There are two ways to see time trend graphs in Dharma: through 1) collected data (date response) and 2) metadata (real time when data was entered) 

  1. Collected Data 

Let's first take a look at how collected data (date response) can be used as a base question for the time series. 

If you would like to see custom time series graphs in results with one of your own questions as a base question, be sure to include a 'date type question' that will function as your x-axis time stamp. 

See example below. Let's say that I want to track level of school supplies at different schools over time. If I want to actively and manually enter the time for each record, be sure to include a date type question that asks which date this record is for. 

Before, during, and/or after data collection has been completed, you can go to settings-> parameters to change the results section into custom time series graphs. 

This is the default parameters for a one-time survey: 

If I want to enable time series, select 'Yes' under 'Do you want to track data over time?' 

Scroll down and select 'Custom' under 'How often would you like to collect?' and Select 'Collected data' under 'What kind of data do you want to use for your analysis?' 

Also, select time series base question, in this example 'Which date is this record for?' 

You also have the option to choose the frequency of the time series, as well as the aggregator. 

With these settings in place, the results section will now display time series graphs with the selected base question as the x-axis time stamp. 

Since we chose 'average' as the aggregator, the y-axis shows the average number of notebooks, in this case across 3 different schools. 

          2. Metadata

If you would like to see time series graphs with metadata as the x-axis time stamp, select 'Automatic Metadata'. 

Notice there are three options to choose from under ' Select time series base question': 

With these settings in place, we may see a very different graph from the previous graph with collected data as the x-axis. It is up to the user to decide with option makes most sense for their projects.
