[syncfusion_flutter_charts] MajorGridLines not drawing correctly

[mariodelriojimenezdam]

When I use a custom axis associated with a LineSeries, Grid lines aren't finished drawing with 25.1.35 version:

With 23.2.7 version it works correctly, this is the code that i'm using:

Axes

CartesianChart

I don't know if there is a bug or if I'm missing something...

Hi @mariodelriojimenezdam,

We have validated your query and checked the reported issue. The issue is getting reproduced when the associatedAxisName is set in the secondary axis. As of now, you can avoid this partial gridline rendering by setting the width property to 0 in MajorGridLines. We have shared a code snippet, screenshot, user guide documentation, and sample for your reference. Please let us know if you have any further needs.

We will fix the reported issue and include the changes in our weekly patch release which is expected to be rolled out on April 16, 2024. We will update you here once the release is rolled out and we appreciate your patience until then.

Code Snippet:

        primaryYAxis: const NumericAxis(),
        primaryXAxis: DateTimeAxis(
          dateFormat: DateFormat.yMd(),       
          ),
        axes: const <ChartAxis>[
          NumericAxis(
            majorGridLines: MajorGridLines(
              width: 0,
            ),
          ),
        ],

Hi @mariodelriojimenezdam,

We would like to let you know that the reported issue is fixed and rolled out in our patch release. We kindly request you to upgrade the syncfusion_flutter_charts package to the latest version below.

Version: https://pub.dev/packages/syncfusion_flutter_charts/versions/25.1.40

Root cause: Gridlines rendering positions are not calculated properly with the associated axis when we map the same orientation of the axis.

If you have any further queries, please feel free to reach out to us.
