We will start by making a time chart grouped by treatment group, then export the JavaScript to use in the next tutorial steps. This example uses the sample study datasets imported in the study tutorial.
Create a Timechart
- Navigate to the home page of your sample study, "HIV Study." If you don't have one already, see Install the Sample Study.
- Click the Clinical and Assay Data tab.
- Open the LabResults data set.
- Select (Charts) > Create Chart.
- Click Time.
- For the X Axis select Visit-Based.
- Drag CD4 from the column list to the Y Axis box.
- Click Apply.
- You will see a basic time chart. Before exporting the chart to Javascript, we can customize it within the wizard.
- Click Chart Layout, then change the Subject Selection to "Participant Groups". Leave the default "Show Mean" checkbox checked.
- Change the Number of Charts to "One per Group".
- Click Apply.
- In the Filters > Groups panel on the left, select Cohorts and deselect anything that was checked by default. The chart will now be displayed as a series of four individual charts in a scrollable window, one for each treatment group:
Export to JavaScript
- Hover over the chart to reveal the Export buttons, and click to Export as Script.
- You will see a popup window containing the HTML for the chart, including the JavaScript code.
- Select All within the popup window and Copy the contents to your browser clipboard.
- Click Close in the popup. Then Save your chart with the name of your choice.
- Before proceeding, paste the copied chart script to a text file on your local machine for safekeeping. In this tutorial, we use the name "ChartJS.txt".
