How to add tooltip background in google chart

Question

To apply the tool-tip background in Google chart,I tried the following CSS code

path
{
    fill: #000;
}

But this affected the whole google graph..

How to solve this without using html?

Answer 1

Have you tried to apply for the div.google-visualization-tooltip class ?

And I think you have to also enable the isHtml option on the tooltip

var chart_options = {
    title: 'London Olympics Medals',
    colors: ['#FFD700', '#C0C0C0', '#8C7853'],
    tooltip: { isHtml: true }
};
