To render dashed lines in a LineChart, you can use the certainty role: http://code.google.com/apis/chart/interactive/docs/roles.html#certaintyrole
But this is not really the use case that it was designed for. The certainty role is per-data-point, not per-series. There are many options for styling data series: point size, line width, curve type. You can also use the ComboChart and make some series bars and some lines or areas. See the 'series' option for more details. In ImageChart, you can listen to mouseover events: http://code.google.com/apis/chart/interactive/docs/gallery/genericimagechart.html#Events But I don't know if you can get x,y coordinates of the event, without which it might be hard to show a tooltip. Hope that helps. Let me know if you have any questions.
