@dpanscik,
Passing stripline label property while parsing the JSON received from the service seems to be working fine. Please check out the code snippet below for the same,
stripLines: [{
thickness: 2,
color: "#555555",
label: "Today: " + jsonData.stripLineLabel[0],
labelFontColor: "#a8a8a8"
}]
If you are still facing issue, kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or Onedrive along with sample data so that we can look into your code, run it locally at our end to understand the scenario better and help you out.
