1. Hello,

   i need to add some option like:
   hAxis: {minValue: 0}
   I try to put it in:
   $p = array(‘p’=>’hAxis: {minValue: 0}’);
   $dataTable = new DataTable\DataTable( $p );
   Nothing…

   $dataTable->addColumn(‘id1’, ‘label 1’, ‘string’, ‘hAxis: {minValue: 0}’);
   Nothing…

   And in the twig:
   {{ gchart_bar_chart(dataTable, ‘chart4’, 600, 200, ‘Durée des licenses’, ‘hAxis: {minValue: 0}’) }}

   But nothing…

   Is it possible to use options ?

   Tanks.

2. Hi,
   Thanks for using GChart. Here is an example of using the hAxis option with linechart:
   
{{ gchart_line_chart(dataTable2, 'chart3', 400, 200, 'coucou',{'hAxis': {'title': 'Hello', 'titleTextStyle': {'color': '#FF0000'}}}) }}


   so as you can see, options can be passed as an associative array to almost all twig functions. I hope it helps!

3. Hello,

   In pie chart I want to show rows even if the value is 0, how to do that in Bundle?
   Thanks you

4. Hi,
   Did you try to use the `sliceVisibilityThreshold` option when creating the Piechart instance?

   ˋ`ˋ
   // this code was written on a smart phone and was not tested…

   // in controller
   $this->render(‘template’, array(dataTable => …, ‘options’ => array(sliceVisibilityThreshold => 0)));

   // in Twig
   {{ gchart_pie_chart(dataTable, ‘chart1’, 400, 200, ‘title’, options) }}
   ˋ`ˋ

5. Hi,

   I am using your g-chart bundle.
   I want to customize tool tip in column chart, how can I achieve this?

6. Hi Ajay,

   According to Google Chart documentation on Tooltips, you need to have add a column:

   
// in js
dataTable.addColumn({type: 'string', role: 'tooltip'});


   Unfortunately, the PHP class DataColumn does not handle role attributes.

   Can you please open a github ticket here?

   Please feel free to open a PR if you feel comfortable adding that property to DataColumn class (DataTable::addColumn($id, $label, $type) would have to be updated too (optional role param). If not, I’ll give it a try… Please let me know.

   Thanks,

   Saad
