Hello pluricongres.

Can you, please, show me the table from which the chart was made? Also, which chart engine are you using to generate a pie chart, and which settings you have applied to it?

It'll help me provide a better answer to adding the total number of items in the chart. The main idea is to add an integer column, and assign "1" to each row, so you can calculate the sum that represents the total of items. This can also be used in a pie chart, as a grouping option.

To add the SUM outside the table, you simply need to copy the shortcode generated in that column's settings, under Data:

Best regards.

Hello again pluricongres.

If all your totals have the same value ($240), you can add a formula column, and simply set it like "Total"/240, which will return (1). Then, you'll be able to use that instead of Total column when generating a chart, and it will have the number of items when you hover over the chart:

However, adding a SUM to the Formula column is not possible with the plugin, so you cannot add it and use the shortcode to display the sum above the chart.

You can, maybe, modify the Form, and have the users select the quantity, (1, 2, 3...). This field would be rendered as an integer column and can also be used instead of Formula column.

Anything other than that would require the usage of wpDataCharts callbacks. Please note that using hooks or wpdatatable and wpdatachart callbacks requires certain level of programming skills and included support refers only to advice.

Best regards.

Hi again pluricongres.

Exactly - the google pie chart displays percentage - this is default behavior of the charts engine, and in order to change that you would have to implement some 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 resource are available in charts engines API (depends on which one you use). Every engine has different approach of charts settings. In wpDataChart callbacks you have to adopt those settings to wpDataChart object(you can take a look an example for each engine in our documentation and also in Support help center). Huge number of examples for any area of programming you can find on stackoverflow.com(typing your problem in google and of the end add site:stackoverflow.com and google will search only on that website) and also a lot of resource of examples of chart, chart settings and customization you can find 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.

Have you managed to replicate the chart I showed you in my previous reply?

Best regards.
