Plotly Heatmap Edge Color Change

Hello Everyone,

In plotly, how can I set each cell color to white? I looks at the official documents but cannot find any variable relate to that setting.

HI @Jiananz ,

Try this code :

# 
import plotly.graph_objects as go

fig = go.Figure(
    data=[
        go.Heatmap(
            z=[[1, 1, 1], [1, 1, 1], [1, 1, 1]],
            xgap=4,
            ygap=4,
            colorscale=["#08a", "#08a"],
            showscale=False,
        ),
    ],)
fig.update_layout(
    yaxis_scaleanchor="x",
    plot_bgcolor="#fff",
    width=400,
    height=400,
    margin=dict(b=0, t=20, l=0, r=20)
)
fig.show()

The code above is modification of this post below:
