Wow, yes that really made a huge difference!

Thank you so much.

Hello again, and thank you for taking the time to look at this. Yes, I also think that ....points out of the screen are affecting the performance I would very much appreciate if you could have a look at it. My main app is a bit more complex than my demo app, and it would save me a lot of "work-aroun...

Hi, 1. Setting DrawAllPoint for this situation could seem like an improvement, but it's not. It might improve drawing speed as (I guess) it draws fewer elements, but the way it draws it (when also scrolling) is absolutely not the way to go. The graph gets very shaky. 2. I'm not sure what you mean wh...

Just noticed that an updated version of TChart was available.
I have now upgraded and tested with the latest version V2017.20.170306 and the reported is issue is still present unfortunately.

Hi, I think I'm experiencing a serious issue with the TLineSeries/TFastLineSeries running on Android. Using Delphi 10.2 Upd 2 and Steema TChart V2016.19.161025. I've put together, and attached, a stripped down multi device demo project demonstrating the issue. What I'm trying to achieve is the follo...

Hi, Delphi 10.1 Upd2, FMX, TChart V2016.19.161025 Not sure if I'm overlooking something here, but try this in designtime: - Add a TColorLineTool to a TChart - In the property editor for the TColorLineTool, set the AnnotationValue property to true to see the Annotation designtime. - Now set the Annot...

Thank you very much for your feedback, much appreciated. 1. Regarding the drawing issue of the characters (ID Codes): I just did a test where I create a second separate series for the ID Codes. It's a TPointSeries with Style set to "Nothing" to not show the point itself. Now I can add (Assign) a Mar...

Hi, Well, that does unfortunately not help me much. Android 7.1.1 is not even available for our Samsung devices yet. I've tested with Android 4.4.4, 5.0.1 and 6.0.1 For both version #4 and #6 I can see the issue. Maybe I can ask if you have any suggestions as to think differently to solve the issue....

Ahh, sorry about the incorrect demo project. Had to strip it down due to size limit on attachments and I must have zipped the wrong project.

Anyway, new project attached.

Hi, Unsure if I should create a new support entry, or continue posting to this thread. My request is related to the current topic so I'll post here, forgive if that's not according to the rules. Anyway, Case: Delphi 10.1 Upd 2 + TChart Pro (v2016.19.161025) FMX on Android. Simple TFastLineSeries sim...

Thank you for your help, I just have a small followup question to the case above:

- Is there a way to set the position of the Mark(s), without having to recalc position in ChartAfterDraw?
(Seems a bit odd to have to run through all Series.Count and to find the Marks in use?)
