当我将Plotly Interactive Graph悬停在折线图中的特定点上时，如何更改显示的内容

Question

The title explains it all. Currently it just displays the X and Y values of that specific point but I would like it to display some text that is associated with that point. Is there a way to manually override what is displayed in these interactive plots?

fig = plt.figure(figsize=(15,7))
plt.plot(X1,Y1, label = 'One')
plt.plot(X2,Y2, label = 'Two')
plt.ylim([-1.0,1.0])
leg = plt.legend(loc='lower right',
       ncol=3,
       fontsize=15,
        fancybox=True)
leg.get_frame().set_facecolor('white')
leg.get_frame().set_edgecolor('grey')
plt.show()

py.iplot_mpl(fig)

I'm just converting a simple Matplotlib code to a plotly plot. Any advice will be much appreciated.

Just add the text attribute to your trace to control the text which is shown when you hover over the data point.

import plotly.plotly as py
import plotly.graph_objs as go

trace0 = go.Scatter(
    x=[1, 2, 3],
    y=[1, 2, 3],
    text=['One', 'Two', 'Three'],
    mode='markers'
)

data = go.Data([trace0])
plot_url = py.plot(data)
