I am new to FMX forms and have made a simple health monitoring UI app for iOS. I would like to show the user data over a period of some time in a bar chart form, which would look appealing also. I do want the grid lines behind the bar chart and would like to make it more flat, not 3D.
Are there any exiting third party plugins or library API that I can use in my application? I would be willing to buy a license for it too.
An example bar chart would be something similar to the default in-built iOS app for health monitoring - healthkit.
Another option would be such UI kits, would these be available for integrating with FMX?
Any help is appreciated. Thanks!

Yusuf Husainy.
Have you checked out the TChart component that comes with Delphi? There is also a pro version that has more capabilities. Check out https://www.steema.com/product/vcl (the URL says "vcl" but TChart is available for Firemonkey too). You should be able to make charts like the ones you want with it.

I'm trying to improve the accessibility of my Delphi made application to vision impaired users. My application uses many custom GUI components. They mostly descend from TWinControl or TGraphicControl.
My custom components seem to be invisible when testing with NVDA. For example NVDA will respond by reading the name of the control (or other details) when mousing over regular Delphi VCL controls such as buttons or forms. By contrast NVDA doesn't respond at all when mousing over any of my custom controls.
How do I make my custom components visible to NVDA and other screen reading software?
Found the answer on the NVDA Design Overview page. NVDA uses a number of accessibility APIs to gather information about GUI controls. NVDA supports:
Microsoft Active Accessibility (MSAA) (also known as IAccessible),
​IAccessible2,
Java Access Bridge
UI Automation
It looks like I'll need to implement one of the above APIs. Not sure what the pros and cons of each API are yet.
Creating Accessible UI components in Delphi provides details on implementing IAccessible. (Thanks for the link David)
I want to make a charting control for an embedded device using Silverlight for Windows Embedded. Currently i am planning to use line shape for drawing the graph.
My question is if its a good approach(performance wise) or should i look for other options.
Or if any controls are available for SWE.
Thanks
Silverlight is not a proper answer to drawing charts on an Windows Embedded Compact device. You should go for using (or creating) a native GDI element. If performance is very important (e.g. for a fast-updating chart), you might also consider DirectDraw.
The best way in a commercial project would probably be to use a readymade component, such as this one.
You can find somebody else's experiences and advice here for pointers to what to look for when doing this yourself. If you expand your post with more details about what you are actually trying to achieve, I might give you a more detailed response.
The answer is stop using Silverlight, since Microsoft is abandoning the product. Do it in Flash—or better yet, use HTML5 and JavaScript.
In recent windows embedded applications that use windows universal apps I would highly recommend oxyplot.

These plots are the best I've found on the internet so far and very easy to use. Best of all they are free. You can get these using a NuGet Package manager which makes getting updates fairly simple.
I need to write a text box control for Metro Style app. And I need that this text box can invokes a touch keyboard, when my app runs on tablet PC.
Microsoft advices me:
If you are writing a custom text control (whether in Xaml or not) you will need to make sure it supports the UI Automation TextPattern and ValuePatterns and focus changed events
and
You will need to provide an AutomationPeer which supports the ITextProvider and IValueProvider.
But I can't to figure out what actually I need to do. I will appreciate any help.
You need to implement a UI Automation Provider; in particular, you need to implement a server-side provider. Start with the UI Automation Provider Programmer's Guide, and pay particular attention to the Document Content Provider Sample, as it demonstrates how to implement TextPattern. There are more samples as part of the Windows 8 SDK, in the samples/ui/uiautomation directory. Also, there's a very quick introduction to server-side introductions here, written by one of the architects of UI Automation.
I want to use ribbon menu(as on Microsoft Word 2007 or 10) in my IPad application. Anyone have any suggestions? If it impossible to implement, may be anyone have other ideas how to implement similar functionality? In IOS development i am newbie, so i can not imagine how to modulate Ribbon menu with Xcode tools. May be using of Ribbon menu in tablet Apps is not good idea, if so, what alternative i can use? Ribbon menu need because application is very large, and it's have many tools and options. Thanks!:)
I would avoid the Ribbon. I am pretty sure it wasn't designed for touch and users will reject the idea of such a distinctive Windows control on iOS. There are other options for complicated options than a Ribbon. Google iPad menu.
is there a vcl or a project (in delphi) that would allow me to download OSM tiles and display them on an app?
I have tried embedding an browser and it worked great but i need a way to display the maps offline.
As I see it, there is 3 ways to do this :
Save all displayed tiles as a single image (could be done easily with a TWebBrowser, or TEmbeddedBrowser component) : you would navigate to the map address (OSM Mapping Server) based on given coordinates (top left corner), and then take a snapshot. You need to recalculate the base coordinates (top left corner) after each snapshot.
You need to understand how tiles are generated, wich is not quite difficult :
basically, the scheme of osm tiles generation is as follow http://osmserver.org/tiles/tile/x/y/z.png
Once you understand how it works, you could calculate tiles url by code and download'em one by one.
For more info on the tiles generation scheme look here :

