Trendlines are the horizontal lines spanning the chart canvas that aid in interpretation of data with respect to some previous predetermined figure.

startValue=’NumericalValue’
The starting y-axis value for the trendline. E.g. if you want to plot a slanted trendline from value 102 to 109, the startValue would be 102.
endValue=’NumericalValue’
The ending y-axis value for the trendline. E.g. if you want to plot a slanted trendline from value 102 to 109, the endValue would be 109. If you do not specify a value for endValue, it will automatically assume the same value as startValue
color=’HexCode’
Color of the trendline and its associated text.
displayValue=’StringValue’
Displays a string caption for the trendline by its side. Example: displayValue='Last Month High'. When you don't supply this attribute, it automatically takes the value of startValue.
Thickness=’NumericalValue’
Thickness of the trendline.
isTrendZone=’1/0’
Whether or not the trend displays a line, or a zone (filled colored rectangle).
showOnTop=’1/0’
Whether or not the trendline/zone is displayed over other elements of the chart.
alpha=’NumericalValue0-100’
Alpha (transparency) of the trendline.
