If you additionally to the y-axis would like to drag data along the x-axis, you may also add dragX: true. To round the values dragged to, simply add dragDataRound: 0 to the config section of the chart instance. The following example configuration shows how individual event listeners callbacks can be configured. Minimum and maximum allowed data values can be specified through the min and max ticks settings in the scales options. By setting these values accordingly, unexpected fast changes to the scales, that may occur when dragging data points towards the outer boundaries of the y-axis, can be prohibited.

To avoid dragging specific data points inside a draggable dataset, you can return false to function onDragStart.

To disable the automatic update of the data, you can return false to function onDrag. Nothing will happen to the points without you changing the data attribute somewhere else. This is useful for frameworks like emberjs who us the data down action up paradigm.

When you drag a point you might want to stop dragging at the closest rounded value, or at a fixed value. In order to do that, specify magnet options you can easily do it:. In order to support touch events, the pointHitRadius option should be set to a value greater than Also note, that mobile devices and thus touch events can be simulated with the device mode in the Chrome DevTools.

Get complete control over drag and drop behaviour with Draggable! Draggable abstracts native browser events into a comprehensive API to create a custom drag and drop experience. Draggable comes with additional modules: Sortable, Droppable, Swappable. Draggable itself does not perform any sorting behaviour while dragging, but does the heavy lifting, e. The additional modules are built on top of Draggable and therefore provide a similar API interface, for more information read the documentation below.

You can easily create reuseable chart components. You can use vue-chartjs directly in the browser without any build setup. Like in this codepen. For this case, please use the vue-chartjs. You also need to add the Chart. Easily build animated charts by leveraging the power of native code. You'll also need to include jQuery before you include this plugin so that jQuery is defined.

And i want to allow user to drag points on chart for dynamically change data of it. I tied chartjs-plugin-draggable but it works for me only with annotations. I need graph exactly like this:. With angular i created something like this.

I didn't find any info too :. Update: My previous answer got deleted because it only featured a link to a plugin solving the issue, however here comes the explanation to what it does:.

In order to intercept the mousedown, mousemove and mouseup events the dragging gestureevent listeners for said events need to be created. In order to simplify the creation of the listeners one may use the d3 library in this case as follows:. On mousedown the 'start' event herea function getElement may be called thatfetches the closest chart element to the pointers location and gets the ID of the Y-Scale.

On mousemove 'drag'the chart data is supposed to be updated according to the current Y-Pixel value of the pointer. We can therefore create an updateData function that gets the position of the clicked data point in the charts data array and the according dataset like this. And that's it! If you need to store the resulting value after dragging, you may also specify a callback function like this. Here is a working fiddle of the above code. The functionality is also the core of the Chart.

Angular 8 Admin Dashboard Panel from scratch using Angular Material, highcharts and flex-layout 🎉🎉

Here is how I fixed using both touchscreen or mouse event x,y coordinates for the excellent d3 example above by wrapping event screen coordinates in a more "generic" x,y object. Probably d3 has something similar to handle both types of events but lot of reading to find out.

And works for both mouse and touch.

Check the Fiddle. Here how I solved the problem with using d3 and wanting to drag the document on mobile or touch screens. Somehow with the d3 event subscription all Chart area events where already blocked from bubbling up the DOM. Was not able to figure out if d3 could be configured to pass canvas events on without touching them.

So in a protest I just eliminated d3 as it was not much involved other than subscribing events. Not being a Javascript master this is some fun code that subscribes the events the old way. To prevent chart touches from dragging the screen only when a chart point is grabed each of the handlers just have to return true and the event. The beginDrag evtduringDrag evt and endDrag evt have the same basic function as in the d3 example above. Just returns true when wanting to consume the event and not pasing it on for document panning and similar.

Try it in this Fiddle using a touch screen. In case anyone is looking for a solution that doesn't require the use of plugins, it's pretty straightforward to do it in vanilla chart.

I'm looking to make 3 points on a graph draggable between 0 and I'm looking to do this in React with ChartJS via react-chartjs Here is a fiddle with everything setup js also below. The fiddle uses some random version of react-chartjs-2 because I couldn't figure out how to import.

Webdev is super new to me. I tried using a few chartjs plugins like this one that claimed to do draggable points, but I couldn't figure out how to get them working in React.

This might be the easiest solutin. If I could get the coordinates and have these events, I could kludge together a solution. I tried searching on the chartjs and react-chartjs-2 docs, but I couldn't find anything that would let me drag, or attach the right listeners. You can do this by using chartjs-plugin-dragData. You have to set dragData: true within options object to use this plugin in chart js.
