  • fix: proper p9 version check, support for >0.10

    fix: proper p9 version check, support for >0.10

    As stated in #25, patchworklib doesn't currently support the current plotnine release.

    The issue in place arises from the way plotnine's version is checked, since my understanding is that patchworklib supports plotnine releases starting from 0.8. The next major release (0.9) made some breaking changes which patchworklib handles by doing a simple string check to ensure whether the version is 0.8 or 0.9 so as to handle the ggplot drawing. This has, however, two unintended consequences:

    (1) Any plotnine release newer than 0.9 breaks patchworklib. (2) Any plotnine release with substrings containing 0.9 or 0.8 (such as a possible 0.10.8, for instance) will match the incorrect version and will be handled in the wrong manner.

    The fix is pretty trivial, and depends on the parse_version function of pkg_resources, which is in itself a dependency of setuptools that is already a dependency of patchworklib, so we aren't adding any extra dependencies.

    Comparisons are now made through the properly parsed versions, and any newer versions of plotnine should be handled appropiately now.

    By the way, thanks for the very useful library!

  • Iteratively generate plots and combine

    Iteratively generate plots and combine

    Hello!

    I am currently working on some code whereby I iteratively generate a list of plots using plotnine and I want to also be able to combine them all into one figure. Depending on when I run this code there may be a variable number of plots, and so I can not use the basic syntax of patchworklib.

    So my question is if there is a way with patchworklib to combine a list of plots together, instead of having to specify individual plot objects (ie "plot1 | plot2"). There doesn't seem to be a lot of options to do this using plotnine, but prefer it over the murky waters of matplotlib.

    Thanks for any help! Kurt

  • Problem with theme_gray in plotnine (Can't support Plotnine 0.9.0)

    Problem with theme_gray in plotnine (Can't support Plotnine 0.9.0)

    Dear ponnhide,

    I would like firstly to thank you very much for creating and maintaining the patchworklib.

    In addition, I would like to comment about an issue I am getting when using it to arrange plotnine graphics. As an example, I will use the same one you have previously shared in: https://pypi.org/project/patchworklib/

    -- Code -- import patchworklib as pw from plotnine import * from plotnine.data import * g1 = pw.load_ggplot(ggplot(mtcars) + geom_point(aes("mpg", "disp")) + theme(figure_size=(2, 3))) g2 = pw.load_ggplot(ggplot(mtcars) + geom_boxplot(aes("gear", "disp", group = "gear")) + theme(figure_size=(2, 3))) g12 = g1 | g2 g12.savefig()

    -- Output --

    AttributeError Traceback (most recent call last) in <cell line: 4>() [2]from plotnine import * [3]from plotnine.data import * ----> [4]g1 = pw.load_ggplot(ggplot(mtcars) + geom_point(aes("mpg", "disp")) + theme(figure_size=(2, 3))) [5]g2 = pw.load_ggplot(ggplot(mtcars) + geom_boxplot(aes("gear", "disp", group = "gear")) + theme(figure_size=(2, 3))) [6]g12 = g1 | g2

    File C:\Users\rodrife\Anaconda3\lib\site-packages\patchworklib\patchworklib.py:401, in load_ggplot(ggplot, figsize) [399]ggplot._draw_breaks_and_labels() [400]ggplot._draw_watermarks() --> [401]ggplot._apply_theme() [403]if len(ggplot.axs) == 1: [404]ax = Brick(ax=ggplot.axs[0])

    AttributeError: 'theme_gray' object has no attribute 'apply_axs'

    I see it might be trying to apply theme attributes to Matplotlib objects, although in this case there is a plotnine object. However, since this is your example, it may be that I could have something wrong in my environment (e.g. plotnine or patchworklib). In any case, I would really appreciate any helping comment from your side.

    Thank you very much in advance! With my very best regards, Fermin

  • How to turn off/modify legend in Patchworklib

    How to turn off/modify legend in Patchworklib

    Hello, thank you for your amazing tool so that I can make better pictures for my graduation thesis. I'm now having trouble on turning off/modifying the size of the legend in the combined pictures. I'm not a professional programmer so I'm not sure if it's my problem or if this function is not included in this package. I'll paste my code below:

    p1 = (
            ggplot(flight_01, aes(x='t_plot', y='FL1', shape="legend", color="legend"))
            + geom_point(alpha=0.5, size=0.5)
            + scale_x_datetime(labels=date_format('%H:%M'))
            + scale_color_manual(values=['tomato'], breaks=['trajectory'])
            + xlab("time [h]")
            + ylab("altitude x 10^2 [ft]")
            + ggtitle("Flight trajectory "+str(num[0])+"")
            + theme_gray()
            + theme(
                    legend_title=element_blank(),
                    figure_size=(12, 9),
                    legend_position='none',
                    legend_box='horizontal',
            )
    )
    
