[syncfusion_flutter_charts] Axis with very small range causes crash

[DrNiels]

Bug description

When trying to create an axis with a very small range, e.g., from 77499.99999999999 to 77500.00000000001, the chart is not loaded. After some wait duration, an error is thrown. In my case, the duration is approximately 30 seconds and the stack trace also looks like some kind of timeout to me.

I use syncfusion_flutter_charts in version 27.1.50

Steps to reproduce

Load the example and wait a bit.

Code sample

Code sample

import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_charts/charts.dart';

void main() async {
  runApp(
    MaterialApp(
      home: Chart(),
    ),
  );
}

class Chart extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => ChartState();
}

class ChartState extends State<Chart> {
  @override
  Widget build(BuildContext context) {
    return SfCartesianChart(
      primaryYAxis: NumericAxis(
        minimum: 77499.99999999999,
        maximum: 77500.00000000001,
      ),
    );
  }
}

Hi @DrNiels ,

We have reviewed your query, and to resolve the issue of the chart not loading when using a very small range difference between two data points, we recommend setting the interval property for the axis. Using this, the axis labels can be created at a specified interval, ensuring the chart renders properly. You may also consider using the decimalPlaces property to control the number of decimal digits displayed in the numeric axis labels.

Code snippet:

primaryYAxis: const NumericAxis(
  minimum: 77499.99999999999,
  maximum: 77500.00000000001,
  interval: 0.00000000002,
  decimalPlaces: 11,  
),

For more details, please refer to this user guide links:

Interval: https://help.syncfusion.com/flutter/cartesian-charts/axis-types#customizing-interval

Decimal places: https://help.syncfusion.com/flutter/cartesian-charts/axis-types#decimal-places

Regards,
Kompelli Sravan Kumar.

[DrNiels]

That doesn't fix the issue in my case. Here's my updated example:

Code sample

import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_charts/charts.dart';

void main() async {
  runApp(
    MaterialApp(
      home: Chart(),
    ),
  );
}

class Chart extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => ChartState();
}

class ChartState extends State<Chart> {
  @override
  Widget build(BuildContext context) {
    return SfCartesianChart(
      primaryYAxis: NumericAxis(
        minimum: 77499.99999999999,
        maximum: 77500.00000000001,
        interval: 0.000000000005,
        decimalPlaces: 20,
      ),
    );
  }
}

The stack trace looks identical as well. But just in case I missed some fine differences, here's the new one:

Even if it would work, I consider setting an interval a workaround until the fix and not a solution, even though a workaround would have been nice as well. In addition, the error occurs as well if I don't set minimum and maximum and the values of a series ranges in a corresponding small range, which would require some additional preparation when using a chart instead of simple dumping the values inside, no matter how small the range.

Hi DrNeils,

We have validated the reported issue, and it's occurring due to a very small difference between the data points. The difference between the data points 77499.99999999999 and 77500.00000000001 is 0.00000000002. This small difference results from the precision limitations inherent in floating-point arithmetic. To avoid this issue, we suggest using an interval property value of 0.01 for the axis.

Currently, we don’t support handling large decimals, but we have already logged a feature request for it in our feedback portal. We will prioritize the features of every release based on demand and priority, so this feature will be available in one of our upcoming releases. You can also track the status of the feature using the feedback link below.

I would consider this a bug and not a feature as it causes crashes. For now, I guess I'll need to handle this special case manually, so my app doesn't crash.

[DrNiels]

I see the tag "Waiting for customer response" is still set. Cann I support you with any more information? Or did you simply forget to remove it?

Hi @DrNiels,

Thank you for your patience. We understand the challenges you're facing. Based on your query, the difference between your data points [77499.99999999999 and 77500.00000000001] is 0.00000000002, which results in an axis interval of 2e-11. This is an extremely small value.

In our current implementation, axis label rendering is handled using Dart’s native num type. However, due to limitations in the Dart, which relies on IEEE 754 floating-point arithmetic, ultra-fine precision cannot be represented accurately. For example, adding 2e-12 to a 14-digit double such as 77499.99999999999 + 0.000000000002 still results in 77499.99999999999. Because of this precision limitation, when the axis minimum and maximum values contain more than 10 decimal places, like in your case, the chart may render axis labels multiple times unexpectedly.

As a temporary workaround, setting a more practical interval can help prevent the chart from crashing. However, we recognize that this is not an ideal solution. Therefore, to address this properly, we have logged this behavior in our internal tracker, and our development team is working to improve support for large decimal precision in future updates.

In the meantime, manually adjusting the interval to maintain app stability.
