SVG Panel and displaying strings

I am using Grafana with Influxdb and telegraf and I am displaying data in an SVG panel. I have no trouble displaying the data in the table has a field type of an integer but I cannot display the string fields, they always come through as “null” (although not null in the table or in the query inspector of the metrics tab of SVG.

value.attr({"#text": ctrl.series[4].stats.current}); //no okay, returns null
value1.attr({"#text":“working”}); //okay, displays string
valueNumber.attr({"#text": ctrl.series[5].stats.current}); // okay, returns integer

Thanks in advance!
