Callbacks

Reference

There are a number of config callbacks that can be used to change parameters in the scale at different points in the update process. The options are supplied at the top level of the axis options.

Namespace: options.scales[scaleId]

.Options(o => o
    .Scales(s => s
        .ScaleId("y")
        .BeginAtZero(true)
        .Callbacks(c => c
            .BeforeUpdate("onBeforeUpdate")
            .AfterUpdate("onAfterUpdate"))))

BeforeUpdate¶

Callback called before the update process starts.

.BeforeUpdate("functionName")

AfterUpdate¶

Callback that runs at the end of the update process.

.AfterUpdate("functionName")

BeforeSetDimensions¶

Callback that runs before dimensions are set.

.BeforeSetDimensions("functionName")

AfterSetDimensions¶

Callback that runs after dimensions are set.

.AfterSetDimensions("functionName")

BeforeDataLimits¶

Callback that runs before data limits are determined.

.BeforeDataLimits("functionName")

BeforeCalculateLabelRotation¶

.BeforeCalculateLabelRotation("functionName")

AfterCalculateLabelRotation¶

Callback that runs after tick rotation is determined.

.AfterCalculateLabelRotation("functionName")
