Arrays of rasterized values build by datashader can be visualized using plotly's heatmaps, as shown in the plotly and datashader tutorial. See function reference for px.(imshow) or https://plotly.com/python/reference/heatmap/ for more information and chart attribute options!

If "x" (the default value), the x coordinates refer to `layout.xaxis`. If "x2", the x coordinates refer to `layout.xaxis2`, and so on. yaxis Code: fig.update_traces(yaxis=<VALUE>, selector=dict(type='heatmap')) Type: subplotid Default: y

If “scaled”, the heatmap’s x coordinates are given by “x0” and “dx” (the default behavior when x is not provided). ... y0 – Alternate to y. Builds a linear space of y coordinates. Use with dy where y0 is the starting coordinate and dy the step. yaxis – Sets a reference between this trace’s y coordinates and a 2D cartesian y axis.

yref Parent: data[type=heatmap].colorbar Type: enumerated , one of ( "container" | "paper" ) Default: "paper" Sets the container `y` refers to. "container" spans the entire `height` of the plot.

import plotly.express as px import numpy as np np.random.seed(1) z = np.random.randn(20, 20) fig = px.imshow(z, text_auto=".2f", color_continuous_scale='Greys', aspect="auto") fig.show() px.imshow() can produce more elaborate annotated heatmaps. The example below renders a periodic table: the cell labels come from a custom text array, while customdata combined with a hovertemplate displays the element name and atomic mass on hover.

The following example uses this prompt structure with the delivery_location and factory_location columns from the built-in Plotly Studio dataset, with a count aggregation: Products by Factory and Delivery Location Chart: - Type: heatmap - X: Delivery location - Y: Factory location - Values: Count of products Data: - Aggregation: count by Factory location and Delivery location

August 17, 2023 - Plotly Express is a high-level interface for Plotly that makes it easier to create complex visualizations with less code. It's particularly useful for creating heatmaps. Here's an example of how to create a heatmap with Plotly Express:
