Unexpected output/plot created when using scattergl instead of scatter

[cchrysostomou]

Scattergl appears to not be working the same as scatter function. I have found two issues when using scattergl.

1. When I turn hoverinfo to 'none', rather than not getting hovertips, I instead get two intersecting lines on the plot which follow the crosshairs.
2. I cannot seem to plot multiple yaxes and xaxes when using scattergl, but I can get it to work using just scatter.

Here is code demonstrating the issue

Note this code was taken from the tutorial provided here: https://plot.ly/python/2d-density-plots/

Using scatter function will work as expected: There will be no hover info and all plots will appear

import plotly.offline as py
import plotly.graph_objs as go
import matplotlib
%matplotlib inline
py.init_notebook_mode()

import numpy as np

t = np.linspace(-1,1.2,2000)
x = (t3)+(0.3*np.random.randn(2000))
y = (t6)+(0.3*np.random.randn(2000))

trace1 = go.Scatter(
x=x, y=y, mode='markers', name='points',
marker=dict(color='rgb(102,0,0)', size=2, opacity=0.4),
hoverinfo='none'

)
trace2 = go.Histogram2dcontour(
x=x, y=y, name='density', ncontours=20,
colorscale='Hot', reversescale=True, showscale=False,
hoverinfo='none'

)
trace3 = go.Histogram(
x=x, name='x density',
marker=dict(color='rgb(102,0,0)'),
yaxis='y2'
)
trace4 = go.Histogram(
y=y, name='y density', marker=dict(color='rgb(102,0,0)'),
xaxis='x2'
)
data = [trace1, trace2, trace3, trace4]

layout = go.Layout(
showlegend=False,
autosize=False,
width=600,
height=550,
xaxis=dict(
domain=[0, 0.85],
showgrid=False,
zeroline=False
),
yaxis=dict(
domain=[0, 0.85],
showgrid=False,
zeroline=False
),
margin=dict(
t=50
),
hovermode='closest',
bargap=0,
xaxis2=dict(
domain=[0.85, 1],
showgrid=False,
zeroline=False
),
yaxis2=dict(
domain=[0.85, 1],
showgrid=False,
zeroline=False
),
)

fig = go.Figure(data=data, layout=layout)
py.offline.iplot(fig)

Now if I were to repeat the same code using scattergl, then I will not not be able to see the histograms anymore and there will be two lines following the crosshair

import plotly.offline as py
import plotly.graph_objs as go
import matplotlib
%matplotlib inline
py.init_notebook_mode()

import numpy as np

t = np.linspace(-1,1.2,2000)
x = (t3)+(0.3*np.random.randn(2000))
y = (t6)+(0.3*np.random.randn(2000))

trace1 = go.Scattergl(
x=x, y=y, mode='markers', name='points',
marker=dict(color='rgb(102,0,0)', size=2, opacity=0.4),
hoverinfo='none'

)
trace2 = go.Histogram2dcontour(
x=x, y=y, name='density', ncontours=20,
colorscale='Hot', reversescale=True, showscale=False,
hoverinfo='none'

)
trace3 = go.Histogram(
x=x, name='x density',
marker=dict(color='rgb(102,0,0)'),
yaxis='y2'
)
trace4 = go.Histogram(
y=y, name='y density', marker=dict(color='rgb(102,0,0)'),
xaxis='x2'
)
data = [trace1, trace2, trace3, trace4]

layout = go.Layout(
showlegend=False,
autosize=False,
width=600,
height=550,
xaxis=dict(
domain=[0, 0.85],
showgrid=False,
zeroline=False
),
yaxis=dict(
domain=[0, 0.85],
showgrid=False,
zeroline=False
),
margin=dict(
t=50
),
hovermode='closest',
bargap=0,
xaxis2=dict(
domain=[0.85, 1],
showgrid=False,
zeroline=False
),
yaxis2=dict(
domain=[0.85, 1],
showgrid=False,
zeroline=False
),
)

fig = go.Figure(data=data, layout=layout)
py.offline.iplot(fig)
