Center Google gauge

I am not so good in CSS but it seems that the Google gauge is impossible to center (well, at least for me).
I am using a block to set up the chart and it looks fine but when trying to center the block in CSS it does not work with Google gauge but it looks as all other charts react on the CSS, also with C3 and chart.js
The CSS I have tried is

.view-mina-resultat.view-display-id-block_4 {
    display:block;
    margin-left:auto;
    margin-right:auto;
    text-align:center;
}

If there is a quick fix or work arround on this, please let me know.
Thanks
