    I wanted to understand how this library works a bit better so I had a go at writing a new block - the title block.

    I wrote it using test-driven development so there are some unit tests included too.

    I also grouped your existing comparison tests into a class.

    I tried to use args and kwargs in such a way that any type of format string can be passed, and any kwargs intended for the call to matplotlib.pyplot.ax.set_title() are specified as a separate dictionary.

    Let me know what you think.

  • blocks.Pcolormesh seems to have different behavior than plt.pcolormesh

    blocks.Pcolormesh seems to have different behavior than plt.pcolormesh

    I am not sure if it is a feature or a bug. When I was playing with the example code:

    import numpy as np
    import matplotlib.pyplot as plt
    import animatplot as amp
    
    
    x = np.linspace(-2, 2, 5)
    y = np.linspace(-2, 2, 5)
    t = np.linspace(0, 2*np.pi, 40)
    
    X, Y, T = np.meshgrid(x, y, t)
    
    Z = np.sin(X*X+Y*Y-T)
    
    block = amp.blocks.Pcolormesh(X[:,:,0], Y[:,:,0], Z, t_axis=2, cmap='RdBu')
    plt.colorbar(block.quad)
    plt.gca().set_aspect('equal')
    
    anim = amp.Animation([block], amp.Timeline(t))
    
    anim.controls()
    plt.show()
    

    I used a very coarse grid 55 instead of the original 5050, so that it is more clear. The data array Z is of size 55 at a certain time step. But the generated animation shows a grid of shape 44. It seems blocks.Pcolormesh use the value in Z as the "node" value in animation, which is different in plt.pcolormesh whereZ value is treated as the "mesh cell" value.

  • [Bug] .gif files don't loop

    [Bug] .gif files don't loop

    .gif files created with animatplot only run once through, then stop on the final frame. They do loop properly when running interactively (in a Jupyter notebook) though.

    I'm creating a gif in a jupyter notebook, using %matplotlib notebook. I save the gif, then try to open it using

    ![Ising](ising.gif "ising")
    

    This displays the gif once through, then it stops on the final frame. If I rerun the cell then it just opens a static image of the final frame.

    If I open the .gif file with another program it also stops on the final frame, so I think it's a problem with the created file.

    I've tried explicitly passing repeat=True to FuncAnimation() inside animatplot.Animation, and I've also tried using the imagemagick writer rather than PillowWriter, but the problem persists.

    A reproducible example, which is basically just this example):

    %matplotlib notebook
    import numpy as np
    import matplotlib.pyplot as plt
    import animatplot as amp
    
    # Define LxL matrix
    L = 55
    # Initialize as random spin
    M = 2*(np.random.rand(L,L)>.5)-1
    J = 1
    b = 2.5
    
    nPer = 100
    
    images = [M]
    for i in range(100):
        M = M.copy()
        for dm in range(nPer):
            jj = int(np.random.rand()*L - 1)
            kk = int(np.random.rand()*L - 1)
            dE = 2*J*(M[jj+1,kk] + M[jj-1,kk] + M[jj,kk+1] + M[jj,kk-1])*M[jj,kk]
            if dE <= 0:
                M[jj,kk]*=-1
            else:
                if(np.random.rand()<np.exp(-b*dE)):
                    M[jj,kk]*=-1
        images.append(M)
        M[:,-1] = M[:,0]
        M[-1,:] = M[0,:]
    
    fig1, ax1 = plt.subplots()
    
    block = amp.blocks.Imshow(images, axis=ax1)
    anim = amp.Animation([block])
    
    anim.controls()
    anim.save_gif('ising')
    
    ![Ising](ising.gif "ising")
    

    Also the output of using conda list to see which versions of everything I'm using:

    conda-forge package

    While this is a pure python package, pip likes to mangle conda packages sometimes. So, if someone tries to install Animatplot with a version of matplotlib < 2.2 which was installed with conda, then pip attempts to update matplotlib and butcher the environment (sometimes multiple since conda symlinks packages of the same version across environments).

    I'd like to be able to install Animatplot with conda.

