How to know how many tag in a SVG file

[s-triar]

From the example scadavis change the value of the TAG like sv.storeValue("TAG2", 100 + Math.random() * 80);.

But, How do I know the SVG file has TAG?

If you do not know beforehand, you can call sv.getTagList().

So I must use the SCADAvis.io Synoptic Editor to give TAG to a SVG file because plain SVG file only has path. is that correct?

Yes, you have to use the editor to create markup for linking tag values with svg properties that will be animated at runtime.
