D3 axis tick labels

Keep in touch and stay productive with Teams and Officeeven when you're working remotely. In a chart you createaxis labels are shown below the horizontal category, or "X" axis, next to the vertical value, or "Y" axis, and next to the depth axis in a 3-D chart.

Your chart uses text from its source data for these axis labels. Click each cell in the worksheet that contains the label text you want to change. To keep the text in the source data on the worksheet the way it is, and just create custom labels, you can enter new label text that's independent of the worksheet data:.

Right-click the category labels you want to change, and click Select Data. In the Axis label range box, enter the labels you want to use, separated by commas. For example, type Quarter 1 ,Quarter 2,Quarter 3,Quarter 4. To change the format of text in category axis labels:. Right-click the category axis labels you want to format, and click Font. On the Font tab, choose the formatting options you want.

On the Character Spacing tab, choose the spacing options you want. To change the format of numbers on the value axis:. If the number format you choose uses decimal places, you can specify them in the Decimal places box. To keep numbers linked to the worksheet cells, check the Linked to source box.

To calculate percentages on the worksheet, divide the amount by the total. Axis titles are not automatically shown in a chart. To add them, see Add or remove titles in a chart. Learn more.

Basically, the idea is to map a numeric variable to the axis.

It is used in most of chart types, like scatterplot or histogram. Here is the code allowing to add a linear axis in a div that has the id res html code not shown here.

Very similar to linear scales above,but applies a logarithmic transform to the input domain value before the output range value is computed. The scaleBand function is ideal to build categorical axis.

It is thus useful for common charts like barplot or boxplot. Here is the Javascript code allowing to add a categoric axis in a div that has the id 'res'. It is sometimes useful to rotate the labels of an axis, especially when this labels are quite long.

Axis titles aren't built-in to D3's axis component, but are essential for a chart. You can add titles yourself simply by adding an svg text element. As shown in the chart below:. It causes the whole coordinate system to rotate. Thus x and y attributes for positioning are really tricky to set up properly.

Note : Check the way margins are handled in this example. This is a very common way to proceed in d3. An interesting approach: overlapping several axis to create complex axis. Basic linear axis with scaleLinear Let's start with the most common type of axis: the linear axis. Log scale with scaleLog Very similar to linear scales above,but applies a logarithmic transform to the input domain value before the output range value is computed.

Categoric axis with scalePoint Here is the Javascript code allowing to add a linear axis in a div that has the id 'res'. Categoric axis with scaleBand The scaleBand function is ideal to build categorical axis.This lets you focus on displaying the data, while the axis component takes care of the tedious task of drawing axes and labeled ticks.

Apply the axis to a selection or transition. The selection must contain an svg or g element. For example:. If scale is specified, sets the scale and returns the axis. If scale is not specified, returns the current scale which defaults to a linear scale. If orientation is specified, sets the orientation and returns the axis.

If orientation is not specified, returns the current orientation which defaults to "bottom". The following orientations are supported:. If the specified orientation is not one of the supported values, the axis reverts to the default orientation. If arguments are specified, stores the specified arguments for subsequent use in generating ticks and returns the axis.

The arguments will later be passed to scale. If no arguments are specified, returns the current tick arguments, which default to [10]. Suitable arguments depends on the associated scale: for a linear scaleyou might specify a tick count such as axis. If a values array is specified, the specified values are used for ticks, rather than using the scale's automatic tick generator.

If values is null, clears any previously-set explicit tick values, reverting back to the scale's tick generator. If values is not specified, returns the currently-set tick values, which defaults to null. For example, to generate ticks at specific values:. The explicit tick values take precedent over the tick arguments set by axis.

However, any tick arguments will still be passed to the scale's tickFormat function if a tick format is not also set; thus, it may be valid to set both axis. If inner, outer are specified, sets the inner and outer tick sizes to the specified value and returns the axis. If inner, outer are not specified, returns the current inner tick size, which defaults to 6.

If size is specified, sets the inner tick size to the specified value and returns the axis. If size is not specified, returns the current inner tick size, which defaults to 6. The inner tick size controls the length of the tick lines, offset from the native position of the axis.

If size is specified, sets the outer tick size to the specified value and returns the axis. If size is not specified, returns the current outer tick size, which defaults to 6.In this section, we will cover the D3. First, we will cover what the D3.

Then, we will generate the D3. Given a data set and D3. The D3. From the earliest math classes, we were told to add axes and labels to our graphs. So of course we will add axes and labels to our graphs and data visualizations.

The reason comes from the two reasons we use graphs: To show a relationships between variables To have the relationship be understood without explanation.

In order to quickly ascertain the right relationship between the data represented, it is useful to have axes. These axes allow us to interpret the relationship between variables.

Is it easy to interpret the relationship between the two circles? As it moves up, is it a linear relationship, logarithmic relationship, or is the graph already inverted so it's actually moving down, or? A large portion of the charts and graphs we build and will cover using D3. For ease of exposition and brevity, we will call the Horizontal Axis the x-axis and the Vertical Axis the y-axis.

When we use the D3. We will refer to this mix of lines, ticks and labels as the axis. When we talk about the x-axis and y-axis, we mean the combined visual elements that represent the horizontal and vertical axis. Before we get into the axis position, axis labels, axis lines and axis tickmarks, we will talk about the scale of the axis first.

The Scale of the Axis tells us the following information: The minimum number The maximum number Whether the scale is inverted What type of Scale we are dealing with: Quantitative Time Ordinal The units of the variable involved Etc Luckily for us, D3.

