I have a python cell in my Quarto notebook like:

```auto
#| echo: false

print(type(run_fastqc))
if run_fastqc:
    print(run_fastqc)
    fastqc_seqgc_plot = multiqc.get_plot("fastqc", "Per Sequence GC Content")
    fastqc_seqgc_plot.show()

```

However the plot is not showing up. The panel only shows:

```auto
<class 'bool'>
True

```

If I move the plot to outside the `if` statement

```auto
#| echo: false

print(type(run_fastqc))
if run_fastqc:
    print(run_fastqc)

fastqc_seqgc_plot = multiqc.get_plot("fastqc", "Per Sequence GC Content")
fastqc_seqgc_plot.show()

```

The plot shows up. Am I doing something silly (I have little understanding of python) or is this a bug?

Repo with reproducible example:[GitHub - mahesh-panchal/nextflow-quarto-multiqc-demo: Using Quarto within Nextflow to make a MultiQC report](https://github.com/mahesh-panchal/nextflow-quarto-multiqc-demo/tree/main)

Open in Gitpod and use

```auto
pixi run nextflow

```

The last process makes the quarto notebook. The qmd is located in `docs/multiqc_report`. The html is written to results/report.

It seems using a ternary conditional is the solution here ( even with MultiQC 1.25 )

```auto
#| echo: false

# Have to use the ternary style syntax for if to make the plot show
# This doesn't work!
# if run_fastqc:
# multiqc.get_plot("fastqc", "Sequence Counts").show()
# This does!
multiqc.get_plot("fastqc", "Sequence Counts").show() if run_fastqc else ""

```

Thanks again to bring this up and sorry for not getting back to your question sooner.  
As we discussed in person, you are correct that `display` is needed to be called on `show` output unless it’s the last line in a cell. Jupyter automatically displays the output of the last line it called, but if it’s within a conditional, the output will be discarded.

Clarified that in the docs with [Document use of display to show plots in notebooks by vladsavelyev · Pull Request #2938 · MultiQC/MultiQC · GitHub](https://github.com/MultiQC/MultiQC/pull/2938)
