hoverinfo: name field not included for HeatMap

Code

run inside of a jupyter notebook cell...

import numpy as np
import plotly  # plotly.__version__ == '2.0.6'
plotly.offline.init_notebook_mode()
import plotly.graph_objs as go

rows, cols = 3, 3 
data = np.random.rand(rows, cols)
py.iplot(go.Figure(
    data=[go.Heatmap(
        name="CUSTOM NAME",  # This SHOULD show up in the hoverinfo?
        x=range(rows + 1), 
        y=range(cols + 1), 
        z=data, 
        text=np.where(data < .5, '<.5', '>.5'),
        hoverinfo="name+text",  # Want to see "CUSTOM NAME"
        colorscale='Greens', reversescale=True, showscale=False
    )], 
    layout=go.Layout(
        title="Test", 
        xaxis=dict(title='X-Axis'),
        yaxis=dict(title='Y-Axis'),
    )
))

Result

it's a bit small, but you can see that the hovertext lacks the CUSTOM NAME text.

Thanks for report.

You're hoverinfo: 'name' doesn't work currently for heatmap.

@etpinard

@etpinard if you want to include this fix in your hover labels PR, it's as simple as removing:
&& d.zLabelVal === undefined
from https://github.com/plotly/plotly.js/pull/1582/files#diff-53eaf7f3ac3274b40206f89f8f87a5d6R689

I don't really recall why that condition was put in there - maybe on the idea that you're already showing lots of info about heatmap points and you don't want to show more? Probably some long-obsolete rationale. 🔪
