Using a list for x and y axis in plotly

Question

I have a Python list that I want to use to chart a line chart in Plotly. The list contains accidents in each week of the year. So for instance list[5]=12 would indicate that in week 5 of 2020, there were 12 accidents. I want to draw a line chart showing the trend of accidents in 2020.

The full list split into two lists is as follows:

x axis [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53]
y axis [0, 0, 0, 2, 3, 4, 2, 3, 2, 2, 6, 4, 2, 1, 2, 1, 1, 3, 1, 0, 0, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 1, 0, 0, 3, 0, 0, 0, 2, 0, 0, 3, 0, 2, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0]

If I enumerate the single list it is as follows:

for e,i in enumerate(my_list):
    print(f"e->{e}, i->{i}")
    e->0, i->0
    e->1, i->0
    e->2, i->0
    e->3, i->2
    e->4, i->3
    e->5, i->4
    e->6, i->2
    e->7, i->3
    e->8, i->2
    e->9, i->2
    e->10, i->6
    e->11, i->4
    e->12, i->2
    e->13, i->1
    e->14, i->2
    e->15, i->1
    e->16, i->1
    e->17, i->3
    e->18, i->1
    e->19, i->0
    e->20, i->0
    e->21, i->0
    e->22, i->0
    e->23, i->0
    e->24, i->0
    e->25, i->0
    e->26, i->0
    e->27, i->0
    e->28, i->0
    e->29, i->0
    e->30, i->0
    e->31, i->0
    e->32, i->0
    e->33, i->0
    e->34, i->0
    e->35, i->0
    e->36, i->0
    e->37, i->0
    e->38, i->0
    e->39, i->0
    e->40, i->0
    e->41, i->0
    e->42, i->0
    e->43, i->0
    e->44, i->0
    e->45, i->0
    e->46, i->0
    e->47, i->0
    e->48, i->0
    e->49, i->0
    e->50, i->0
    e->51, i->0
    e->52, i->0
    e->53, i->0

The index of the list will be X axis and the value will be the Y axis. Normally what I do is use two lists as follows:

# load the x and y axis
my_figure = px.line(x=x_list, y=y_list, title="Testing")
                       

# now draw the line chart
dcc.Graph(id='my_figure', figure=my_figure),

However, in this case I only have one list, and I want to avoid copying the index value into a 2nd list. How can I use the single list with Plotly to draw a line chart?

Answer 1

You can create a dataframe and then try plotting with that dataframe

df = pd.DataFrame({'x_data':x_list, 'y_data':y_list})

px.line(df, x='x_data', y='y_data', title="Testing")

px.line(df, y='y_data', title="Testing") also works in this case
