How can I show numbers in the plot in millions ?
How are you creating the bar chart? If it in express, then
text_auto=True would use the same units as the y-axis. Otherwise you can provide a format string to it, like `text_auto=.3s" (SI format with 3 significative digits, so 1225110 => 1.22M).
If you are using graph objects, then you can specify the texttemplate for the trace by adding
go.Bar(same format as above), or using
The format follows the d3-format notation, which can be a bit tricky to figure out in special cases (so now you know where this comes from).
