Google pie chart very small but takes big area

I have the following page (please look below), with Bootstrap 4 and Google chart.

There are 3 black boxes, the one at the right has the google chart pie. The problem I have is the area used for the chart is too big compared with the actual chart.

So I configuring the chart with this size:

div id="piechart_3d" style="width: 500px; height: 250px;"></div>

but as you can see, it takes all that space, but the chart is actually half of the size of the area used by that div.

Is there any way to configure this to reduce the area used by that div, but increasing the size of the chart to use most of space 500px x 250px?

Thanks

Solution

  • I found the response: in the option: chartArea: {width: 400, height: 300}
