I used the following lines to plot a heatmap with plotly in R:
plot_ly(data, x , y) %>% add_trace(type='histogram2dcontour')
I then obtained the following plot
The data actually looks like that on a scatter plot
As you can see, I lose a lot of points on the heatmap. I was wondering how I could manually set the scale for the colour of the heatmap for e.g. making it so that the colour changes every time the count increase by 10 instead of 100.
Otherwise, is there a better way to plot and visualize such data?
