Hi Mark,

i found an example where we can add one callback for all charts, I will share it with you and I hope it solves the issue.

Depending on the chart engine, the hooks are slightly different, ( basically just tne chart engine name is different for each hook),

they are :

wpdatatables_filter_highcharts_render_data
wpdatatables_filter_chartjs_render_data
wpdatatables_filter_google_charts_render_data
wpdatatables_filter_apexcharts_render_data

I will give you an example for the highCharts engine, and later you can use the same method for other engines/options, you just have to modify the chart engine name throughout the hook.

In the functions.php file of your theme, or child theme; insert this :

add_filter( 'wpdatatables_filter_highcharts_render_data', 'updateHighchartsRenderData', 10, 3 );
function updateHighchartsRenderData ($highcharts_render_data, $chartID, $chart_object){
    $highcharts_render_data['options']['chart']['resetZoomButton']['position']['align'] = 'left';
    return $highcharts_render_data;
}

- This way, it will be applied to all the HighCharts. 

- This hook takes three parameters:

1.  $highcharts_render_data : which is an array with all the options,

2.  $chartID  : in case you need it for only some specific charts; 

3. and the last one is the $chart_object.

-

In that example, we have changed the position of the Zoom reset button of highCharts from right side to the left, but you can modify it to change the options you need for your charts.

-

This will not be affected by the plugin updates, because these hooks will be saved in your Theme's functions.php.

As we noted on the wpDataCharts callbacks Documentation,

using wpDataChart callbacks requires certain level of programming skills and included support refers only to advice.

-

Let me know if this achieves what you needed.

Thank you.

Hi Mark,

you're welcome, i am happy to help.

I am glad to see you found a working solution, at least for the time being, 

I hope you will succeed in making it as you said, as elegant as possible,

but the main thing is that it works.

-

Once you try to implement changing these options,

but just without the HTML <script> tags, and rather adding it in a filter/hook to your functions.php,

you can check out the example our developers sent for the HighCharts and try to modify it as needed,

as well as some other examples from our wpdataChart Callbacks documentation;

At some point when you try, you can reach out to us again,

and we can check with our developers if they are available in that time to take a look if perhaps just a small modification/correction might be needed,

depending on how it goes.

Thank you.
