Qlik is not really relevent here I guess but I will mention it anyways. I had a similar issue with the datalabels plugin, but it was solved by the mapping in the above code snippet.
This is coming from line 11 here. Any help on how should I require this plugin to overcome this error? I have tried to search for a solution with no luck so far. Thanks in advance.Install pgcrypto postgresql 10
We also had a similar issue. We had tried endlessly to attempt the owners solutions however to no avail. The issue occurs since RequireJS expects libraries to omit. Regarding the error on line 11, we also replicated that issue and our conclusion was that chart was not loaded correctly.

You can call chart. See this example on jsfiddle. And it looks like:. However, I don't want to show the Reset zoom button in the first place. Instead, I would like to hide it first, and then listen for a zoom event In chartjs-plugin-zoom the event is mouse wheel and pinch for touch screens to show it.
So the question is, is there a way in chartjs with chartjs-plugin-zoom to add a zoom event handler wheel and pinch events to a chart? Unfortunately, you can not add mouse scroll event to the chart, as the chartjs-plugin-zoom will prevent that by default.
So each time you zoom in the reset zoom button is displayed and once you reset the zoom it is hidden again. Learn more. Add zoom event handler to charts for chartjs with chartjs-plugin-zoom Ask Question.

First, you should apply a style to the zoom button that will have it hidden by default. Nikos Steiakakis Nikos Steiakakis 5, 6 6 gold badges 42 42 silver badges 51 51 bronze badges. Sign up or log in Sign up using Google. Sign up using Facebook.

These are available on all charts created with Chart. Use this to destroy any chart instances that are created. This will clean up any references stored to the chart object within Chart. This must be called before the canvas is reused for a new chart. Triggers an update of the chart. This can be safely called after updating the data object. This will update all scales, legends, and then re-render the chart.
Note: replacing the data reference e. Prior that, replacing the entire data object could be achieved with the following workaround: myLineChart. A config object can be provided with additional configuration for the update process.Exhibition design rfp
This is useful when update is manually called inside an event handler and some different animation is desired. Reset the chart to it's state before the initial animation. A new animation can then be triggered using update. Triggers a redraw of all chart elements. Note, this does not update elements for new data. Use this to stop any current animation loop. This will pause the chart during any current animation frame. Use this to manually resize the canvas element.
This is run each time the canvas container is resized, but you can call this method manually if you change the size of the canvas nodes container element. Will clear the chart canvas. Used extensively internally between animation frames, but you might find it useful. Returns an HTML string of a legend for that chart. The legend is generated from the legendCallback in the options. Calling getElementAtEvent event on your Chart instance passing an argument of an event, or jQuery event, will return the single element at the event position.
If there are multiple items within range, only the first is returned. The value returned from this method is an array with a single parameter.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Like in the line graph for bar charts, is there option like that? It's very urgency for me. Thanks in advance. It's really more about just scaling the values of your chart in fractions. JamesWilsonNovel I'm using ChartJS and would that the user rotate the mouse wheel on the chart, it is capable of zooming. I tried to do something like JamesWilsonNovel but then I tried google charts.Sports stats excel template
Google also forces you to call their API, so code is not self-contained. I love Chart.
From the perspective of the chart, zooming is essentially 2 things:. In terms of triggering zoom, I don't know how much we'd put into the core. I think we would create an extension that would add that functionality. The extension could have dependencies like HammerJS for gesture support and other advanced things that we don't necessarily want in the core. While I know you, and others, are always expanding it and improving it, when trying to decide on which library to use it would be handy to have a changelog with some dates to see a timeline of features that have been added so they can project into the future that maybe within a short period what they want would be supported.
That could entice extra users, which could mean extra contributors as well. As it stands now, I would have to dig through a graphical chart on github hovering over a bunch of different things trying to decipher what has been added in a timeframe. Not the worst, but maybe not as helpful as a changelog with a "coming soon" in v2 section. I really like Chart. As I'm new to this project maybe you guys could provide some feedback on my way of integrating the timeline into the infrastructure.
As you mentioned you don't want the core lib to be too cluttered with stuff that's not used very often, so I thought about creating the timeline as a plugin. Unfortunately I needed some places of the core to change handleEvent method for example. So guys?Maven exit code 127
Now I see version 2. Is this supported now? I would really appreciate an example of panning and zooming a plot. Panning means dragging changing the x scale values? I am not able to get it running. Zoom works, but it zoom only the numbers instead of a string labels. Does someone know what could be the issue? Can this be closed? A suitable solution has been presented with the Chart.
Have you tried the demo? It keeps sending the wrong event which leads to just being able to zoom in, not out.Have a question about this project?
