can-i-adjust-the-anchor-of-chart

Yes, you can set any one of 16 anchors but the value use default.

can-display-more-than-1000-data

Yes. But UGUI limits 65000 vertices to a single Graphic, so too much data may not be displayed completely. The sampling simplification curve can be turned on by setting the sampling distance sampleDist. You can also set some parameters to reduce the number of vertices in the chart to help show more data. Such as reducing the size of the chart, close or reduce the axis of the client drawing, close Symbol and Label display. A Normal line chart occupies fewer vertices than a Smooth line chart. The 1.5.0 and above versions can set large and largeThreshold parameters to enable performance mode.

why-are-the-parameters-set-in-serie-reset-after-they-run

what-if-tmp-errors-occur-when-importing-or-updating-xcharts

XCharts does not enable TMP by default, so there are no references to TMP on asmdef. This issue may occur when updating XCharts after TMP is enabled locally. It can be solved in the following two ways:

1. Find XCharts.Runtime.asmdef and XCharts.Editor.asmdef and manually add references to TextMeshPro
2. Remove the dUI_TextMeshPro macro for Scripting Define Symbols in PlayerSetting

Version 3.8.0 after adding Daemon XCharts - Daemon, will be XCharts - Daemon import project, When updating XCharts, the daemon automatically refreshes the asmdef based on the locally enabled TMP to ensure proper compilation.

support-empty-data-how-to-achieve-the-effect-of-line-chart-disconnection

data of Serie is of type double, so it cannot represent empty data. Empty data can be achieved by turning on Serie's ignore and specifying ignoreValue. You can also set the ignore parameter for each SerieData. The ignoreLineBreak parameter can be set to disconnect or connect after ignoring data.

what-are-the-common-problems-when-upgrading-xcharts2-to-xcharts3

1. XCharts.Runtime.XChartsMgr is missing the class attribute ExtensionOfNativeClass! 3.x version does not need to mount XChartsMgr, directly delete the _xcharts_ node on the scene.
