I searched for other relevant questions, but either by way of me being new to D3 or just rusty as a coder, I can not figure this out. I've got a graph and I want to be able to zoom in by scrolling the mouse wheel only on the a-axis and the data. Right now, I have the whole graph zooming on the roll of the mouse wheel opposed to just the x-axis.

The translate argument is only the X axis and a 0 value for the Y axis. The scale argument ins only the X axis and a 1 value for the Y axis. Learn more. Asked 7 years, 4 months ago.

Thanks for the input. I'll let you know what I figure out. How about the parameters of the transform attributes?

In examining the source of this example link they have svg and rect declared and I only use graph which leads me to believe I need to somehow compartmentalize how I'm doing this in order to independently scale the x-axis.

Panning and zooming are popular interaction techniques which let the user focus on a region of interest by restricting the view. It is easy to learn due to direct manipulation: click-and-drag to pan translatespin the wheel to zoom scaleor use touch. Panning and zooming are widely used in web-based mapping, but can also be used with visualizations such as time-series and scatterplots.

The zoom behavior implemented by d3-zoom is a convenient but flexible abstraction for enabling pan-and-zoom on selections. It handles a surprising variety of input events and browser quirks. The zoom behavior is also designed to work with d3-scale and d3-axis ; see transform.

You can also restrict zooming using zoom. The zoom behavior can be controlled programmatically using zoom.

Creates a new zoom behavior. The returned behavior, zoomis both an object and a function, and is typically applied to selected elements via selection.

Instead of having to drag horizontally, it would be much quicker to scroll left and right iMovie editor section, e. If scrolling is not an option, at least extending the drag so that it can be given the momentum effect the 'wheel' provides would provide for a better experience in many of the cases I've come across.

For an example of how this works, simply scroll your browser on a page that isn't overflowing horizontally. The page vertically scrolls up and down without any horizontal shift until ample horizontal action is detected and the page budges left and right. Below is is the pattern I've been trying to follow, but I run into a lot of issues trying to set the zoom retriggers the zoom event, setting the offset on the event transform doesn't persist, locking the scaling seems problematic, nested elements don't respond to the horizontal zoom and instead the 'back' on browser history is triggered.

Has any consideration been given to this sort of fx. I tried all day to come up with a solution, but haven't managed it. Any insights would be appreciated. I would probably override the wheel. For example:. A capturing wheel event listener that calls event.

If you want to trigger the zoom behavior within a zoom event, typically you use d3. In the long run, it might be reasonable for the zoom behavior to be more customizable, perhaps supporting multiple modes of interpretation for wheel events. ArcGISfor instance, uses wheel events to pan. Also see Zoom to Brush for an example of zooming to a rectangular region.

Supporting multiple modes of interpretation will probably make the code messy, though, so it might be nice to figure out a better way of encapsulating the logic. A default might be nice. Could it be implemented similar to the dot walking on events that is elsewhere? For example, 'wheel. Closing as I have no immediate plans to add this to d3-zoom.

I have a Dell Studio laptop with a touch pad that is apparently quite sensitive and the seemingly smallest movement of my finger causes my Explorer screen to zoom in or out. I assume this is the touch pad equivalent of Microsoft's mouse scroll-and-zoom function, but it happens repeatedly every time I go online and it is driving me nuts.

You can focus on a particular region using the click-and-drag approach.

In this chapter, we will discuss Zooming API in detail. It is used to apply the zoom transformation on a selected element. For example, you can instantiate a mousedown. It is used to set the current zoom transform of the selected elements to the specified transform. For example, we can reset the zoom transform to the identity transform using the syntax below.

We can also reset the zoom transform to the identity transform for milliseconds using the following syntax. It is used to translate the current zoom transform of the selected elements by x and y values. You can specify x and y translation values either as numbers or as functions that returns numbers.

A sample code is defined below. It is used to translate the current zoom transform of the selected elements to the specified position of x and y. It is used to scale the current zoom transform of the selected elements to k. Here, k is a scale factor, specified as numbers or functions. It is used to scale the current zoon transform of the selected elements by k. Here, k is a scale factor, specified either as numbers or as functions that returns numbers. It is used to set the filter to the specified function for zoom behavior.

If the filter is not specified, it returns the current filter as shown below.

If delta is not specified, it returns the current wheel delta function. It is used to set the extent to the specified array points. If the extent is not specified, it returns the current extent accessor, which defaults to [[0, 0], [width, height]], where width is the client width of the element and height is its client height.

It is used to set the scale extent to the specified array of numbers [k0, k1]. Here, k0 is the minimum allowed scale factor. While, k1 is the maximum allowed scale factor.

Consider the sample code that is defined below. The user can try to zoom by wheeling, when already at the corresponding limit of the scale extent.