    p2 = (
            ggplot(flight_02, aes(x='t_plot', y='FL1', shape="legend", color="legend"))
            + geom_point(alpha=0.5, size=0.5)
            + scale_x_datetime(labels=date_format('%H:%M'))
            + scale_color_manual(values=['tomato'], breaks=['trajectory'])
            # + scale_x_datetime(breaks="30 minute", labels=date_format('%H:%M'))
            + xlab("time [h]")
            + ylab("altitude x 10^2 [ft]")
            + ggtitle("Flight trajectory "+str(num[1])+"")
            + theme_gray()
            + theme(
                    legend_title=element_blank(),
                    figure_size=(12, 9),
                    legend_position='right',
                    legend_box='horizontal',
                    legend_text=element_text(size=5)
            )
    )
    print(p1)
    print(p2)
    
    p1 = pw.load_ggplot(p1, figsize=(4, 3))
    p2 = pw.load_ggplot(p2, figsize=(4, 3))
    g1234 = p1|p2
    g1234.savefig("G:/DA/combi.png")
    

    As you can see I turn the legend off for p1 and keep only p2. I also turn off the word "legend" for p2 and make the text size smaller so that the width of the combined pic can be thinner.

    But in the combined pic g1234, the word "legend" is still there and the size of the legend remains the same as the title, which I didn't change at all. And the pics made by "print" are working as I wanted.

    Could you give me some advice on this? Thx a lot!

  • Handle seaborn plots generated based on figure-level function in patchworklib

    Handle seaborn plots generated based on figure-level function in patchworklib

    Seaborn plots generated based on figure-level function cannot be handled as matplotlib subplots. The issue is mentioned in some places (https://github.com/mwaskom/seaborn/issues/2666, https://github.com/mwaskom/seaborn/issues/2059). Now, patchworklib can import the following plots as Bricks class objects and align them with other plots.

    • [x] pairplot
    • [x] relplot
    • [x] jointplot
    • [x] catplot
    • [x] displot

    However, it still cannot handle clustermap plots based on clustermap function.

  • Plotnine legend position is reset after using patchworklib

    Plotnine legend position is reset after using patchworklib

    I've noticed that my original ggplot legend position is not maintained after patching together. I used...

    • theme(legend_position=(.5, -0.02), legend_direction='horizontal')

    ...to position it underneath each individual ggplot before combining with patchworklib. However, after patching together, the legend goes back to the right side for every sub-plot.

    Is this related to the same issue as in #15? Thanks.

    The size of the subgraph will automatically change

    patchworklib has saved me a lot of effort consumed in the layout.

    But recently I found that in some special cases it automatically modifies the size of the subgraph.

    ls_ax = []
    for i in range(10):
        ls_ax.append(pw.Brick(f"ax{i}", (3, 3)))
    ls_ax = [ls_ax[:3], ls_ax[3:6], ls_ax[6:9], ls_ax[9]]
    _axs = [reduce(lambda x,y: x|y, z) for z in ls_ax[:-1]]
    _axs = reduce(lambda x,y: x/y, _axs)
    _axs = _axs['ax6'] / ls_ax[-1]
    
    _axs.savefig()

  • Replace final plotnine version check.

    Replace final plotnine version check.

    Based on the work of @AlFontal's commit #26 in response to issue #25, replace the final plotnine version check as it still failed when using plotnine's facet_grid and facet_wrap.

    The failure can be seen in the 'subplots for plotnine' Colab linked from the ReadMe.

    Colab Result: image

    The failure can also be reproduced with the example below:

    import pandas as pd
    import patchworklib as pw
    import plotnine as p9
    
    df = pd.DataFrame({'a': range(10), 'b': ['x', 'y']*5})
    
    work_around = False
    if work_around:
    	df1 = df.query('b == "x"')
    	g1 = (p9.ggplot(df1, p9.aes(x=df1.index, y='a')) 
    		+ p9.geom_line()
    		)
    	df2 = df.query('b == "y"')
    	g2 = (p9.ggplot(df2, p9.aes(x=df2.index, y='a')) 
    		+ p9.geom_line()
    		)
    	
    	success1 = pw.load_ggplot(g1)
    	success2 = pw.load_ggplot(g2)
    
    	g = success1|success2
    	g.savefig('success')
    else:
    	g = (p9.ggplot(df, p9.aes(x=df.index, y='a', colour='factor(b)')) 
    		+ p9.geom_line()
    		+ p9.facet_wrap('~b')
    		)
    	failure = pw.load_ggplot(g)
    	# Produces error: Type Error: argument of type 'Version' is not iterable
    	print(g)
    

    From my testing it now works with facet_grid and facet_wrap.

    Please excuse any incompetence as I am a novice.

    I'm not quite sure how to test everything, but some tests that run the patchwork examples would probably go a good distance in catching different errors that arise. The cowpatch tests might be of some inspiration.

    You can configure github actions to run the tests on every commit / PR as well as on a scheduled basis to detect for example if a dependency update breaks something. Happy to help set up the actions.

    Have you using GitHub Actions to deploy to PyPI? This way whenever you create a release on GitHub at https://github.com/ponnhide/patchworklib/releases/new, it will automatically be deployed to PyPI. You'll get the git tag automatically. Also you can put release notes on the GitHub Release (rather than in the readme).
