QUESTION
I'm trying to use dc.js for a correlation matrix. My data looks as follows:
...ANSWER
Answered 2021-Aug-10 at 15:25There are at least two ways to deal with multidimensional data in dc.js:
- You can create "multi-keys" for the dimension and group, which causes the dimension to filter and aggregate based on two keys instead of one. This is how the heatmap and series chart examples work.
- You can create a group where the values are objects and the aggregation function aggregates multiple values under the keys of the objects.
The second is probably easier to use with the data table, since you then specify an accessor for each column which extracts the sub-value from the group value object.
I guess you are probably not using crossfilter to calculate the correlation matrix, since this doesn't sound like an ordinary aggregation operation amenable to crossfilter's dimension/group data model.
So you probably will want to create a "fake group", i.e. an object that looks like a group but returns the correlation matrix values that you compute.
A template for this function might look like:
QUESTION
I have a line chart created using the dc.js library. The line chart is based on two different corssfilter groups by calling stack method. I don't want to use the default colors dc.js provides. How do I assign colors to these two lines based on the group? Here is the code for my stacked line chart class which I used for my React App.
ANSWER
Answered 2021-Jun-25 at 20:23You can set the color scheme via the color scale.
This is an ordinal scale, so e.g. I tried

Sorry for the title, it is hard to sumarize what I am trying to achieve in one sentence.

QUESTION
I am very new to DC/D3 libraries. I am trying to incorporate DC with ReactJS by having a separate pure JS file that is a reusable D3 component. I am following this example here. Here is the dummy data I am using: json snippet.
This is my App.js:
...ANSWER
Answered 2021-Jun-10 at 20:48Thanks for including a reproducible example. It's really hard to debug D3 and dc.js code by just staring at it without running it.
The problem here is that the scatter plot expects the group keys to be a two-element array of numbers, not just a single number. You can see that the key_function(), in the regression example which you started from, returns a function returning such keys.
Changing your dimension accordingly:
QUESTION
I have been working with dc.js for a year now. Recently I have been tasked to implement a pie chart as below:
I want to replace the text labels in the pie chart slices with appropriate images.
I saw this implemented in pure d3.js. Can someone help me translate the implementation to dc.js?

Answered 2021-May-02 at 14:35I took the fiddle and added a couple of 'Meteoicons' I found here.
(Of course, those icons are taken as an example and I have no permission to use them commercially)
The icons are stored in a separated elements. To render an icon, just select its root element and copy its content to another you create in your piechart:
QUESTION
In the dc.js Nasdaq example, percentageGain is calculated as:
...ANSWER
Answered 2021-Apr-27 at 04:14I agree that Equation B is easier to define using crossfilter, so I figured out one way to do it.
Equation A could probably work but it's unclear which day's close should be used under filtering - the last day which is not in the current bin? The day before the first day in the current bin?
Equation B needs the earliest row for the current bin, and that requires maintaining the array of all rows for each bin. This is not built into crossfilter but it's a feature which we have talked about adding.
The complex reduce example does this, and we can reuse some of its code. It calculates the median/mode/min/max value from the arrays of rows which fall in each bin, using these functions to generate those arrays:

QUESTION
I'm creating an interactive map for office locations to make it easier for clients to reach out to the nearest office. I use HTML file, CSS file, and JS file together for this map. Everything works fine except when your point out a location on the map, information about the nearest office should popup on the right side of the screen. This information includes a hyperlink to the office's website. The problem is that the hyperlink looks fine (blue and underlined) but it is not clickable. I mean the link does not work.
I tried all possible solutions to solve that. Can you help me? Thanks in advance.
This is the HTML file

QUESTION
I have a basic dataTable in dc.js. I'm trying to get it to display a list of all the values in the data. But instead it shows a subset. Very simplified Fiddle here: https://jsfiddle.net/dhbrt0om/1/
...ANSWER
Answered 2021-Jan-10 at 12:28Ah, I see this is because every field needs to have a value. It's actually listed in the crossfilter gotchas wiki: https://github.com/crossfilter/crossfilter/wiki/Crossfilter-Gotchas
If the key function returns undefined for a single row, say due to a missing field, this can corrupt the entire index.
