Update hover-text-and-formatting.md

[staceybeck]

The chart was not plotting the correct country name with the data point in the hover. Just needed to pass in the 'continent' column data from the continent_data dictionary.

Doc upgrade checklist:

• random seed is set if using random data
• file has been moved from unconverted/x/y.md to x/y.md
• old boilerplate at top and bottom of file has been removed
• Every example is independently runnable and is optimized for short line count
• no more plot() or iplot()
• graph_objs has been renamed to graph_objects
• fig = <something> call is high up in each example
• minimal creation of intermediate trace objects
• liberal use of add_trace and update_layout
• fig.show() at the end of each example
• px example at the top if appropriate
• minimize usage of hex codes for colors in favour of those in https://github.com/plotly/plotly.py-docs/issues/14

Thank you @yecatstevir ! In fact I just noticed there are several issues with this example: in the hovertemplate x and y are inverted, and the population is the square root of the right value. I believe this part of the code should be

for continent_name, continent in continent_data.items():
    fig.add_trace(go.Scatter(
        x=continent['gdpPercap'],
        y=continent['lifeExp'],
        name=continent_name,
        text=continent['country'],
        customdata=continent['pop'],
        hovertemplate=
        "<b>%{text}</b><br><br>" +
        "GDP per Capita: %{x:$,.0f}<br>" +
        "Life Expectation: %{y:.0f}<br>" +
        "Population: %{customdata:,}" +
        "<extra></extra>",
        marker_size=continent['size'],
        ))

Does this sound correct to you? Thanks for noticing the problem :-)

Wow that is awesome! Im glad we were able to figure this out. I am very new to github so I am glad you got back to me. :) Plotly has been fun so far as I just started a master's degree in data science at University of Michigan and we are learning about different visualizations.

Happy to know you're having fun with Plotly ;-). Would you like to give it a try and make the other changes to this example?

[staceybeck]

Ah yes, sorry about that, I will go back to take a look.

@emmanuelle if you have a chance, could you please move this over to the plotly.py repo, with the other fixes you found?
