HoverInfo is truncated with long variable names

[AMarthaller]

There doesn't appear to be a way to specify the hoverinfo width. With longer variable names the strings are truncated with ellipses. I haven't tried any of the samples for providing custom hoverinfo text since I'm using the R API and overriding event handlers is not supported (as far as I can tell).

It would be nice if the desired tooltip dimensions could be specified.

Not at the moment.

Here's a workaround: http://codepen.io/etpinard/pen/LNJmeM

I think this is not a solution. I would like the text to be same in legend and in hover tooltip. now in your workaround you have trace1, trace2 in legend which is not so informative.

I have to put the same information into text, and into name of trace to achive this, but then in tooltip information is displayed twice.

@nothinkelse you can set the trace hoverinfo to x+y+text (instead of the default x+y+text+name) to remove the trace name from the hover labels.

This is still not very satisfying. I know it seems minor, but from a stylistic standpoint, it's much nicer to be able to use the separation of styling between the number shown and the label. This is automatic with hovertext=name, but the unfortunately truncation happens. Hovertext=text works to display the full label, however, the styling is less satisfying (causes an extra tall hovertext box, no separation between number and label making it harder for the eyes to quickly parse). Furthermore, as others have pointed out, you may want to display separate information in the text field from the name field and display both without truncation: https://community.plot.ly/t/re-size-hover-info-box/955/2

Since the hovertext boxes can already be really wide to accommodate long text fields, why not just allow name fields to also grow the width of the hovertext box in a similar manner? It could even be a simple flag: truncatename: true/false, with true as default so as not to change current default behavior.

I am currently having the same problem and the workaround is not doing it for me. This is my plot

If I were to change hoverinfo to "text" and change the text to include the name of the trace, then the trace name will appear inside the bar along with the numbers like so.

Is there a workaround for this?

try using using hoverlabel = dict(namelength = -1) instead

example:

line = dict(type='scatter',
                x = x_vector,
                y = y_vector,
                mode = 'lines+markers',
                name = base.columns[i],
                hoverlabel = dict(namelength = -1)
               )

adding hoverlabel: {namelength :-1} into my trace object did the trick.
