Hello Wendy.

It seems that your screenshot did not go through, so I'm not entirely sure I understand what you mean. Can you please upload the screenshot again?

Also, please upload a screenshot of the table that's used to generate this chart, so I know what data you're dealing with.

Hi again Wendy.

This is the default behavior of Highcharts - it sees this as Giga, and that's why "G" is there.

In order to change this, you need to add this script to the page where the chart is:

<script type="text/javascript">
jQuery(window).on('load', function(){
    Highcharts.setOptions({
                lang: {
                    numericSymbols:["k", "M", "", "T", "P", "E"]
                }
            });
});
</script>

Custom code needs to be applied to the page where the chart is. Depending on what you're using (Gutenberg blocks, or some page builder), adding the CSS or JS can be done in a few different ways. 

If you need help with adding custom CSS to the page, please take a look at this article.

If you need help with adding custom JS to the page, please take a look at this article.

You're welcome, Wendy, glad I could help.

Please feel free to reach out to us if you have any further questions or concerns!
