I don't think that this is the same bug as 338642. 

git master now contains a short KChart widget test. You may modify
kmymoney/reports/tests/chart-test.cpp as shown below:

  QVector< double > vec0,  vec1, vec2;
-  vec0 << 5 << 1 << 3 << 4 << 1;
-  vec1 << 3 << 6 << 2 << 4 << 8;
-  vec2 << 0 << 7 << 1 << 2 << 1;´
+// vec0 << 5 << 1 << 3 << 4 << 1;
+// vec1 << 3 << 6 << 2 << 4 << 8;
+  vec3 << 7 << 7 << 7 << 7 << 7;

and let the app run which shows the mentioned behavior.

Then modify

  CartesianAxis *yAxis = new CartesianAxis (widget.lineDiagram() );
+
static_cast<CartesianCoordinatePlane*>(widget.lineDiagram()->coordinatePlane())->setAutoAdjustVerticalRangeToData(101);

and run again - bug is fixed

then modify again

-
static_cast<CartesianCoordinatePlane*>(widget.lineDiagram()->coordinatePlane())->setAutoAdjustVerticalRangeToData(101);
+
static_cast<CartesianCoordinatePlane*>(widget.lineDiagram()->coordinatePlane())->setAutoAdjustVerticalRangeToData(2);

and compile and run again - bug is not fixed.

If you can confirm please restore bug state.
