Is there any way to change default colors of plotly graph

[priyaec98]

Hi , I want to change all graph [Bar chart , multiple chart etc ] colors like heatmap .

renderers: $.extend( $.pivotUtilities.renderers, $.pivotUtilities.plotly_renderers, $.pivotUtilities.export_renderers ), rendererName: "Heatmap", unusedAttrsVertical:false, rendererOptions: { heatmap: { colorScaleGenerator: function(values) { // Plotly happens to come with d3 on board return Plotly.d3.scale.linear() .domain([1,5]) .range(["#d4d4ff", "#f7a8a9"]) } },

                    barchart:{                            colorScaleGenerator: function(values) {
                            // Plotly happens to come with d3 on board
                            return Plotly.d3.scale.linear()
                                .domain([1,5])
                                .range(["#d4d4ff", "#f7a8a9"])
                        }

}, plotlyConfig: { displayModeBar: true, displaylogo: false },

                } 

I have been reading layout documentation , but i didn't get any idea.  

Thanks .
