Tap and legends problem

This relates to panel issue https://github.com/pyviz/panel/issues/135

    typ = param.ObjectSelector(default='curve', objects=['curve','scatter'])
    
    def callback(self, x, y):
        x = 0 if x is None else x
        y = 0 if y is None else y
        el = hv.Curve if self.typ == 'curve' else hv.Scatter
        h = el(((x,0),(y,1)))
        return h.redim.range(x=(-1,1), y=(-1,1)).relabel('{},{}'.format(x,y)).options(show_grid=True)

    @param.depends('typ')
    def view(self):
        return hv.DynamicMap(self.callback, streams=[SingleTap(transient=True)])

selection     = Selection(name="Ouch")
pn.Column( 'Click on the plot or change plot type', selection.param, selection.view)

Clicking on a legend triggers the callback function with values outside the viewable plot region.

I think that is also a bug in any case, so it’ll be fixed too.

Now fixed.
