Sorry for the delay in getting back to you, it’s been a while since I’ve looked at this code and not sure that it will still work.

I’ll try and put together a code sample tomorrow to test it out, I’ll also upload it once I have it all working.

Cheers,
Bert

Hello from Greece,
I would like to thank you for your great code tutorials.
I am now learning objective c and this code is very helpful.
However i have trouble putting it all together.
in the example use block above you say to put the code inside a UIViewController.
I think i have done that but nothing appears when i run it in the device.
I would be gratefull if you could email me a sample project so i can see
how everything is connected. (mythodeia@gmail.com)
Thank you very much

Comment on Line Graph by Bert

Hi@srinivas

Sorry I’ve been really busy, I presume at the moment that you are creating two separate graphs on each with it’s own View? Then placing them one on Top of the other, therefore one is covering up the other?

Correct me if I’m wrong.

What you will need to do to create a combined bar / line graph is combine parts of the line graph class with the Bar Graph code.

The draw code should follow these simple steps:
• Render the Graph Background and Text
• Render the Graphs Bars
• Render the Graphs lines over the bars

By doing it this way all the objects are rendered onto the same context permitting both the bar and lines to be seen.

Please find the developer documentation on rendering into the context here:
http://developer.apple.com/mac/library/documentation/GraphicsImaging/Reference/CGContext/Reference/reference.html

Sorry I can’t be of much more help at the moment, if do eventually build a combined Bar / Line graph I will post it though I currently have no need for one.

Good Luck,
Bert

@Bert
Thanks for the tip. I also realized similar solution for scroll thing. But, I wonder was wondering how to make leftmost vertical grid and vertical axis static/fixed when graph is scrolled horizontally.

Thanks.

PS: Avoid my last comment wherein I pointed out the bug for single bar in bargraph. Its actually defined behavior I realized later.

@ashok
Sorry need to fix the links, if you pull the code out off the sample project it should at least work

If you want a scrollable bar graph you will need to do a bit of rework, I think your best bet would be to add a scroll view as a sub view in code and then move the bar rendering into that view. Thats just off the top of my head.

If your having trouble doing this do let me know and I’ll try and throw some sample code together, though I’m currently quite busy finishing off a product.

Cheers.

Your code completely suits the need of my app. Thanks man!!
I added BarGraph view as the subview and did little tweaking in initialization code of bar graph and bar width implementation (at 3 places) in drawRect().

[self.view addSubview:barGraphView];

But now I’ve to implement horizontally scrollable feature when there are more bars in the graph than what screen can accommodate? I don’t know how to implement scrollable feature for a view (rather subview in this case).
Actually the bar graph is the only view for this screen, so I can even add it as the main view but I would prefer it as subview of main view.
Any help?

PS: Bert, the BarGraph behavior is not correct (bug) when there is only one bar in bargraph.
