ShinobiChart ignoring series made of 0s

Question

I'm using ShinobiControls for creating a simple chart. When the dataset is:

@{
   @"Value": @0.0,
   @"Date": @1364828400
 },
@{
   @"Value": @0.0,
   @"Date": @1364914800
  },
@{
   @"Value": @0.0,
   @"Date": @1365001200
 }
]

I receive this error message:

Ignoring range with 0.000000 span
From: SChartNumberAxis at 0xc287030, axisRange = { 0.000000, 0.000000 }, defaultRange = { 0.000000, 0.000000 }, maxRange = { 0.000000, 0.000000 }

and my app gets stuck. No error message. Nothing.

Has anybody seen anything similar?

It seems to me that you have not set range for the axis tied to the Value dimension of your points. Supposing that value is displayed on the Y axis. Try:

SChartNumberRange *yAxisRange = [[SChartNumberRange alloc] initWithMinimum:[NSNumber numberWithInt:0] andMaximum:[NSNumber numberWithInt:10]];
    SChartNumberAxis *yAxis = [[SChartNumberAxis alloc] initWithRange:yAxisRange];
