Drawing a custom bar chart graph in iOS(PowerPlot vs Core plot)

Question

I have been looking all around the net for open source graph plot framework for iOS, but I am struggling with it as of now. I have worked on an app and used PowerPlot Graph Plot framework http://powerplot.nua-schroers.de/examples/webtraffic.html

I am trying to draw a bar graph chart showing two years at once without stacking each, like in the image below: As you can see there is a problem of resizeing and the scaling isnt uniform. I would like to make the chart look bigger and the y axis be more formatted.

Any suggestions because I always hear about core plot also by which you can achieve such(see below), but all i hear about coreplot is flexibility and customization issues.

Answer 1

You can easily produce a bar plot like that with Core Plot. Give it a try and ask specific questions here on StackOverflow if you get stuck.
