Version

5.0.0

Steps to reproduce

legend: {
                type: 'scroll',
                orient: 'vertical',
                formatter: function(name) {
                   name=‘Legenf’ name;
                    return name;
                },
                tooltip: {
                    show: true,
                },
            },
            tooltip: {
                trigger: 'item',
                formatter: '{b}: {c} ({d}%)',
            },

What is expected?

TITLE

The tooltip in the v5.x version of the legend will inherit the outer tooltip configuration

BODY

Version

5.0.0

Steps to reproduce

legend: {
type:'scroll',
orient:'vertical',
formatter: function(name) {
name=‘Legenf’ name;
return name;
},
tooltip: {
show: true,
},
},
tooltip: {
trigger:'item',
formatter:'{b}: {c} ({d}%)',
},

What is expected?

The tooltip in the legend should not inherit the formatter configuration of the outer tooltip

What is actually happening?

This problem will cause the tooltip to display the wrong content during the legend hover event

That's a breaking change.

option = {
    legend: {
        type: 'scroll',
        orient: 'vertical',
        // This is the formatter of legend text,
        // not the formatter of legend tooltip.
        formatter: function(name) {
            return 'Legend ' + name;
        },
        tooltip: {
            show: true,
            // If no formatter declared, inherit the option.tooltip.formatter.
            // That is the same result as in series.
        },
    },
    tooltip: {
        trigger: 'item',
        formatter: '{b}: {c} ({d}%)',
    },
    series: {
        type: 'bar',
        label: {
            formatter: 'label{a}{b}'
        },
        tooltip: {
            // If no formatter declared, inherit the option.tooltip.formatter.
        }
    }
}

@pissang Is it reasonable for this case?

[pissang]

@100pah I think it's not reasonable. Component and series have different params in the formatter. They should not share one formatter config in most of the cases.

We can have default formatted in the legend component. Not using the user-set tooltip formatter.
