Is there a way to use the tag history binding on a table data property to display hourly or daily totals of tags without using a custom query? I can display hourly/daily averages, min/max, etc, but I would like to display hourly/daily totals (essentially for flows) for production reports. If not what would be the simplest way to query the tag history to produce such tables? I would like to show hourly, daily, and monthly totals if possible (using separate tables), but can limit to hourly and daily only if more practical. ---

Right now you cannot do hourly or daily totals in the binding. In this case you can bring back the natural data to a table and perform sum calculations through expression bindings. So if you had a table with all of the data in it for a given time period you can create an expression like this:`sum({Root Container.Table.data}, "MyTagCol")`in a separate component. You can allow the user to change the time period from one hour to one day or more. ---

This postsounds VERY FAMILIAR… I have been doing some research. Sounds like you and I are looking for a similar function. What I have identified is the ‘area under the curve’ which would be using Reimann Sum. There are some examples that you might google. I have been looking at: [reedr95.github.com/code/2012/11/ … ython.html](http://reedr95.github.com/code/2012/11/26/Visualizing-Riemann-Sums-with-Python.html) I think this would be something that can actually be accomplished with Ignition. I was also given advice that i could inquire about design hours also. I am not against the design hours I just cannot justify a purchase order for it at my company, so I am going to have to beat on the brick wall awhile and find some sort of comparable solution. If you find a solution before I do please re-post. I will do the same. ---
