Build a Website

I do have a website and I am trying to create a Line Flot Chart with multiple series getting the data from the data base. This is the table I have in my database: Code | Date/Time A | 9-10-2016 09:25 B | 10-11-2016 10:11 C | 11-10-2016 14:23 A | 9-10-2016 10:10 B | 10-11-2016 11:00 ........ and more entries for same code in same days... So, I need to show in the chart the total number of occurrences for each "Code" for each day. In the above table I have 2 occurrences for code "A" for 9-10-2016, 2 occurrences of code "B" for 10-11-2016 and 1 occurrence of code "C" for 11-10-2016. I don't have problems creating the flot chat but I am not able to get the proper data into the variables for the time series in the flot chart. So, I need to extract the data form the database using mysql and php and pass it to the javascript variables for the Flot Chart??? Attached is the code of the Flot chart that I have for one line serie and I need to add all series available in the database, so it could be 10 or it could 100. I have var d1 and I guess we need to add dynamically d2, d3, d4.... and then pass it to the "var data". These what I need: 1. Create the query to extract the data form database using mysql getting the total numbers of entries grouping by Code and date. 2. Pass the data to the javascript variables to create the Flot Chart
