sdGraphManager
|
||
|
|
This is still WIP
|
||
|
|
A basic class to manage named graphs
|
||
|
|
Multiple data sets can be managed in a single graph
|
||
|
|
|
||
|
|
TODO:
|
||
|
|
+Graph layout on screen
|
||
|
|
+Expose a way to adjust graph size
|
||
|
|
+More efficient drawing than using deviceContext
|
||
|
|
+Labeled axes
|
