Is there a way to turn on

• plotOptions.bar.dataLabels 
• plotOptions.column.dataLabels 
• plotOptions.series.dataLabels 

using the wpDataCharts callbacks feature?  

I know you can turn them on for Export, but I was wanting to turn them on in GUI display.

Yep, I tried that.  It didn't work.  I even cut/pasted your example exactly (except I changed the chart ID) and nothing happens.

I am putting the javascript at the bottom of the page that has the chart, so it loads after highcharts.js loads. There are no javascript errors, but there is also no change to the chart what-so-ever.  The chart is generated via JSON data.

Any ideas on what could be going wrong would be greatly appreciated.

Unfortunately it is on an internal site that is behind a firewall.  What would you do to analyze, where would you start?  Could it be a plugin conflict?

I deactivated every plugin except wpDataTables and it still doesn't work.  So I assume a plugin conflict is not the issue.

I am running Version 1.7.

At this point I  am just trying something simple from your example like:  

[wpdatachart id=2]

which is a "Basic Column Chart"

here is JSON that I am using:

[{"date_mo":"Jan","date_dow":"Sun","date_dom":"01","initiated_ts":"2017-01-01","app_count":"35"},{"date_mo":"Jan","date_dow":"Mon","date_dom":"02","initiated_ts":"2017-01-02","app_count":"856"},{"date_mo":"Jan","date_dow":"Tue","date_dom":"03","initiated_ts":"2017-01-03","app_count":"638"},{"date_mo":"Jan","date_dow":"Wed","date_dom":"04","initiated_ts":"2017-01-04","app_count":"18"}]

columns used in chart are:

• initiated_ts
• app_count

and in javascript I have

jQuery(window).load(function() {
if (typeof wpDataChartsCallbacks == 'undefined') {
wpDataChartsCallbacks = {};
}
wpDataChartsCallbacks[2] = function(obj) {
        obj.options.chart.backgroundColor = '#F7F7F7';
}
});

Thanks for your assistance Milos in resolving location of javascript.

Back to my original issue, I am trying to display the dataLabels on the graph.  That still doesn't work and I'm sure its something simple I'm doing wrong.

<script>
jQuery(window).load(function() {
    if (typeof wpDataChartsCallbacks == 'undefined') {
        wpDataChartsCallbacks = {};
    }
    wpDataChartsCallbacks[2] = function(obj) {
        obj.options.chart.backgroundColor = '#F7F7F7';
        obj.plotOptions = {
            series: {
                dataLabels: {
                    enabled: true,
                    color: '#FF0000'
                }
            }
        }
    }
});

</script>

I've tried series and bar.

I also tried plotOptions.series.dataLabels.enabled = true (which throws all kinds of errors because its trying to reference null objects).  On the other hand, the above does not throw an error, but also does not display dataLabels.

Nevermind, I got it!

obj.options.plotOptions

duh!

Thanks for all your help!
