LineChartSample 8 (Source Code)

BarChartSample 7 (Source Code)

• BREAKING Chart touchResponse classes don't have touchInput and clickHappened properties anymore. Use FlTouchEvent provided in the callback instead of touchInput. Check event is FlTapUpEvent to detect touch events instead of checking clickHappened;

• BUGFIX Fix overlapping last gridlines on border lines problem.
