How can I increase the spacing between two rows in a four-subfigure plot using Quarto custom layout? I'm using Jupyter-lab for coding and Quarto to render pdf. And I have a four-subfigure plot like the one below (modified from the example in https://quarto.org/docs/authoring/figures.html):
#| label: fig-charts
#| fig-cap: Charts
#| fig-subcap:
#| - "First"
#| - "Second"
#| - "Third"
#| - "Fourth"
#| layout-ncol: 2
#| layout: [[45,-10, 45], [45,-10, 45]]
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.show()
plt.plot([1,2,3,4])
plt.show()
plt.plot([1,2,3,4])
plt.show()
plt.plot([1,2,3,4])
plt.show()
I know by adding a negative number (-10) I can increase the horizontal spacing between two subfigures in the same row. But how can I increase the vertical spacing between two rows? I.e. the spacing between the first two and the last two figures? Thanks!
Edit: Problem solved.
See below @shafee's comment! So I shouldn't have put layout-ncol and layout: together.
