Hoverover functionality to change the color of bars

plotly.js
1

Hey guys, I have made a basic bar chart using Plotly.js bar chart examples where the data is derived from a CSV file. Now I want to add functionality when we hover over the bars the color changes where and how can I add that, can anyone help me here.

After plotting my graph, I have used the function:
myPlot.on(‘plotly_hover’, function(data){
data[‘data1’] = {‘marker’: {‘color’: ‘#000’}}
})
.on(‘plotly_unhover’, function(data){
data[‘data1’] = {‘marker’: {‘color’: ‘#005587’}}
});

will this work?

Hi @shrutiPlot this example https://plot.ly/javascript/plotlyjs-events/#hover-event does exactly what you want I think, you just need to replace the scatter with a bar plot.
