Stack Multiple Cross-layouts

StackBoard offers an alternative way to place multiple cross-layouts. Unlike CompositeBoard, it can also stack itself.

Warning

The StackBoard is still considered experimental. There might be some issues with the rendering.

Let’s create three different heatmaps for demonstration:

>>> import marsilea as ma
>>> import marsilea.plotter as mp
>>> import numpy as np
>>> data1 = np.random.rand(10, 15)
>>> data2 = np.random.rand(20, 10)
>>> data3 = np.random.rand(15, 20)
>>> h1 = ma.Heatmap(data1, cmap="Reds", height=1, width=1.5)
>>> h1.add_top(mp.Colors(data1.sum(axis=0)), size=0.2, pad=0.1)
>>> h2 = ma.Heatmap(data2, cmap="Greens", height=2, width=1)
>>> h2.add_right(mp.Colors(data2.sum(axis=1)), size=0.3, pad=0.1)
>>> h2.add_left(mp.Colors(data2.sum(axis=1)), size=0.3, pad=0.1)
>>> h3 = ma.Heatmap(data3, cmap="Blues", height=1.5, width=2)
>>> h3.add_bottom(mp.Colors(data3.sum(axis=0)), size=0.1, pad=0.1)

We can stack them in different ways, notice that the alignment is relative to the main canvas:

direction="horizontal" and align="top":

>>> sb = ma.StackBoard([h1, h2, h3], direction="horizontal", align="top")
>>> sb.render()

direction="horizontal" and align="center":

>>> sb = ma.StackBoard([h1, h2, h3], direction="horizontal", align="center")
>>> sb.render()

direction="horizontal" and align="bottom":

>>> sb = ma.StackBoard([h1, h2, h3], direction="horizontal", align="bottom")
>>> sb.render()

direction="vertical" and align="left":

>>> sb = ma.StackBoard([h1, h2, h3], direction="vertical", align="left")
>>> sb.render()

direction="vertical" and align="center":

>>> sb = ma.StackBoard([h1, h2, h3], direction="vertical", align="center")
>>> sb.render()

direction="vertical" and align="right":

>>> sb = ma.StackBoard([h1, h2, h3], direction="vertical", align="right")
>>> sb.render()

Grid of heatmaps?

You can also stack multiple heatmaps in a grid layout. For example, let’s stack

>>> data = np.random.rand(10, 10)
>>> h1 = ma.Heatmap(data, cmap="Reds", height=1, width=1)
>>> h2 = ma.Heatmap(data, cmap="Greens", height=1, width=1)
>>> h3 = ma.Heatmap(data, cmap="Blues", height=1, width=1)
>>> h4 = ma.Heatmap(data, cmap="Purples", height=1, width=1)
>>> sb1 = ma.StackBoard([h1, h2], direction="horizontal", align="center")
>>> sb2 = ma.StackBoard([h3, h4], direction="horizontal", align="center")
>>> final_sb = ma.StackBoard([sb1, sb2], direction="vertical", align="center")
>>> final_sb.render()
