How to add up more data in an existing plotly graph?

Question

I have successfully plotted the below data using plotly from an Excel file.

Here is my code:

file_loc1 = "AgeGroupData_time_to_treatment.xlsx"

df_centroid_CoordNew = pd.read_excel(file_loc1, index_col=None, na_values=['NA'], usecols="C:D,AB")
df_centroid_CoordNew.head()

df_centroid_Coord['Ambulance_Treatment_Time'] = df_centroid_Coord ['Base_TT']

fig = px.scatter(df_centroid_Coord, x="x", y="y", 
                 title="Southern Region Centroids", 
                 color='Ambulance_Treatment_Time', 
                 hover_name="KnNamn",
                 hover_data= ['Ambulance_Treatment_Time', "TotPop"],
                 log_x=True, size_max=60, 
                 color_continuous_scale='Reds', range_color=(0.5,2), width=1250, height=1000)

fig.update_traces(marker={'size': 8, 'symbol': 1})
#fig.update_traces(marker={'symbol': 1})
fig.update_layout(paper_bgcolor="LightSteelBlue")

fig.show()

The shapes of the plotted data points are square.

Here is output of my code:

Now, I want to plot more data points in circle or any shapes on the same plotly graph by reading an excel file. Please have a look at the data below.

How I can add up the new data to an existing graph in plotly?

Answer 1

If the data is the same but the column names are different, aligning to either column name is fine for the data for the chart. Add a graph with a graph object by reusing the graph data created with plotly.express. First I added a chart that was already completed, then a chart with latitude and longitude. Station names and locations are drawn using scatterplot markers and text mode.

import plotly.express as px
import plotly.graph_objects as go

df_centroid_Coord['Ambulance_Treatment_Time'] = df_centroid_Coord ['Base_TT']

sca = px.scatter(df_centroid_Coord, x="x", y="y", 
                 title="Southern Region Centroids", 
                 color='Ambulance_Treatment_Time', 
                 #hover_name="KnNamn",
                 #hover_data= ['Ambulance_Treatment_Time', "TotPop"],
                 log_x=True,
                 size_max=60, 
                 color_continuous_scale='Reds',
                 range_color=(0.5,2),
                 )

sca.update_traces(marker={'size': 8, 'symbol': 1})

fig = go.Figure()
fig.add_trace(go.Scatter(sca.data[0]))
fig.add_trace(go.Scatter(x=df_station['x'],
                         y=df_station['y'],
                         mode='markers+text',
                         text=df_station['Ambulance station name'],
                         textposition='top center',
                         marker=dict(
                             size=5,
                             symbol=2,
                             color='blue'
                         )
                        )
             )
              
#fig.update_traces(marker={'symbol': 1})
fig.update_layout(width=625, height=500, paper_bgcolor="LightSteelBlue")

fig.show()
