Great idea! I would love to see the production statistics report get some love; my priority request list in order (explanations below):
A) Option to sort the report by net production
B) Option to align items in the report (so the row for an item shows production and consumption and net production)
C) Option to hide the graph and only see the numbers, or only see graph and hide numbers
D) Maintain the report state (selection of time period, selection of view (items vs fluids vs buildings), any other options)
E*) Add time to depletion of quantity on hand (QoH), and the option to sort the report by time to depletion
Explanation of benefits and reasoning:
A) Sort by net production: Most of the time when I open the report, I want to see if I am running out of items. Yes the current report allows me to select an item like say plastic and check that it is okay. Two thumbs up to the suggestion to add the net production to the report! It would be even more useful for the report to be able to show me in order which items are being depleted the most. As an added bonus, if the report is sorted by net production, it will automatically provide my second request, to align all the data for one item together in the same row!
B) Align items in the report: Again, I want to compare how much of an item I am producing against how much I am using. Having the production and consumption on somewhat randomly different rows in the report (especially if I have to scroll to find it) makes it harder to find and compare. It would be very useful to have the information on one item collected together in one nicely aligned row. I know I can filter the report to get one item, but if I want to check every single item I am producing to see if I am running out of any of them, the filter doesn't help.
C) Option to hide the production graphs: I personally do not find the graph useful in its current form, so I focus on the item numbers. I don't mind the graph being there, but I don't use it. Having the option to hide it would free up some screen space on my laptop, so less scrolling to find the item I want to check.
D) Maintain the report state: On opening the production statistics screen, the default time period is 5 seconds, so the numbers change every second, so the report jumps around like crazy, so I do not have time to find the item I want let alone read its current value. So I always change the time frame; it would be a nice to have quality of life improvement not to have to change it every single time I open the screen. In addition, if I do find a problem say with production of petroleum gas, I go fix the problem then go back to the report to confirm that I have fixed it enough. Again, it isn't a big deal to flip through setting the time frame and switch from items to fluids, but gosh it would be nice if I didn't have to do that.
E*) I have listed Time to Depletion of Quantity on Hand last only because it means collecting data that currently isn't reported, namely the quantity on hand. Each item currently has a count of what has been produced, and what has been consumed (the basis of the production report). This proposal would add a count of what is currently on hand; very simple, when an item is produced, the QoH is incremented by one; when one is consumed (or destroyed), the QoH is decremented by one.
The production statistics report, in addition to the suggested addition of net production, would add the QoH and a calculation of the estimated time to depletion of the QoH. Very simple formula: Time to Depletion = QoH / net production loss per minute. So for example if I have 40K on hand, and I am losing 5K/minute, I have estimated 8 minutes until I run out. Again, not looking to know where the QoH is, or if it is actually available to be used. It is up to me to know that 10K of my QoH is parked in a chest at a remote base, so I really only have 30K available, so I only have 6 minutes to depletion, but the report gives me the basic information to drive what I do first.
The main benefit comes when I can sort the report by time to depletion. Easiest to explain through an example: say my biggest net production loss is iron ore, at 40k/minute. My QoH is 4M, so time to depletion is 100 minutes, over an hour and a half; yes I will want to fix it, but I have time to make adjustments. If the list is sorted by net production, plastic may be way down the list, with a loss of only 600/minute. However, if my QoH is only 700, I only have 1.1 minutes to get it fixed before I run out!
Thanks again to the devs for all their great work, and to the Factorio community for all these great ideas!
