Word cloud is not selected in cross flter

[AAA]

Hi I am new to dc.js. I am implementing word cloud with the bar chart using crossfilter. 

My problem is when I am selecting bar chart it shows respective data in cloud but I am unable to select cloud data so it will show on bar.

Here is my code.

Please help me  .

It looks like the library dc-wordcloud which you are using does not have support for selections built in. You'd have to either modify the library or add a click handler after the chart has rendered. Something like (untested):

wordcloudChart.on(‘pretransition’, function(chart) {

    chart.selectAll(‘text’).on(‘click’, function(d) {

        wordDim.filter(d.text);

        dc.redrawAll();

    });

});

Thanks Gordon it really works :) But the only problem is the words having count 1 (means exists once) are not displaying. Where I have to define the size? Your help is highly appreciated

Awesome!

Looking at the source for this dc-wordcloud (which I hadn't seen before, thanks for pointing it out), there is this function:

function checkSize(d){

            var x = 0;

            if(d.value <= 0) { 

                x = 0

            } else { 

                x = Math.log(d.value)*_chart.relativeSize();

            }

            return x;

}

which makes sense, to log-scale the sizes. 

But log(1) == 0 so I think you'll need to change the code. And please, when you do, submit a PR or issue with the author and say thanks!
