There is no question in your report, and so I have to guess: If Marks.Attachment is maCenter then the marks are centered with respect to the data point. In case of a BarSeries, this is the end of the bar (this is where a line series would run, if the BarSeries would be replaced by a LineSeries). Therefore this behavior is logical. But I could imagine that you want to center the marks inside the bar. Is that what you request? |
|
|
In case you want centered marks inside the bars of a BarSeries you should have a look at r56416: the new option lmpInsideCentered of TBarSeries.MarkPositions centers all marks inside the corresponding bar. See attached screenshot. Please respond if this answers your question so that I can mark the report as resolved. |

hello wp In fact I used ImpInside before in my application but it's not enough because it's not centered. I used this fuction to centered it ChartPrix_ZMois.Marks.Distance:=68-4*compt;//compt:integer; you can download the demo from this address(if you have an account): https://lazarus.developpez.com/telecharger/index/categorie/79/Lazarus titled: X-parameters to see it. |

lmpInsideCentered is a new value of the property TBarSeries.MarkPositions. It calculates the center of the bar and puts the label at this place. But note that Marks.Distance has a default value of 20; to get perfect centering you must reset this to 0. Please don't link to sources outside the bugtracker. They may disappear at some time and are useless then. And since this one is on a French site and I can't read French, I am lost. And if you even require me to register somewhere I can assure you that I definitely will not look at this code! In order to upload sources here pack pas, lfm, lpr, and lpi files into a common zip which you can upload under "Upload file". But only short demos, I will not take the time to seek through large applications. |

hello wp, because lmpInsideCentered is a new value of the property TBarSeries.MarkPositions, certainly in laz 1.8 RC6. I am satisfied and you can set this as resolved. thanks a lot. |

Well - it is a new feature. Normally, the new version, Laz 1.8, would be fine for it. But it is about to be released soon, and I do not want to take the risk of breaking anything at this time. Did you test the fix? For testing you must install trunk, the developer version. |
|
|
Thanks wp well I am waiting for the new Laz version. |
|
|
Resolving, it works in my tests. |

Hello, Ok you can close it! |

Normally it is the poster who "closes" a report. But I'll do it for you... |
