This sample demonstrates the crosshair behavior in chart. Crosshair is used to inspect or focus on an individual data point. You can customize the axis tooltip using crosshairTooltip properties in axis. Hover the chart area to view crosshair and its tooltip. Touch and hold to enable crosshair in touch enabled devices. Injecting Module Chart component features are segregated into individual feature-wise modules. To use crosshair feature, we need to inject CrosshairService into the @NgModule.providers section. More information on the crosshair can be found in this documentation section.
