Hi issacchua,
Thank you for your purchase.


Unfortunately we are aware of this issue and it is in our TODO list for next updates.
Sorry for any inconvenience we will need to fix this and I will let you know when we have the solution.

Best regards. 

Hi issacchua,

In file /var/www/wpdt.plugin/wp-content/plugins/wpdatatables/source/class.wpdatachart.php you can take a look where the all logic is.
First you will need to add a this 

$decimalPlaces= get_option('wdtDecimalPlaces');

And then change it in render data in case there is a float.

Keep in mind that for different chart engines for example Google charts you will need to set and change the code for their tooltips.

I made some custom solution for highcharts so if you are interested we can give you a quote for it.

Best regards.

Hi issacchua,

Yes it is after the case float , it should look like this

case 'float':
    $return_data_row[] = number_format((float)$row[$columnKey], $decimalPlaces, '.' , ',');
    break;

Let me know if you managed to implement it.

Best regards.

HI issacchua

Can you please try to follow this example

in ../wp-content/plugins/wpdatatables/source/class.wpdatachart.php line around line 1713 you will find this code

$dateFormat = ($this->getEngine() == 'google') ? DateTime::RFC2822 : get_option('wdtDateFormat');
$timeFormat =  get_option('wdtTimeFormat');
$decimalPlaces= get_option('wdtDecimalPlaces');

I added this line

$decimalPlaces= get_option('wdtDecimalPlaces');

then in line 1754 change the code to look like this 

case
'float':
$return_data_row[] = number_format((float)$row[$columnKey], $decimalPlaces, '.' , ',');
break;
case
'string':

Let me know the result.

Hi issacchua,

Strange, I change the code just like I told you in the post below and the chart respects the decimal places which are set in wpdatatables settings page. ( attachments)

Decimal places is set to 4 but on the first attachment the number is 234.0100 and because the two zeros in the end it displays like this 234.01.

If you are not in hurry I will ask Milos when he comes from the vacation, he made almost the whole wpdatacharts so maybe he can give you some better solution but for sure this is on our list to implement it for next updates.

Thank you for understanding.
Best regards.

Hi issacchua,

Ok, I will forward this to my team and as soon as we have a proper solution I will get back to you.
Probably next week because all of my colleges from my team are on vacation this week, so I will need some time.

Thank you for your understanding.
Best regards.

Hi issacchua,

Well done on finding the solution, i will definitely note this so we can implement it for future versions and for updating the other charts.

I will try to forward this and add it in 2.0 version so when the beta is out this will be implemented.
Thank you for your suggestions.
