We can use the align parameter to change the position of the x-ticks. Similar to the example above but: normalize the values by dividing by the total amounts. The example Python code draws a variety of bar charts for various DataFrame instances. For detailed column-input-format documentation, see the Plotly Express Arguments documentation.
