By default showlegend Parameter is true. When we draw a plot in plotly legend is always displayed.
In the below code we introduce a new parameter, legend_traceorder, and initialize is to “reversed”, the order of the legend is reversed by doing so.
Python3
After changing order:
The order setosa, versicolor , verginica is changed to virginica, versicolour , setosa.
Example 3: Changing orientation of the legend
For a horizontal legend, set the layout.legend.orientation attribute to “h.” We also put it over the plotting area here. Generally, the legend is displayed vertically.
Python3
Example 4: Changing size, font, and color of legend
In this example, many other parameters are introduced, such as title_font_family, font where a dictionary of sub-parameters are specified for styling, bgcolor which is background colour, border colour and border width.
