Hi! Could you please provide an example? This will help us a lot.
Sure. Here is an example of some code I've been trying to run:
plot = (
ggplot(core_10004_1A_1, aes("value", "depth_m", group="section_no")) +
ggsize(150, 500) +
geom_line() +
facet_grid(x="channel", scales="free") +
scale_y_reverse() +
labs(x="Values", y="Depth (m)") +
theme(legend_position="none")
)
ggsave(plot, "plot_test.png")
I've tried to get the resulting plot to show in Jupyter as well as save it locally in case this is a Jupyter issue. I get the same outcome in either case.
This is what I get when I use geom_line:
However, when I use geom_path, I get the error message I previously mentioned.
Running the same code using geom_path (and some minor tweaks due to library differences) using plotnine gives me closer to what I'm looking for:
Thanks! The code is totally fine. Could you please attach your data (core_10004_1A_1
) if possible? Looks like it is the key for fixing the issue.
Sure. Here it is. FYI, it's tab-delimited and has about 200,000 records. The original has close to 500,000, but it's too large for me to upload here. Hopefully, this should be good enough.
Thank you! I'v reproduced the issue.
To workaround the problem add sampling='none'
to geom_path(...)
.
Full code:
plot = (
ggplot(core_10004_1A_1, aes("value", "depth_m", group="section_no")) +
ggsize(150, 500) +
geom_path(sampling='none') +
facet_grid(x="channel", scales="free") +
scale_y_reverse() +
labs(x="Values", y="Depth (m)") +
theme(legend_position="none")
)
plot
That works! Thanks!
You referred to this as a workaround. I assume that this is not intended behavior? Will this be addressed in a future version?
Thank you again!

Definitely.
I've been trying out lets-plot through a Jupyter notebook on Windows 11.
I'm experiencing an issue that comes up when I use geom_path. I receive this error message both when trying to view a plot in Jupyter and when trying to save the image using ggsave, regardless of file format:
Exception: Internal error: NullPointerException : <no message>
Unfortunately, that's all I receive. Using geom_line in place of geom_path produces a graph, but not always with the desired result.
