I'm looking to render a trendzone from a value I know up to the maximum value charted on the y-axis.
e.g.
datasource.trendlines.push({
line: [{
startvalue: 5,
endvalue: #The top of the chart#,
displayvalue: rangeName,
color: rangeColour,
showontop: 1,
istrendzone: 1
}]
});
How can I get the dynamically get the max value of the y-axis? I know I can set the max y-axis value but I'm looking to retrieve the value FusionCharts automatically sets when you don't specify a max
Many Thanks,
Odhran Hardy
