Legends are not shown about px-simple-bar-chart HOT 4 CLOSED

I thought this was an issue because the demo page has 4 demo labels but only 1 series for that example, but changing the number of labels didn't fix it. It may be programmed intentionally to not show the legend when there is only one series, I'm not sure.

That's what I think too. I believe the labels are only for when you are using multi-series.

I checked the code:

        _requireLegend: function() {
            // legend is required if any of the
            return this.chartData.length > 1;
        }

According to this function it seems legends are only available for multi-series.
It will be helpful if documentation includes this information.

It would be great if single series chart has legends too. Without labels or legends this component is not useful.

I've updated the function as follows in v1.9.0:

_requireLegend: function() {
            // legend is required if legend labels are supplied, otherwise omitted
            return this.legendLabels.length > 0;
        },
