What options are there for charts on iOS?

I’m guessing Chart Director does not work, because the MBS website says “Works with Mac OS X, Windows and Linux for Desktop, Console and Web.”

So, are there any options apart from doing charts from scratch?

HTML & CSS and load it into an HTML Viewer

You can load a local URL

  dim f as FolderItem
  f = SpecialFolder.Documents.Child("test.html")
  dim t as TextOutputStream = TextOutputStream.Create( f, TextEncoding.ASCII )
  
  t.write "<html>"
  t.write "<head></head>"
  t.write "<body>"
  t.Write "hello"
  t.write "</body>"
  t.write "</html>"
  
  t = nil
  
  HTMLViewer1.LoadURL f.URLPath

There is always google charts

google charts requires you to send them your data

if you write the html and css into a file locally you can do this completely offline

I see… well then. Thanks.

I’m in need of polar charts , too. Looks like this won’t be easy.

Depending on your needs, you could probably do this with iOSPath and iOSGraphics. Pie and bar chars should be pretty easy. Check http://developer.xojo.com/iospath

I would love to write a ChartDirector plugin, if Xojo would let me link in my static library into your app.

Triple-A+

So, how do we get them to allow that?

I want this very, very much.

Or a Shinobi Controls Plug-in, if anyone could do that…(doubt it, I guess)

We have to wait until they have time to do it.
Currently iOS has so many things which need fixes or enhancements…

This I can believe. Hopefully, they’ll get the fixes done Monday and the enhancements done Tuesday, so we can have the charts by April Fool’s Day.

Kidding aside, I look forward to the day we have charts on iOS.

Would some of you be interested in ChartView for iOS ?

It currently works for Desktop and Webapps but I could update it for iOS if requested:

if the web one is all html / css & js it would probably work fine already IF you can output the chart to a file that can be loaded into an htmlviewer. That’s kind of what I was alluding to in my first reply.

Do you have polar charts and guages by chance?

I am still working on implementing Polar Charts, on of my current projects will need this type of charts in a couple weeks.

I don’t have any circular gauges for the moment, but it would be fairly easy to add.

Just wondering if there are any new iOS third-party chart options I should explore before rolling my own? Anything changed since this thread started?

Yes. Please!

Unfortunately I am very busy on other projects at the moment, and none of them needs a Chart control.

Old thread, just trying to motivate you :wink:
