Trendline.xmlright after the chart data:<trendLines> <line startValue='430000' color='009933' displayvalue='Target' /> </trendLines>

Your chart can have multiple trendlines on a chart, so they need to be enclosed within the<trendlines></trendlines> tags. For each trendline, you need a<line> element. We then defined its start value, color and the label to be displayed alongside the trendline. In case your trendline needs to have a different end value, you can define that as well using the endValue attribute that would result in a slanted trendline.
