orca() does not support file paths

[emallickhossain]

I'm trying to export a static image in R using orca(), but it ignores the file path and just exports it to the current location of the script that I'm running.

For example, if I run orca(image, "/images/plot1.png") from a script located in /code/script.R, it saves it to /code/plot1.png instead of where I specified.

I think this has to do with the R wrapper.

Probably best to post on https://github.com/ropensci/plotly/issues/new

I'm having the same issue on Python 2.7. The filename is correct, but the figure is saved to the current directory instead of in the specified directory.

Can you share a code snippet of your attempt?

Here it is: I am saving two figures to disk, a 2D figure from matplotlib and a 3D figure from Plotly (using Orca). The 2D figure gets successfully saved to ./results/2d/test.png, while my Plotly figure gets saved to ./test.png instead of ./results/3d/test.png

save_dir = 'results'
save_fname = 'test'

if save_dir:

        plt.savefig('{}/2d/{}.png'.format(save_dir, save_fname))
        plt.close()

        call(['orca', 'graph', json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder),
              '-o', '{}/3d/{}.png'.format(save_dir, save_fname)])

[etpinard]

what about:

call(['orca', 'graph', json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder),
              '-d', '{}/3d'.format(save_dir), '-o', '{}.png'.format(save_fname)])

?

[debarundhar]

@etpinard Yup, that works. Thanks!

[etpinard]

Ok great. But yeah

call(['orca', 'graph', json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder),
              '-o', '{}/3d/{}.png'.format(save_dir, save_fname)])

should work too.

Bug confirmed. Thanks for reporting.

The logic here

orca/bin/graph.js

Lines 116 to 117 in be699d6

	const itemName = getItemName(info)
	const outPath = path.resolve(opts.outputDir, `${itemName}.${info.format}`)

doesn't seem quite right.

Hi all.. I'm trying to make some tests with Orca.

I get errors in both Linux and Windows (Windows in a Virtual Machine).

The script used is the same as that one in the Readme.md. From a python3 shell:

from subprocess import call
import json
import plotly

fig = {"data": [{"y": [1,2,1]}]}
call(['orca', 'graph', json.dumps(fig, cls=plotly.utils.PlotlyJSONEncoder)])

the error is:

The following are not valid: graph {"data": [{"y": [1, 2, 1]}]}

With Windows I have to change the call to orca with the option shell=True, but then I get an exit code = 1 (meaning nothing has been done right?).

Plotly version installed in both system is 2.5.1

Thanks for any hint!

@ghtmtt

what does

output in your command prompt?

[ghtmtt]

I think the normal help (in Linux).
