TeeChart Get Series Y value or index by given X value
问题 I have the following problem: I am using Delphi XE3 with TeeChart and I'd like to retrieve a Y value or the value index of a serie by a given X value. My serie is a time series with dates on the X axis. I know the date on the chart and I want to display the nearest corresponding Y value to this date. Is there any method or function of the TChart or TChartSeries component to achieve this? Or do I need to iterate through the series until I reached the selected date? It is not possible to use
