Hi, during the lecture on plotting, [Plotting | JuliaAcademy](https://juliaacademy.com/courses/375479/lectures/5863640) (ca. 3 minutes in), she switches over to the plotlyjs() backend.
When I try that, I get only a blank area instead of a plot.
This is whether I use the “pirates” example, or the “x^2” example, as in:
```nohighlight
using Plots
x = -10:10
y = x.^2
plotlyjs()
plot(x,y, label="line")
scatter!(x,y, label="scatter")
```
If I do the gr() backend it works fine, but with plotlyjs() it’s just a big blank space.
Earlier I was getting an error message about the WebIO extension not being installed, but I exited jupyter lab, went to my shell, ran `python3 -m pip install --upgrade webio_jupyter_extension`, restarted jupyter lab, re-ran the notebook, and then the error went away, and now I just see a big blank space.
How to fix this?
Btw, as per [the troubleshooting instructions](https://juliagizmos.github.io/WebIO.jl/latest/providers/ijulia/), here’s the check that the webio extension is installed:
```nohighlight
$ jupyter labextension list
JupyterLab v3.2.7
/home/shawley/envs/fastproaudio/share/jupyter/labextensions
webio-jupyterlab-provider v0.1.0 enabled OK (python, webio_jupyter_extension)
@jupyter-widgets/jupyterlab-manager v3.0.1 enabled OK (python, jupyterlab_widgets)
```
I’m not using any --user pip installations, and I made sure to install the webio extension and run jupyterlab in the same environment:
```julia
python3 -m pip install webio_jupyter_extension
python3 -m jupyterlab
```
…still just a big ol’ blank area for the plot.

**SOLVED.**
The course lecture doesn’t tell you, and the troubleshooting page doesn’t tell you, but the [README](https://github.com/JuliaPlots/PlotlyJS.jl) file for the plotlyjs() _does_ tell you:
You need to run `jupyter labextension install jupyterlab-plotly` from the command line.
After doing that (and restarting jupyter lab, and re-running the code), everything works. 🥳
