@saul_romero,
The legendText was showing NaN because the JSON you were using didn’t had valuey
in the last object.
{"valuex":"2017-02-20 17:44:36"}
Also the legendText had a redundant 0 in front of it, because value
(a number) was concatenated to a string deltaX
.
value = value + deltaX;
You will need to initialize value as an empty string. To format the the legend text you can use CanvasJS.formatDate() with "YYYY-MM-DD hh:mm:ss:fff"
valueFormatString. Please check this updated JSFiddle.
