Summary of sizing graphs with Dash: In summary: - Setting the size of the container is done with `dcc.Graph(style={...})`. These are CSS styles, so any units work: `%`, `px`, `vh`, `vw`. The Graph should expand into the container. - The `figure` of the graph can also have dimensions and these are specified through the `layout`, `figure={'layout': {'width': '100px'}}`. Only `px` are supported here. I don’t think that there are any advantages to setting the dimensions in the figure rather than the container (as in `style=` as above). - When the window resize, the graph is automatically re-plotted _inside_ the container - expanding to the container’s dimensions. Behind-the-scenes, this is happening with the `Plotly.resize` plotly.js call (here’s the code: [https://github.com/plotly/dash-core-components/blob/c898d75a1a189943bcf92bc73b95bd08432ddd7d/src/components/Graph.react.js#L127-L129](https://github.com/plotly/dash-core-components/blob/c898d75a1a189943bcf92bc73b95bd08432ddd7d/src/components/Graph.react.js#L127-L129)) - Note that if the container itself is resizable, the graph will not be replotted/resized. There isn’t a reliable way to tell if a graph’s container has changed size in JavaScript yet, so we’re just checking if the window is resized. --- _[View the full topic](https://community.plotly.com/t/cant-seem-to-change-default-height-on-graph/6742)._
