Crash, lineChartView "must implement numberOfPointsInLineChartView" ?

[simonbromberg]

** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'JBLineChartView // dataSource must implement - (NSInteger)numberOfPointsInLineChartView:(JBLineChartView *)lineChartView'

I'm on the latest version (2.2) and I implemented the methods:

• (NSUInteger)numberOfLinesInLineChartView:(JBLineChartView *)lineChartView;
• (NSUInteger)lineChartView:(JBLineChartView *)lineChartView numberOfVerticalValuesAtLineIndex:(NSUInteger)lineIndex;

I tried adding numberOfPointsInLineChartView... but it didn't help and I don't think that method is used anymore...

I must be doing something wrong...

[simonbromberg]

Think I just forgot to set the delegate / datasource.

[terryworona]

Cool! Closing.

[simonbromberg]

Still crashes if I don't have numberOfPointsInLineChartView... was this not switched to verticalValueForHorizontalIndex?

Also wants me to have heightForIndex; wasn't this switched to verticalValueForHorizontalIndex?

Neither of these methods are in the documentation anymore.

[terryworona]

Cool I'll look into it.

[terryworona]

In order to support multiple lines, numberOfPointsInLineChartView was moved over to numberOfLinesInLineChartView + numberOfVerticalValuesAtLineIndex.

There are no instances of numberOfPointsInLineChartView within the library anymore.

Are you sure you have the latest? Are you using cocoapods? Do a fresh clone of the repository and compare the header and implementations of JBLineChartView.

[terryworona]

Also, do a free text search for "numberOfPointsInLineChartView"; it should return nothing.

[simonbromberg]

Yeah, I already checked to make sure I had the latest version, I searched for the old methods and did not find anything, and I made sure I was on the latest version.

Files are identical

How it is printing out the assert 'NSInternalInconsistencyException', reason: 'JBLineChartView // dataSource must implement - (NSInteger)numberOfPointsInLineChartView:(JBLineChartView *)lineChartView' when the text "numberOfPointsInLineChartView" doesn't even exist in the project?

Maybe clean and rebuild? I'm stumped.

[simonbromberg]

Tried a clean, also tried a full delete of the app. No luck. Will try to figure out on my end. Probably my fault somehow.

[terryworona]

Heh, yeah sorry, I have no clue.

[simonbromberg]

Right before the assertion failure mentioned above I get:
*** Assertion failure in -[JBLineChartView dataCount], ~/Pods/JBChartView/Classes/JBLineChartView.m:258

[simonbromberg]

Tried removing and re-adding the pod. No luck.

Tried making a new project and copied the code over, and it works fine in the new project...
