Colorscales in JavaScript

How to set colorscales and heatmap colorscales in D3.js-based JavaScript charts in Plotly.js. Divergent, sequential, and qualitative colorscales.


Building AI apps or dashboards with Plotly.js? Chart Studio enables 1-click export, editing and sharing of Plotly.js charts. If building a full-stack app with Plotly.js, you might save time by building with Dash instead. Schedule a Dash Enterprise demo.
