As I known Kendo renders the old school SVG rather than the HTML5 Canvas, html tags don't work.
So we have to use SVG tags.
but the IE 7-8 browsers does not support svg tspan, so how can I use this?
Old versions of IE (7 and 8) do not support SVG at all, as you can see from this reference. In these IE versions our DataViz widgets provide VML support which you can test on the online demos.
Additionally, on modern browsers you can select between SVG and Canvas rendering, as illustrated here:
