How to set the colored boxes in a specific order in plotly box plot?-CodePudding

I currently have a boxplot in plotly like so:

Below is the Code I used to generate it:

data = Audit_grouped[(Audit_grouped['type'] == t)
                      & (Audit_grouped['rank_desc'] == i)]
              

fig = px.box(data, x = "year", y = "hours", color = "results",
             color_discrete_map = {'Pass': 'green', 'Fail': 'red'},
             labels={"hours":"hours(sum)"}
             )

fig.update_layout(xaxis={'categoryorder':'category ascending'})
fig.update_traces(quartilemethod="linear")
fig.show()
fig.write_image('Audit '  str(i)   ' ('   str(t)   ').png')

I want to have the Fail boxplot be displayed on the left side first as opposed to it being on the right side.

How would I go on to do that?

CodePudding user response：

you can define that with the parameter category_orders when you create the box plot instead of updating the axes

in your case this will be as follow:

fig = px.box(data, x = "year", y = "hours", color = "results",
             color_discrete_map = {'Pass': 'green', 'Fail': 'red'},
             labels={"hours":"hours(sum)"},
             category_orders={"results": ["Fail", "Pass"]}) # this is new line
