The tool tip gets its data from the axis, so to get more precision there you have to change the tick format for the y axis:
y.tickFormat = ',.1f';

Frage
Problem is dimple js treating data values of measure axis (y - cost) as integer where they are decimal values. Any suggestions how to fix this? Here is the jsfiddle: http://jsfiddle.net/Ra2xS/7/
var dim = {"width":590,"height":450}; //chart container width
var data = [{"date":"01-02-2010","cost":"9.7862"},{"date":"01-03-2010","cost":"9.915"},{"date":"01-04-2010","cost":"10.2634"}];
function barplot(id,dim,data)
{
keys = Object.keys(data[0]);
var xcord = keys[0];
var ycord = keys[1];
var svg = dimple.newSvg(id, dim.width, dim.height);
var myChart = new dimple.chart(svg,data);
myChart.setBounds(60, 30, 505, 305);
var x = myChart.addCategoryAxis("x", xcord);
x.addOrderRule(xcord);
x.showGridlines = true;
var y = myChart.addMeasureAxis("y", ycord);
y.showGridlines = true;
var s = myChart.addSeries(null, dimple.plot.bar);
var s1 = myChart.addSeries(null, dimple.plot.line);
s1.lineWeight = 3;
s1.lineMarkers = true;
myChart.draw(1500);
}
barplot("body",dim,data);
