How can I create a visualization in Kibana that compares the averages of multiple fields on the same chart? I can do it easily in Timelion as a stacked bar graph for time-series data but in this case I don't want it to be time-based, I just want a vertical bar graph showing overall averages.
For example, let's say I have an index of customers, and for each customer there is a field for "NumberOfVisits" and "NumberOfSales". I want to have a chart where the x-axis is a series of different fields, and the y-axis is the average of each field.
If I were doing this in Excel I would just write out my list of fields in one column, and then in the next column have a series of calculated fields based on data pulled from each column of another sheet.
