Modularizing Duplicate Code

[johncblandii]

I'm making numerous tweaks to the charts and I have the MSArea2DChart doing what we need but now we need the MSLine2DChart to do it too. I'm going over code and things like drawing labels, vdivlines, etc looks to be line for line exact.

So, my request is to better modularize common functionality into utility classes or just put them in a common parent class. This way if people buy the source, like we did, someone poor soul, like me, doesn't have to make changes to every chart source file to fix the staggering logic. :-(

Thanks.

Hi John,

 

 

 

For each chart, the common functionality has been grouped in hierarchical parent structure (Chart > SingleYAxisChart > ...). However, in many cases there are similar functionalities having minute differences, in which case we've to port them to individual classes.
