Hello Dave

I am sorry to disappoint you, but unfortunately something like this is not possible with the plugin's built-in features.

For something like this, you would need to use wpDataCharts callbacks. 

Available options can be found in Google Charts API, Highcharts API and Chart.js API (depending on which one you use). You can take a look at examples for each engine in our documentation, and also in our FAQ section. Huge number of examples can also be found on stackoverflow.com and jsffidle.net.

Please note that using hooks or wpdatatable and wpDataChart callbacks requires certain level of programming skills and included support refers only to advice.

Hi again Dave

Sure, if it works on jsfiddle, it can be applied through a callback as well. You can take a look at some examples on our documentation and in our FAQ, and see how those xAxis, Categories, series, etc are applied through a callback.

Unfortunately no, Dave.

Callbacks that were tested by us are located in the FAQ section, under "Charts", and we don't have an example of what you're looking for to achieve. If I had anything similar I would've shared it with you.

Like mentioned before, wpDataChart callbacks are not included in the provided support for the plugin, so we don't have a lot of examples.

Hello again Dave

You need to understand that writing custom wpDataChart callbacks (or any code, for that matter) is not included in the provided support for the plugin.

It's mentioned when you access this support platform:

It's mentioned in our documentation about wpDataChart callbacks:

And I mentioned it to you a few times already. So again, unfortunately I can't create a custom callback for you. That's not included in the support provided for the plugin.

The callback you shared in your last response is for a pie chart, and applying different colors on a bar chart is different; applying it to negative bars is different from the callback used for a basic bar chart.

We would offer our paid customization services for this, but our developers are very busy at the moment, working on some priority tasks and fixing bugs and issues with our plugins, so they won't be having the time for custom work in the near future.

But we can recommend these services for customization:

https://wpkraken.io/?tms-plugins

They do develop such solutions, so can you please send your inquiry to them?

Everything we've created has been added to the documentation page, or in the FAQ section.

Most of those callbacks were added when we had time to accept custom work, but since we don't have time for that (and we probably won't for another few months), we no new callback examples are added in there.

We don't know every option that can be used, and we too have to go through the API libraries ourselves, often checking how a segment is changed in jsfiddle before figuring out how it can be applied in the callback. There are a lot of examples in jsfiddle and on stackoverflow.com, so my advice would be to check there as well.
