hi, I am trying to do a time animation of a street network based on traffic numbers. These numbers change every 15 minutes. So my data is for 6 hours having 24 observations (6 x 4) . When I enable time, only dates are detected and not the granular minutes. In my case, since the date is the same, the is no time visualization to see, the vector file remains static. So I am unable to visualize time enabled data. I am attaching the data. I have made a subset to make it easier to look at it. I have intentionally kept the time intervals valid for just one line feature to simply the data. You will see in the data a column "times" which shows the time intervals and a column "flow". I would like that the thickness of the line changes based on the flow value that is varying on these time intervals. Any guidance will be appreciated

Hi I would like to do a one-to-many join from within R. I have an shapefile with N features. I have a table with 12xN records. I would like to join the shapefile with the table so that there is a one-to-many relationship. It is possible to write in R script, to join my table to a shapefile? I am unable to find ways to join data table as one-to-many. Any guidance please. thank you

Thank you Dan Patterson Joshua Bixby Luke Webb I did two different approaches and both worked. Approach 1. I first got a max for the selection, then switched the selection and got a second max, then took max of the both. I felt it was slow, but it works and this switching also updated my labels in display, which kind of confirmed the display of new max assigned to the features. Approach 2. I did not follow the advice of giving a hard coded path, because user can have the file anywhere on the system. So instead, I used layer.dataSource to get the path. Then I used np.amax to get the max of the array (attribute table). So broadly I followed the advice of path and the advice of np.array and also liked the list comprehension technique by Joshua. that also works.

would your solution of accessing a disk file be affected by: 1. lock imposed by arcmap 2. hard-coded path on the file system?

User selects few features, sets their income to max(income in whole of fc) +1 , so now the max of income of whole fc has changed. User goes to another area in the extent, selects a few polygons, sets their income to max(income in whole of fc) + 1, so the max of income in the whole fc has changed again. This continues till all polygons are finished.

Thank you, may be I was not clear. Your code gives same answer as mine. Let me try again. Imagine you have 3 features [0,1,2] in a fc. They have a income field which is an integer [10,12,14] respectively . case1: I have selected no feature selected, I ask for max of fc , I get 14 >> correct case2: I have selected features [0,1], i ask for max of fc , I get 12 >> incorrect, I still want 14, because I am asking max of fc, not max of selection of fc. case3: I have selected features [1,2], i ask for max of fc, I get 14, >> correct I hope it clarifies a bit?
