plot default type changes for no apparent reason

[alan-krumholz]

I'm Using:
https://github.com/looker-open-source/sdk-examples/blob/master/python/run_look_with_filters.py
To change the filter of a Look before retrieving the png of my visualization.

My Look visualization is an horizontal bar plot
when I do run_look('png')
The png shows the original horizontal bar plot

However when I use the code in:
https://github.com/looker-open-source/sdk-examples/blob/master/python/run_look_with_filters.py
to change the filter for my look the png comes back as a vertical bar plot instead

Is this a bug? can I make it give me back the original horizontal bar plot but with the new filter?

I assume you're creating a new query based of the old look.query but with the new filter? You also have to copy over the old query.vis_config (which that code doesn't do since it's just running the query outputting json). However... you may still run into this issue depending on how complicated your vis_config is.

also, for now you have to do like the example does and copy over attributes from old -> new query but we'll soon launch a feature that does that work for you.

Thanks @joeldodge79! will give that a try.
Looking forward to the simpler feature :) (do let us know when that's out!)

Not sure if related to that issue you linked, but the plots still not look the same even after I copy the vis_config over. Now both are showing horizontal bars (an improvement) but the plot format is all messed up now:

Original:

With new Query:

This is how vis_config looks like in the original look:

{'x_axis_gridlines': 'False',
 'y_axis_gridlines': 'True',
 'show_view_names': 'False',
 'show_y_axis_labels': 'True',
 'show_y_axis_ticks': 'True',
 'y_axis_tick_density': 'default',
 'y_axis_tick_density_custom': '5',
 'show_x_axis_label': 'True',
 'show_x_axis_ticks': 'True',
 'y_axis_scale_mode': 'linear',
 'x_axis_reversed': 'False',
 'y_axis_reversed': 'False',
 'plot_size_by_field': 'False',
 'trellis': '',
 'stacking': '',
 'limit_displayed_rows': 'False',
 'legend_position': 'center',
 'point_style': 'none',
 'show_value_labels': 'False',
 'label_density': '25',
 'x_axis_scale': 'auto',
 'y_axis_combined': 'True',
 'ordering': 'none',
 'show_null_labels': 'False',
 'show_totals_labels': 'False',
 'show_silhouette': 'False',
 'totals_color': '#808080',
 'type': 'looker_bar',
 'defaults_version': '1',
 'series_types': '{}'}

I'll play around with some of those values to see if I can get it to look the same

@joeldodge79 found the problem (I think it is a bug)
when you do look(x).query.vis_config all the boolean values in the dictionary come back as string
e,g, 'True' and 'False' rather than True and False (see comment above with the dictionary printed)

I manually changed all these in the dictionary before copying it over, and that fixed it

    vis = look(x).query.vis_config
    for k in vis.keys():
        if vis[k] == 'True':
            vis[k] = True
        if vis[k] == 'False':
            vis[k] = False

yep, that's the bug. glad that fix worked for you
