Standard deviation visualized

[KGBOR]

Hello,

I have the below data which contains reported IT incidents of certain issue types at a local company. The request is to show the standard deviation on a monthly basis for the overall volume and per category as well while showing the average of volume and the max/min of the deviation. 

What are the measures that I'd need to create this and what kind of visuals would you recommend for it?

Thank you in advance!

Hello @amitchandak , thank you for the linked videos. How would you go about the differences in the dataset? In the linked video (second one) each line contains the value (distance run/covered by a specific player on a given day summed up) on which the calculation is performed. However in my dataset, each line will only have the value of 1 as the incidents are all counted separately line by line. Thank you!
