Hi,
I am using Kibana version 7.4
I want help in creating a scrollable vega visualization.
Use Case:
I would like to show only up to 20 tick values in the x-axis of a bar chart, if a user wants to view more than that he has to scroll the vertical bar and view the remaining.
Sample Vega Visualization code