or if you need to go further : http://wiki.openstreetmap.org/wiki/OSM_Protocol_Version_0.5
download the entire OSM maps (available on the web) and use a VCL component to display them (Tatukgis DK...)

I don't know the OpenStreetMap project very well, but there's a chance that the project itself has the software to "view" the maps inside a page.
You can accomplish your goal: show the maps off-line using the same basic construct you have now for the user interface: a embedded browser.
What you change is the url the browser will connect to to something like (http://localhost:3458), making your application her own web-server, for example, with Indy TIdHTTPServer binded to port 3458 (just an example port).
That way, you can serve the content for the embedded browser from inside your application, in the same way Delphi IDE (>= 2005) itself provides content for the main page you see when you start it (in fact, a embedded web browser).
To that browser, you serve the viewer page, all it's dependencies and the OSM file. The only restriction to this idea is the viewer MUST do all the things on the client side (for example, it could be javascript, flash, etc.). No server side scripts, unless you are willing to "mimic" the server side behavior or to integrate your application with the script engine (not too easy).
Other chance is to use THBImage, who offers OpenStreetMap integration with Delphi and a (not working) site demo.
Oops! I tried to provide a few hyperlinks in my message but as a new StackOverflow user I'm limited to just one. You might checkout the "Need solution to display map" message thread (25-Jan-2010) on: embarcadero.public.delphi.thirdpartytools.general
I'm trying to solve a similar problem. I need to display a county-wide or city-wide map using Delphi and then put custom icons on the map. I do not need routing or a very detailed map. In the past I've used a TMS "hotspot" component for the custom icons on top of a TImage. Now I need a way for the client to select their own map for the static background image.
A freeware MFC GUI control class (with source) which implements display of OpenStreeMap tiles:
www.naughter.com/osmctrl.html
The zip there has an executable that shows how it works.
This unit is to calculate URLs for the OpenStreetMap Project's TileServer, and other useful utilities as may be needed. If you want to use OpenStreetMap in your pascal programs, then this is for you.
http://code.google.com/p/openstreetmap-fpk/
I'm also considering using the free Tiger/Line maps. Those look pretty good in a free Linux program (xastir).
TatukGIS looks very good (and expensive). I certainly don't need a full GIS solution so this seems to be way overkill just to display a map. But if I don't find a simpler solution this still might be better than integrating MS MapPoint.
TGlobe seems like what I need but sadly it is no longer available.
look in StelMAP for Delphi with OSM
Component to view a map of the project OpenStreetMap for Delphi 2010 without using browser or scripts.
You can view maps offline. Support for proxy servers for work online. Multi-threaded loading tile map speeds up the process to download and view maps.
The set of procedures and property allows you to add a component to map an unlimited number of layers, shapes and images.
Don't know about OSM files, but if you can open them in a browser, you can always embed a TWebBrowser in your Delphi application and load the files within it.
Not the most elegant, but should work...(requires IE)
