kandi X-RAY | d3-scale Summary

d3-scale is a JavaScript library typically used in Analytics, Data Visualization applications. d3-scale has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can install using 'npm i @thasian/d3-scale' or download it from GitHub, npm.

Scales are a convenient abstraction for a fundamental task in visualization: mapping a dimension of abstract data to a visual representation. Although most often used for position-encoding quantitative data, such as mapping a measurement in meters to a position in pixels for dots in a scatterplot, scales can represent virtually any visual encoding, such as diverging colors, stroke widths, or symbol size. Scales can also be used with virtually any type of data, such as named categorical data or discrete data that requires sensible breaks. For continuous quantitative data, you typically want a linear scale. (For time series data, a time scale.) If the distribution calls for it, consider transforming data using a power or log scale. A quantize scale may aid differentiation by rounding continuous data to a fixed set of discrete values; similarly, a quantile scale computes quantiles from a sample population, and a threshold scale allows you to specify arbitrary breaks in continuous data. For discrete ordinal (ordered) or categorical (unordered) data, an ordinal scale specifies an explicit mapping from a set of data values to a corresponding set of visual attributes (such as colors). The related band and point scales are useful for position-encoding ordinal data, such as bars in a bar chart or dots in an categorical scatterplot. This repository does not provide color schemes; see d3-scale-chromatic for color schemes designed to work with d3-scale. Scales have no intrinsic visual representation. However, most scales can generate and format ticks for reference marks to aid in the construction of axes.

            What is the type of a continuous numeric d3.scaleLinear() scale in typescript
            Asked 2022-Jan-17 at 19:27

            I am passing d3 linear scales into a function using typescript.

            ...

            ANSWER

            Answered 2022-Jan-17 at 19:27

            The first generic in ScaleLinear is Range, and the second is Output.

            Range

            The Range generic is for the type of the range data. If the range is specified in numbers (as in range([1, 10])) the range is of type number.

            If the scale range is specified in strings such as colors (as in range(['red', 'blue'])), then the Range type is string.

            Output

            The Output generic is for the type of data that the scale outputs. If the scale interpolates numbers (as in range([1, 10])), the output is a number between 1 and 10, and so output is also of type number.

            If the scale interpolates colors (as in range(['red', 'blue'])), the output is a color string (such as #9a3439), which is of type string.

            For most cases, you can use ScaleLinear for scales that interpolate numbers and ScaleLinear for scales that interpolate color strings. In those cases where they are equal, you can also use the shorthand ScaleLinear or ScaleLinear.

            How do I create an axis with non-equal tick intervals in D3.js
            Asked 2021-Nov-18 at 21:20

            At the moment, I have a basic scatter plot with linear x and y scales that are used to create the axes i.e. using

            d3.scaleLinear().domain([0.65, 0.78]).range([0, width])

            and

            d3.scaleLinear().domain([0, 1]).range([height, 0])

            in conjunction with d3.axisBottom() or d3.axisLeft() to create the plot. The resulting plot is

            I would like to modify the y-axis such that the intervals between the ticks are not equal e.g. [0.01, 0.05, 0.4, 0.5, 0.9, 0.95, 0.99] while still maintaining the overall size of the plot (no changes in height). Ideally, the plot should end up looking like this (ignore best fit line):

            I've tried using piecewise plotting by mapping domain values to specific ranges (heights) but this doesn't quite work because the height of the plot gets modified.

            Is there a way to create an axis that has unequal tick intervals and still maintain the original shape of the svg?

            The example you are attempting to copy is missing a right ) in the template literal. Even fixing that, though, your markers will be slightly off due to the image not being "centered" at the coordinates.

            D3.js WordCloud: Words overlap and have weird spacing & distribution
            Asked 2021-Jul-10 at 04:44

            I'm fairly new to D3.js and I'm trying to make a wordcloud using Jason Davies' wordcloud library for D3. I'm not sure why the lesser frequent words overlap, and the distribution of words is such that there is a lot of empty spaces in between. I want it more condensed and structured. This is the

            I have seen similar questions here and I've tried a lot of solutions mentioned earlier such as:

            1. Altering svg and canvas dimensions.
            2. Changing the font style like .font('Helvetica')
            3. Using variations of 10 words, 30 words, and 50 words.
            4. Specified a text accessor function like this .text(function(d) { return d.word; })
            5. Exploring options in .padding()
            6. Used .rotate(0)

            Here is my code on JS Fiddle.

            For the sizing of words, instead of the frequency of occurrence of the word, I'm using rank in my code. This is because the sizing gets disrupted due to the outliers in my dataset. Say the highest frequency is 32, and the lowest is 1, there is a large difference between the two sizes as they are proportionally mapped.

            So I opted to size the words based on rank. I have used Javascript to sort this data.

            This is my first question here, so apologies if there is a lack of clarity. Would love any feedback or help/solution to this!
