Hi, Cassandra

- 

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

- There are a couple of important details to double-check, which can affect this kind of behavior with the floats not properly showing, as we can see on your screenshots.

Let's try with some easy checks first, and we will proceed as needed.

I see on one of the screenshots, in the table, you have a dot on the floats as the number format.

And on the other screenshot, where it is not properly showing on the chart, you have a comma.

So, can you please try changing this number format here, in the plugin settings; and tell me if that resolves it?

- Please contact us further immediately if it is still not resolved, and we will see what to do next.

If you want to save some time; you could provide me a temporary WP-admin (administrator) user 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 parties. 

You can write credentials here just check PRIVATE Reply so nobody can see them except us.

And point me to the table ID which you use for data source of the charts; if you could tell us both table ID's, from those screenshots, and chart ID's... as well as the pages where they are, and we will take a closer look for you.

Hello Cassandra

Unfortunately, we do not provide live support.

Chart engines do not follow wpDataTables formatting, so you will need to include some wpDataCharts callbacks in order to display the desired number format.

You can take a look at this FAQ thread, where you can see how we've changed the number format in a Highchart using a callback.

• 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 the Support help center). A 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 a certain level of programming skills and included support refers only to advice.