  • Suggestion for xarray integration

    Suggestion for xarray integration

    A simple example showing some of the advantages of providing convenience functions for plotting xarray DataArrays. xarray integration means that you could streamline the visualisation of time-evolving data down to just a few lines, e.g.:

    data = xr.load_dataset('3d_data.nc')
    anim, block, timeline = amp.animated_plot(da)
    anim.save_gif('./xarray_imshow')
    plt.show()
    

    Although I think full seamless integration into xarray's system would be quite involved (and not something I'm qualified to do), then providing a set of convenience functions something like this shouldn't be very difficult.

    Notice there are several # TODOs in the code showing how this could be extended.

    Let me know what you think!

  • matplotlib3.3 shading=

    matplotlib3.3 shading="nearest" compatibility

    matplotlib-3.3 adds a new option shading="nearest" for pcolormesh. This PR makes animatplot compatible with that option. Now also works with shading="gouraud" when matplotlib=3.3. Don't know why shading="gouraud" still doesn't work with matplotlib<=3.2, I guess they changed something in the internals.

  • Line block tests

    Line block tests

    I added some unit tests for blocks.Line(), and extended it to also accept a 1D array input for x (the most natural format for use in xarray).

    I also tried to clarify the logic for parsing the input, and make it raise more informative errors.

    One high-level question - why allow users to input a list of numpy arrays at all? It makes the internal logic more complex and I don't really see what the benefit is. The only time a list of numpy arrays is a more suitable representation of data than a numpy array with an extra dimension is if the length of the array changes over time, but I don't know if that's actually supported by the plotting functions? Also if you do want to support do you want to keep the data internally as a list of arrays? Or is it okay to do what I did here and convert all lists of arrays straight to numpy arrays using np.asanyarray()?

    Add optional argument 'time_label' to 'timeline_slider'

    Allows you to have a timeline which has a label other than "Time". Useful for when you want to animate your data over a non-temporal dimension, e.g. space.

    Implemented as an optional argument to 'timeline_slider()', so usage looks like:

    anim.controls(timeline_slider_args={'time_label': 'x position'})
    

    Not sure if this should instead be implemented as an extra attribute on the timeline?

  • Control of progress bar label?

    Control of progress bar label?

    Hi there

    As far as I can tell there is currently no way to control the format of the label to the progress bar in animations?

    I have this currently...

    import animatplot as amp
    t = (np.arange(speed.shape[0])/12.+1950)
    tt = t.astype(int)
    .
    .
    .
    anim = amp.Animation([im], amp.Timeline(tt))
    anim.controls()
    anim.save_gif('surface-ocean-circulation')
    

    This gives 1950,1951,... but the labels on the progress bar are to 2 decimal places, see attached screenshot.

    Is it possible to have further control over this, for example integer labels or even strings?

    Many thanks

  • incompatibility with pcolormesh `shading=

    incompatibility with pcolormesh `shading="nearest"` option in matplotlib-3.3

    Adapting the pcolormesh example, and using the new shading="nearest" option from matplotlib-3.3.2

    import numpy as np
    import matplotlib.pyplot as plt
    import animatplot as amp
    
    
    x = np.linspace(-2, 2, 50)
    y = np.linspace(-2, 2, 50)
    t = np.linspace(0, 2*np.pi, 40)
    
    X, Y, T = np.meshgrid(x, y, t)
    
    Z = np.sin(X*X+Y*Y-T)
    
    shading = "nearest"
    #shading = "flat"
    block = amp.blocks.Pcolormesh(X[:,:,0], Y[:,:,0], Z, t_axis=2, cmap='RdBu', shading=shading)
    plt.colorbar(block.quad)
    plt.gca().set_aspect('equal')
    
    anim = amp.Animation([block], amp.Timeline(t))
    
    anim.controls()
    
    anim.save_gif('pcolormesh')
    plt.show()
    

    gives pcolormesh

    instead of the expected result, which we get with shading="flat" pcolormesh

    I suspect this is related to flattening the array here https://github.com/t-makaro/animatplot/blob/632d988687fca7e7415e9fa49fe7eebc3f0991c6/animatplot/blocks/image_like.py#L57-L60

    probably a bug in matplotlib 3.5.2

    Running your example of vect_plot (0.4.2, matplotlib 3.5.2) I get:

    "name": "ValueError",
    	"message": "Passing parameters norm and vmin/vmax simultaneously is not supported.

    can be solved by replacing:

        'vmax': 1000,
        'vmin': .1,
        'cmap': 'pink',
    }
    

    with:

    Adds a new Block subclass Surface to make surface plots using matplotlib's plot_surface() method.

