Metric name don't appear completely in plotly view

[cdancette]

A possible fix I did in my local repo is to add the line

                scatter = go.Scatter(
                    x = x,
                    y = y,
                    name = view['view_interim'],
                    line = dict(color=color),
+                   hoverlabel=dict(namelength = -1),
                )
