hiya

If i have gps data for someone over a 24 hour period. Can i show a bar chart of how much time they were within a polygon over a 24 hour period? 

Id like to say we had people there between these hours but not between these hours and then compare it to other events over the same timeframe in the same polygon?

Thanks

Interesting topic, Rob.

 

I guess there is a number of ways you can do this.

 

1. Time Series in MapInfo Pro v2021 allows you to show records within a specific time interval only

Typically, you’d control the display of the points directly but you could also update a table with polygons based on the number of points inside and then the time series will affect the number of points as you change the time and fewer or more points appear inside the polygons.

 

Something like you can see here below with lightning inside hexagons

2. Another approach is to add 24 columns to your data, one for each hour of the day.

Now you need to update these columns with the number of points for the specific time intervals.

Finally, you can create a bar chart that will show the hours where there were points within the polygons

Instead of counting the number of points, you can also set the column to 1 if there are points within the polygon for that time interval.

 

My number of ways stopped at two – maybe there are more suggestions out there?
