A graphing (charting) demo app for time-based data

SSGraph / SSGraphDemo

SSGraph is a graphing (charting) library for iOS with a focus on time based data, such as financial data. It uses Core Graphics to do all of it's drawing. It currently supports line and bar styles.

Other features include:

• Auto-calculates axes, including major and minor gridlines
• Live panning of the graph, with axis readjustment on the fly
• Pinch-to-zoom, with accompanying increases in data resolution and smart, x-axis reformatting (years become quarters, quarters become weeks)
• Data resolution requests on-demand, for supporting large data sets (currently uses Yahoo stock history in CSV)
• Customizable styles, so you can specify filled graphs and
• Multiple data sets per graph (for comparing stocks)
• Percent change and value change modes
• Logarithmic Y-axis
• Single point selection, for seeing the value of a specific point
• Annotations, for adding contextual data such as stock splits
• Synchronize multiple graphs to one x-axis (such as a stock price and volume graphs)

A word of warning

Although originally written in 2010, converted to ARC in 2012, and published in 2014, SSGraph is still very much in a "pre-alpha" state, and I don't expect to spend much time maintaining it. If you use it, please be prepared that you will need to make changes to it. It has not been made into a cocoapod.

ssgraphdemo's Issues

Trying to get it running

Thanks for the great repo. I'm trying to get it running on Xcode 8, but none of the data is showing on the screen. Do you have a screenshot of what the bar graph is supposed to look like?

This is what it looks like on my end:

It's fetching the data because I'm getting the log for " Fetching data for url:http://ichart.finance.yahoo.com/table.csv?" but I'm not sure how to debug why it isn't displaying.

Do you have any ideas?

Thank you!
