Chart js mouseout

Help to translate the content of this tutorial to your language! The mouseover event occurs when a mouse pointer comes over an element, and mouseout — when it leaves. These events are special, because they have property relatedTarget. This property complements target. When a mouse leaves one element for another, one of them becomes targetand the other one — relatedTarget.

In the example below each face and its features are separate elements. When you move the mouse, you can see mouse events in the text area. Or that it left the window. We should keep that possibility in mind when using event. If we access event. The mousemove event triggers when the mouse moves. The browser checks the mouse position from time to time. And if it notices changes then triggers the events. That means that if the visitor is moving the mouse very fast then some DOM-elements may be skipped:.

If you move the mouse fast over them, then maybe only the child div triggers events, or maybe the parent one, or maybe there will be no events at all.

Also move the pointer into the child divand then move it out quickly down through the parent one. If the movement is fast enough, then the parent element is ignored.

The mouse will cross the parent element without noticing it. An important feature of mouseout — it triggers, when the pointer moves from an element to its descendant, e. According to the browser logic, the mouse cursor may be only over a single element at any time — the most nested one and top by z-index.

The mouseover event on a descendant bubbles up.

So, if parent has mouseover handler, it triggers:. If you move the mouse from parent to childyou see two events on parent :. As shown, when the pointer moves from parent element to childtwo handlers trigger on the parent element: mouseout and mouseover :. The pointer is still over the parent, it just moved deeper into the child element. If there are some actions upon leaving the parent element, e. To avoid it, we can check relatedTarget in the handler and, if the mouse is still inside the element, then ignore such event.

When the pointer enters an element — mouseenter triggers. As you can see, the only generated events are the ones related to moving the pointer in and out of the top element. Nothing happens when the pointer goes to the child and back.

Transitions between descendants are ignored. But they do not bubble. Here they are in action. As the mouse travels across the elements of this table, the current one is highlighted:. Try to move the cursor in and out of table cells and inside them. We covered events mouseovermouseoutmousemovemouseenter and mouseleave. The browser assumes that the mouse can be only over one element at one time — the deepest one. Also they do not bubble.Determines the animations duration in milliseconds.

The style is a series of numbers indicating line length followed by space length. Determines the drawing function of jqxChart. When the property is set, you can override the jqxChart's drawing. Enables or disables the crosshairs lines. The lines are displayed in line and area series when you move over a data point.

Gets or sets whether the chart widget in enabled or disabled state. Determines if the animations are enabled. When you set this property it will turn on or off the animations for all series in all seriesGroups in the chart.

You can override this property for individual seriesGroups and series. Determines the rendering engine used to display the chart.

Interaction Modes

When the property is not set jqxChart will automatically select an optimal rendering engine depending on the browser capabilities. The seriesGroups property is used to describe all series displayed on the chart. Each series group may have its own Value Axis Y-axis which allows you to have values with different scales displayed on the same chart at the same time. It also allows you to display multiple series types together on the same chart.

For example, you can display all series in one group as lines and the series in a second group as columns.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. The dark mode beta is finally here.

I would like to include some interactive stuff in the tooltip. The problem is that by default, when the mouse leaves the chart canvas, the opacity of the tooltip goes to 0.

I need to override the mouseout event so that users can interact with the tooltip. The official documentation is good, but not comprehensive I cannot find an official answer, so I have resorted to reviewing the open source code and my developer tools. Using Google Chrome's developer tools, I can click on the canvas and look at the event listeners tab. Under mouseout, I see the following:.

Hover I get chart. I can't figure out how to remove the handler, though. I have tried the following after the chart. None of these selectors remove the event listener. Can anyone recommend a way of getting rid of the default event listener, or a way to pass a configuration option to chart. Thanks in advance. For the following example I have used the sample provided on the custom tooltip documentation that are available here. The object that is passed to the custom function, in this case tooltipModelhave a propriety that will be set to 0 when the cursor leaves the hovered item, if we ignore the line that hides the tooltip it will stay visible until you hovered another item.

Easily the most basic method for displaying data that is part of a d3. While typically the title tag is found in the head section of an HTML document and determines the text title that appears in the browser tab when viewing that page, in modern browsers when title tags appear elsewhere in the document as a child of a div or other object with defined dimensions, hovering the cursor over said object will cause a simple tooltip from the browser to appear with the appropriate text.

For the purposes of displaying data in d3. For this example we have a relatively simple pie chart created using d3. We have 3 sections that represent the number of each fruit we have.

When we view this, mousing over a colored slice of the pie will display an in-browser title tooltip showing the count value for each slice.

If you want something that can be customized a bit more than the default in-browser title tooltip, then perhaps a custom div tooltip is the answer. When the tooltip is shown, we can easily grab the data we want to actually display as the text. The most crucial is in the first mouseover event function, where we specify tooltip. The result is some nice customizable div tooltips with the data we passed in. Login Get started free. Get Started with Chartio.

I've scoured the bar chart and event docs which I find a bit confusing and I've been unable to figure out how to act on a mousein and mouseout event when hovering over a Bar chart's bars not the legend!

Currently the closest I've been able to come is utilizing the callback on the tooltip like so:. This solution doesn't work well because without knowing when the pointer leaves the bar I don't know when to flip the bool back.

Related Hot Network Questions.When configuring interaction with the graph via hover or tooltips, a number of different modes are available. The modes are detailed below and how they behave in conjunction with the intersect setting. Gets the items that are at the nearest distance to the point. The nearest item is determined based on the distance to the center of the chart item point, bar.

You can use the axis setting to define which directions are used in distance calculation. If intersect is true, this is only triggered when the mouse position intersects an item in the graph.

This is very useful for combo charts where points are hidden behind bars. Finds the first item that intersects the point and returns it. Finds item at the same index. If the intersect setting is true, the first intersecting item is used to determine the index in the data. If intersect false the nearest item, in the x direction, is used to determine the index.

To use index mode in a chart like the horizontal bar chart, where we search along the y direction, you can use the axis setting introduced in v2. By setting this value to 'y' on the y direction is used.

Finds items in the same dataset. If intersect false the nearest item is used to determine the index. Returns all items that would intersect based on the X coordinate of the position only.

Would be useful for a vertical cursor implementation. Note that this only applies to cartesian charts. Returns all items that would intersect based on the Y coordinate of the position. This would be useful for a horizontal cursor implementation. Interaction Modes When configuring interaction with the graph via hover or tooltips, a number of different modes are available.

I'm creating a graphic with a Doughnut chart that when hover, instead of showing the tooltip info I would like to show other content different from the "value" with animations and outside the graph. The problem is that when I disable the tooltip func, then the Hover function disappears also.

So I managed to generate manually the "hover" state using mousemove but I couldn't work out how to place again the original color when the mouse is not over. MouseOut doesn't work Any ideas? The best way to do this would be to track the active elements and then when the active list changes, remove the hover style from the old elements before changing the new elements.

In v2 this is has been supported via separating the hover style from the tooltip display so that both can be individually controller. Skip to content.
