ThingSpeak

Verfolgen

Hello, I have done this in other environments but I haven't touched MATLAB in years and seeking a bit of direction. I am pushing environmental data to ThingSpeak at a 1 minute interval and one parameter that I am looking to plot is precipitation type. This parameter is coded and utilizes a look-up table as follows: (0) No Rain, (1) Rain, (2) Snow, (3) Rain-Snow, (4) Hail, (7) Rain-Snow-Hail. I used a stacked bart chart in the past. I would query the database, filtered the data by code and created a time series dataset for each code, replaced the original code in the created time series dataset with value of 1 and insert a value of 0 for timeticks that didn't have a coded type value, and plotted each times series dataset. A screenshot of my previous implementation in MACHBASE is attached. Any guidance would be grealy appreciated. Thanks .
