how to add a barLabel for composite stack bar charts? #1172

cheanney · 2016-06-27T14:43:29Z

Hi,

I have a composite stack bar chart. I want to show the count for each bar when a legend is mouseover. Now when I mouse over a legend, the bars are highlighted. I also want to add the barLabel for the highlighted layer.
Here is how the chart looks like:

Here is my code:
`

var composite = dc.compositeChart('#timepoint-chart');

```
var scat = dc.barChart(composite)
```
```
     .gap (65)
```

     .group(scatLevelByTimePoint, 'full scat').valueAccessor(function (d) {

```
         return d.value.s_full;
```
```
     })
```

     .stack(scatLevelByTimePoint, 'partial scat', function (d) {

```
         return d.value.s_partial;
```
```
     })
```

        .stack(scatLevelByTimePoint, 'empty scat', function (d) {

```
            return d.value.s_empty;
```
```
        })
```
```
        .title(function(d) {
```

        if (this.layer !== 'N' && this.layer !== 'Y'){

            var type = this.layer.split(" ")[0];

            var name = this.layer.split(" ")[1];

```
            var c;
```
```
            if (name == 'scat'){
```
```
                c = 's_';
```

                return ['full '+name+': ' + d.value['s_full'],'partial '+name+': ' + d.value['s_partial'], 'empty '+name+': ' + d.value['s_empty']].join('\n');

```
            }
```

            else if (name == 'citrate'){

```
                c  = 'c_';
```

                return ['full '+name+': ' + d.value['c_full'],'partial '+name+': '  + d.value['c_partial'],'empty '+name+': ' + d.value['c_empty']].join('\n');

```
            }
```
```
        }
```
```
        else{
```

            if (this.layer == 'Y' || this.layer == 'N')

                return ['Y: ' + d.value['y_pax'],'N: ' + d.value['n_pax']].join('\n');

```
            else
```

                return this.layer + ": "+d.value;

```
        }

    })

        .colors(d3.scale.ordinal().range(["#495090", "#4d5eef", "#8b95ec"]));

        //.colors(d3.scale.ordinal().range(colorbrewer.RdPu[9]))

```
var citrate = dc.barChart(composite)

```
        .gap (65)

This doesn't strike me as a feature request, more a one-off feature you can add with a renderlet, or maybe a tooltip.

Sorry, but the issue tracker is for reporting bugs and making enhancement requests, not for general support questions. Please ask on Stack Overflow with the dc.js tag, or on the user group, and we will be glad to help you there.

I am closing this.

(P.S. It pains me to see people going through these contortions for a grouped bar chart - could you please try PR #1043?)

Thank you!!

Sorry for posting at the wrong place.

Well there are some things that aren't obvious. It's not easy to navigate this library without having to endure 'contortions'.

gordonwoodhull · 2021-05-07T11:19:37Z

It's not easy to navigate this library without having to endure 'contortions'.

Yep that’s true! This library evolved and was not originally designed to do all it does.

If you’re looking for a self-consistent, well-thought-out charting library with many of the same features, I recommend checking out Vega Lite.