If you recall the D3. The functions are specific by d3. To generate the simplest D3. The axis variable is named "xAxis" for convenience, you can name the variable what you like. Note - we add the typeof xAxis ; JavaScript to get a feel for what the xAxis variable actually is When we type the above into the JavaScript console, we get the following:.

This shows us that we have created and updated the parameters of a "function".

In case you are not familiar with the typeof JavaScript function: 1 typeof. The "typeof" operator in JavaScript lets you to probe the data type of its operand, such as whether a variable is function, object, string, numeric, or even undefined.

It is important, because we have to call the axis function, passing in a current selection along with any optional arguments. This custom control flow is the same as invoking the axis function by hand, but it makes it easier for method chaining.

It is worth noting that the call operator always returns the current selection. To add the axis to the SVG graphwe will have to call the axis function on a selection.

Three things to note before we go on: The width of the SVG Viewport is units We want to map the numbers of 0 to Now that we have that, we use the. This makes it easier to transform, translate, and style the group as a whole. After we append the group element, we call the xAxis function on the selection.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

How can I create a D3 axis that does not have any labels at its tick markers? Here's an example that shows what I'm afterfrom Mike Bostock no less. There are several Axis objects rotated around the centre, and only the first one has tick labels. Is there a way to avoid their generation altogether?

I'm just going to leave this here since people are likely to end up on this question. Here are the different ways you can easily manipulate a D3 axis. You can increase the distance between the tick labels and the axis with.

You can't avoid the generation of the text elements without modifying the source. You can however remove those elements after they have been generated:. Overall, this is probably the most flexible way to approach this as you can also remove labels selectively.

You can get the data used to generated them from the scale you're using by calling scale.

Without ticks and with tick labels: d3.I had a similar experience back in Good article, but I have a very weird problem, I'm using nvd3 to show a graph with two sets of data, the user can switch from a set to another, triggering the graph update.

Thank you. That is a really good question! I'm not very familiar with nvd3, so I'm not going to be able to give you a straight answer, but If I was troubleshooting the problem, I would look for the point in the initial drawing of the graph when you set up the labels vertically, you will need to set their attributes specifically rotation wise it sounds like you've already done this.

So what you will need to do is perform the same transformation with the appropriate rotation attribute when you update the graph.

I hope that makes sense. I don't know if it will work with your example, because of the differences with nvd3, but if you're still having trouble, post your code onto StackOverflow and ask there.

It's an interesting question and I would like to think that there will be someone much smarter than me who will know what to do straight off the bat. Good luck.

The downloads section is a significant weakness with the information I have on d3. Deepest apologies. It sounds like you aren't running a web server that will allow you to access the additional file. I kind on rely on folks reading the book in some parts to help them along.

Sure is.

It's as simple as getting the portion of code that does the rotating in the 'add x axis' part and duplicate it in the 'add y axis part'. Yow will then need to work out the anchor points, spacing and amount of rotation to suit your graph, but this is pretty simple. Good article. I am trying to add a horizontal text below the x axis but it is not being rendered.

I have added the following code for the xaxis svg. When I add the code that renders the tick labels at an angle, the x axis label text will not be rendered.

How will I be able to achieve both display the tick label at an angle AND display the x axis label horizontally below the slanted tick labels. Apologies for the really late reply. I'm sure that you've figured this out long before now, but I'll answer just in case and if others are interested. Just looking at your section of the code it looks like you have almost combined both the addition of the x axis and the label into a single append.

Thank you so much for this post I know this is an old example but the line You are not accessing the datum or returning a variable to the transform attribute so you could simplify it to. It sure is odd. That's been there for a couple of years! Not just here, but in the book and probably in the example code samples. Great spotting. I feel suitably humbled that my noobishness has been reinforced.

Many thanks I will be correcting directly. And sure enough, it was everywhere.

At a minimum, each axis also needs to be told on what scale to operate. We can also specify where the labels should appear relative to the axis itself. The default is bottommeaning the labels will appear below the axis line. Finally, to actually generate the axis and insert all those little lines and labels into our SVG, we must call the xAxis function. So, in this case, we have just appended a new g group element to contain all of our about-to-be-generated axis elements.

That g becomes the selection for the next link in the chain. That snippet of code above is just nice, clean shorthand for this exact equivalent:. The shape-rendering property is an SVG attribute, used here to make sure our axis and its tick mark lines are pixel-perfect.

No blurry axes for us! We can transform the entire axis group, pushing it to the bottom:. Much better! Yet more ticks are not necessarily better, and at a certain point they begin to clutter your chart. Without clear instruction, D3 has auto-magically examined our scale xScale and made informed judgements about how many ticks to include, and at what intervals every 50, in this case.

As you would imagine, you can customize all aspects of your axes, starting with the rough number of ticks, using ticks :. You probably noticed that, while we specified only five ticks, D3 has made an executive decision and ordered up a total of seven. This is actually a totally brilliant feature that increases the scalability of your design; as the data set changes, and the input domain expands or contracts bigger numbers or smaller numbersD3 ensures that the tick labels remain clear and easy to read.

Time to label the vertical axis! By copying and tweaking the code we already wrote for the xAxiswe add this near the top of of our code. Note that the labels will be oriented left and that the yAxis group g is translated to the right by the amount padding. This is starting to look like something real!

But the yAxis labels are getting cut off. Of course, you could also introduce separate padding variables for each axis, say xPadding and yPaddingfor more control over the layout.
