Passed the event, an array of active elements (bars, points, etc), and the chart.Ĭalled if the event is of type 'mouseup', 'click' or ' 'contextmenu' over chartArea. more.Ĭalled when any of the events fire over chartArea. Each of these events trigger hover and are passed to plugins. The events option defines the browser events that the chart should listen to for. The following properties define how the chart interacts with events. Similarly, the options can be set in the namespace to independently configure the tooltip interactions. The same options can be set in the options.hover namespace, in which case they will only affect the hover interaction. If true, the invisible points that are outside of the chart area will also be included when evaluating interactions.īy default, these options apply to both the hover and tooltip interactions. Defaults to 'x' for 'index' mode and 'xy' in dataset and 'nearest' modes. If true, the interaction mode only applies when the mouse position intersects an item on the chart.Ĭan be set to 'x', 'y', 'xy' or 'r' to define which directions are used in calculating distances. Sets which elements appear in the interaction.

If (disposing & (components is not null)) Protected override void Dispose(bool disposing) Likewise, chart widget also has some public methods to show or hide the tooltip dynamically such as.

Location = new Point(6 + (int) + 6, (int)h + 6), Flutter Cartesian chart widget provides support for showing or hiding the tooltip dynamically using the public methods. Var size = g.MeasureString(text, chart.TooltipFont) Private SizeF DrawAndMesure(IEnumerable tooltipPoints, Chart chart) Var l = wfChart.PointToScreen(Point.Empty) Location = tooltipPoints.GetPieTooltipLocation(Ĭhart.TooltipPosition, new LvcSize((float)size.Width, (float)size.Height)) īackColor = Color.FromArgb(255, 30, 30, 30) Location = tooltipPoints.GetCartesianTooltipLocation(Ĭhart.TooltipPosition, new LvcSize((float)size.Width, (float)size.Height), chart.ControlSize) Var size = DrawAndMesure(tooltipPoints, wfChart) Public void Show(IEnumerable tooltipPoints, Chart chart) Public partial class CustomTooltip : Form, IChartTooltip, IDisposable

You have to create a new instance of that control when your chart initializes.Īdd a new form to your app named CustomTooltip, then change the code behind as follows: using System You can create your own tooltip control, the key is that your control must implement IChartTooltip and then The code above would result in the following tooltip: cartesianChart1.Series = new ISeries "Ī chart exposes many properties to quickly style a tooltip: cartesianChart1.TooltipPosition = ĬartesianChart1.TooltipFont = new ("Courier New", 25) ĬartesianChart1.TooltipTextColor = (255, 242, 244, 195) ĬartesianChart1.TooltipBackColor = (255, 72, 0, 50) Notice the Hidden position will disable tooltips in a chart.