    Makes animation by clearing plot and re-drawing. It was suggested that this is the best solution as majority of time is drawing rather than updating the array anyway, see https://stackoverflow.com/a/45713451/13577592.

    ~Making the vertical axis scale fixed doesn't work at the moment. Seems to be a bug with matplotlib's vmin and vmax arguments, see https://github.com/matplotlib/matplotlib/issues/19870.~

  • tight_layout() compatibility

    tight_layout() compatibility

    This PR attempts to make the animation controls (time-slider and play/pause button) compatible with use of tight_layout().

    Previously, calling tight_layout could arrange the animations in a figure, but would not move or take into account the controls, which would end up overlapping the lower part of the animations.

    This PR seems to work, but requires accessing a private variable of matplotlib.figure.Figure to get the gridspec, in order to modify it to add the controls. Also modifies a private member of matplotlib.gridspec.Gridspec to modify the number of rows. It would be nice if matplotlib provided public methods to access and update gridspecs, but as far as I can see they do not at the moment.

    One issue is that the current implementation seems to reserve too much whitespace around the controls. It would be nice to find a way to allow tight_layout() to modify the amount of space above/below the slider.

  • Would you like more developers?

    Would you like more developers?

    This library is great, you've done a really nice job with it so far @t-makaro .

    I'm using it pretty regularly, and getting close to having it integrated within xarray through https://github.com/pydata/xarray/pull/2729.

    This will hopefully increase the number of people using animatplot (both directly and indirectly through xarray), and will probably mean you get more suggestions and bugs found.

    Would you like any help with the maintainance of the library? Me and @dcherian are both keen to use this, and if one of us also had commit access then we could push bug fixes for you. We could have some kind of "all PRs need a review" rule, and you retain control over the scope? What do you think?

Releases(0.4.1)
  • 0.4.0(Feb 23, 2019)

    The changelog needs to be updated for release.

    • Improved Line Block input handling and testing
    • Added title block
    • Timeline_slider now defaults the format specifier valfmt to None. If set to None, it will use %1.2% for most cases, but %s for np.datetime.

    Backwards incompatible changes:

    • The x, y inputs to the Line Block are not positional only
    • Removed axis kwargs that deprecated in favor of ax in 0.3.0

    Dev changes:

    • testing tools was moving into the tests folder and is no longer a subpackage of animatplot.
    • CircleCI script was refactored

    This release has multiple contributors (and the first release to have such): t-makaro TomNicholas* dcherian*

    *indicates new contributor.

  • 0.3.0(Oct 29, 2018)

    Deprecations

    • The axis keyword argument has been replaced (everywhere) in favour of ax, and axis will be removed completely in 0.4.0. This does not apply to t_axis which is unchanged. See #10 for rational.

    Features

    • The Pcolormesh block now accepts 1D arrays (in addition to 2D) for x and y inputs. Animation.timeline_slider now accepts a text argument to change the name of the slider.
    • New blocks:
      • Scatter for animating scatter plots. Capable of animating size and position of the points, but not yet the color.
      • Update a block that accepts a generic function that takes a frame number. Good if another block doesn’t already exist for some tasks.
    • Composition Blocks: These are functions that return a list of blocks (and maybe a timeline). These are in the blocks subpackage and can be identified by the _comp suffix.
    • New (and very experimental) animations subpackage (well new to the public api). Contains some new convenice functions.
      • vector_plot wraps Pcolormesh and Quiver to produce animated vector fields.

    Bug Fixes

    • Previously, an Animation with a timeline_slider, but no toggle would cause an error.

    Breaking Changes

    • The text argument to timeline_slider is now the first positional argument.
    • The order of positional arguments for the Nuke block has changed. This was required to give the ax argument a default.

    Developer Changes

    • New animation unittesting framework
    • Tests / doc building now runs on CircleCI.
