Hello,
I am using Lazarus 1.6.4 in windows. I have an app which collects data from some sensors and generate graphs with the data (TChart); after some measurements, I must change the conditions and follow the pattern of change in the graphs. To mark those changes on my file I insert a new line which marks that point (a comment which is not a data point); however, I want to know how to create a mark of this event in the graphs (a vertical line parallel to the y-ax). Sometimes I need several marks on the same graph so I can not just clear the graph and assume my mark in x=0.
I have been trying inserting a new series constant-line to the graph (but I cannot create new lines
), also changing the grid properties (I could not do it), but I think those are not the best options to do it (and are nor working very well). Does someone know or have an idea of how to do it?
Because it is a specific line in a graph I do not have much code to share but I have been trying something like this:
CommentCh.position:=SecondsBetween(now,Temp);
But I cannot insert new lines only changes in the position... anyway I think this is not a good solution or need to be improved...
