How to find the remove the decimal places of an 2 averages and display each field as a bar on a bar chart

For the following data,

Date=4 June 2013, Result=Win,Ticks=11,Setup=Range Fade, Risk=10, Target=11 .....and more

I would like to find the average for the Risk and Target fields each and to remove the decimal places. I have written the following query: source="Trading Stats.txt" | search Risk | search Target | stats avg(Risk) as average_risk avg(Target) as average_target which can display the average of each of the Risk and Target fields but I am unable to get the round function to work.

In addition, I would also like to show the data on a bar chart with the average value of the Risk field as 1 bar and the average value of the Target field as the second bar on the same chart.

How do I do so?

Thanks
