Hello Adriano.

Thank you for your purchase.

Can you please tell me how the table was created, and if the decimal and thousand separators match what is set up in wpDataTables settings?

That is default behavior of charts engine, but if you need some custom solution you can check in our documentation about wpDataCharts callbacks. 

• Every chart exposes several options that customize its look and feel. Charts usually support custom options appropriate to that visualization. wpDataChart callbacks allow adding options that are available in Google Charts API, Highcharts API and Chart.js API. 

• All necessary resources are available in charts engines API (depends on which one you use). Every engine has a different approach to chart settings. In wpDataChart callbacks you have to adopt those settings to the wpDataChart object (you can take a look at examples for each engine in our documentation, and also in Support help center). Huge number of examples for any area of programming can be found on stackoverflow.com (typing your problem in google and at the end add "site: stackoverflow.com" and google will search only that website). Also, a lot of examples of charts, chart settings and customization can be found on jsffidle.net (typing in google for example "line chart highcharts jsffidle")
• Please note that using hooks or wpdatatable and wpDataChart callbacks requires certain level of programming skills and included support refers only to advice.

I can take a look, but I cannot promise anything,

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. You can write credentials here just check Private Reply so nobody can see them except us.

Best regards.

Hey Adriano.

Sorry, but I couldn't log in with those  credentials:

Can you please check and let me know?

Best regards.

Hello again Adriano.

That worked, thanks.

Number and date formats come from Highcharts, and they do not take any settings from wpDataTables.

However, I've explored the Highcharts API and found a solution for you with some wpDataCharts callbacks. 

Here's what I did. On your page: https://www.agfw-bestand.online/auswertungen/bestandsentwicklung/nettozubau/alle-unternehmen/ I edited the page, and added the callback and the chart shortcode in Classic editor/edit as HTML:

This is the callback you can see in the screenshot above:

<script type="text/javascript">
jQuery(window).load(function(){
Highcharts.setOptions({
        lang: {
            decimalPoint: ','
        }
    });
    if( typeof wpDataChartsCallbacks == 'undefined' ){ wpDataChartsCallbacks = {}; }
    wpDataChartsCallbacks[35] = function(obj){
        obj.options.tooltip = {
            pointFormat: "Value: {point.y:.3f} km"
        };
    }
});
</script>

It changes the decimal separator to a comma, and sets 3 decimal places for all data in the chart.

Please take a look and let me know if this works.

Best regards.

You're welcome, Adriano.

Glad I could help.
