UpdateTrend

function UpdateTrend(FB_TrendHmi: TcHmi.Symbol): void

The function UpdateTrend updates a TcHmiTrendLineChart control with the ID Trend_TrendLineChart and displays values. The TcHmiRegion control with the ID Portrait_MainContent_Region is used to check whether the TargetContent property has the value Contents/Home.content or not, since the content on which the TcHmiTrendLineChart control exists can also be reused on the Contents/Home.content by another TcHmiRegion control. By using the function UpdateTrendAxisColors the colors of the curves can be adjusted.
