Showing percentages in graphs when using separate option values in the form.

I have to use separate option values in my form in order to be able to filter the graphs the way I need.

So I have an option label like "Satisfied" and a value like "__satisfied__"  

The example below only works for fields where there is no secondary option value - so only "Satisfied" https://formidableforms.com/knowledgebase/frm_graph_data/#kb-show-only-percentages   

In the table produced whenthere ARE secondary option values - the graph data is all set at zero.
If I look at the JS on the page which is generating the graph - the relevant bit looks like ["Satisfied",0],["Unsatisfied",0]] etc etc.

The snippet is targeting the right graph on the page - I can see the tooltip is changing - so it is working - it's just not calculating the percentages correctly.   So I'm guessing there is some mismatch between the php snippet and the label/values when using the secondary option values in the form.  

This is the snippet from the example

add_filter( 'frm_graph_data', 'frm_percentage_graph', 10, 2 ); function frm_percentage_graph( $data, $atts ) { if ( isset( $atts['title'] ) && $atts['title'] == 'Gas by Percentage' ) { $data[0][1] = "Percentage of gas used"; $total = FrmProStatisticsController::stats_shortcode( array( 'id' => 4124, 'type' => 'count' ) ); for ( $i = 1, $l = count( $data ); $l > $i; $i++ ) { $graph_value = 0; if ( $total !== 0 ){ $individual_count = FrmProStatisticsController::stats_shortcode( array( 'id' => 4124, 'type' => 'count', '4124' => $data[$i][0] ) ); $percent = ( $individual_count/ $total ) * 100; $graph_value = round( $percent, 1); } $data[ $i ][1] = $graph_value; } } return $data; }

Does anyone out there with php and Formidable skills know how to make this work - or any pointers I can look into?

Thanks in advance!

Here's a pointer, Formidable's graphing tool is simply an interface to Google's Chart Tools. Anything you can do in Google Graphs you should be able to do in Formidable. Formidable Pro has 11 filters for modifying graphs to your liking. See this: https://formidableforms.com/knowledgebase-category/display-data-hooks/

BTW, if Google Charts doesn't provide what you need, try ChartJS.
