Straight to your questions
- I am afraid showing a line when hover over the markers is not supported in Kendo UI Chart. If you wish you can submit this idea as a feature request at our UserVoice portal - this way the community would be able to evaluate it and if the suggestion gains popularity we will consider its implementation for future versions of the product;
- Modifying the position of the Chart's tooltip is currently not supported out of the box. As a possible workaround I can suggest the following approach:
- Hide the tooltip as set visible: false configuration;
- Hook up to the seriesHover event;
- In such event call a function which sets the tooltip with custom position.
).html(kendo.format(e.series.tooltip.format, e.value) +
" - "
//custom position and size
