Anyone know if there is a way to hide the view finder, while still having the chart display a subset of the data? If I filter the data before sending it to the chart, the chart lines are skewed instead of contiguous.
I'm trying to filter on a date range subset of the data, while keeping the lines contiguous with the entire set of data.
I noticed in the source, on line 362, they filter on !d.disabled. I'm wondering if I can hook into that somehow. Does anyone know the proper usage pattern for this?
The view finder is actually Square's Crossfilter found here [0] if you wanted to browse the source and view more documentation.
However, I would just set the display attribute to none in CSS of the svg containing the crossfilter and be done with it.

I am new to D3.js and have been following examples on this website:
https://www.d3-graph-gallery.com/line.html
I am specifically trying to include a dropdown to filter by a column value and also include a brush for zooming.
The data I am using is simply country, date and covid_cases and I am trying to have an initial monthly line chart that can be zoomed in, while also having the ability to filter by country.
I have taken the code directly from these examples:
https://www.d3-graph-gallery.com/graph/line_brushZoom.html
https://www.d3-graph-gallery.com/graph/line_filter.html
I successfully altered them to fit my data, but am unable to combine them to enable both interactions.
Does anyone have any advice on how I might do this?
I'm using Flot with jQuery to display a graph. I want to update some information on the graph and then re-plot it. I can see that I can use plot.getOptions().yaxes[0].max for example to update the y-axis max value and have got that to work but I'm using a plugin to add side notes to the graph.
I've used getOptions again to update the side notes data and can read the side notes' data, but can't see how I can get the side notes displayed data to update without completely re-plotting the graph.
Any suggestions?
Since you have to redraw anyway, generating a new plot with the new options is the simplest solution. You do not gain much by trying to optimize it (unless you want to redraw every second).
I have a database where I maintain an entity Ids in one table while maintaining a source and target entity on other table.
I have generated a json of nodes and links. and used the following example as a reference (thought it would be enough to only generate the json file):
Force directed graph for D3.js v4 with labelled edges and arrows
Same code with my generated data
The issue is that the graph is messy and I can't infer anything by looking at it. so what I'm trying to do is, since I am familiar with the relations between the entities I would like the nodes to be ordered top down by labels by some certain order. e.g siteref -> ro -> ba -> gr -> ca
Is that achievable at all? I have looked around for some other examples but did not find anything that could suit my needs.
You can add forceY, and optionally pass it a strength. In the forceY function you can set to return 0 for siteref, 100 for ro, and so on. Then you can tune in at your needs by playing a little bit with the strength in the links and in the different forces. Here is an updated fiddle so you can take a look at the idea. Update fiddle
I'm using angular nv-d3 and while making a chart, I'd like to have a specific point on the graph be highlighted.
My graph looks like:
I'm getting the data by consuming a rest response, my graphs will have 1 to 3 lines, and the each line is guaranteed to have the date point that I will be highlighting.
I could also live with just having a straight vertical line through that date, I just want a way to differentiate that specific date in the rest of the chart.
Couldn't find anything in the docs about this, and most of the methods I've found to do this use d3.select and jQuery, but I'm not sure if that will work with angular.
What I'm working with
I have data that I want to chart showing the intensity of rainfall over a period of time. The API documentation that I'm getting this data from says the following:
A very rough guide is that a value of 0 in./hr. corresponds to no precipitation, 0.002 in./hr. corresponds to very light precipitation, 0.017 in./hr. corresponds to light precipitation, 0.1 in./hr. corresponds to moderate precipitation, and 0.4 in./hr. corresponds to heavy precipitation.
Therefore, it seems logical to use a log scale for most of the data (otherwise everything less than moderate rain would be imperceptible), but this obviously causes a problem for when there is no rain predicted.
Possible Solution
The answer to this question suggested adding a small amount to the data and modifying the tooltip to match the original data.
Problem
This would work very nicely, but I don't know how to modify just the data that the tooltip of a Google Chart (the charting tool I'm using) references.
The Google Chart help documents here and here describe several possible roles columns from the chart's data table can play, and one of them is to be the HTML that is rendered in the tooltip. However, I was really hoping to not have to rewrite the HTML for that. Is there anyone here that knows an easy way to just modify the data shown in the tooltip?
The second link you provide gives you the easiest way to modify your tooltip content, Link. Just add another column like dataTable.addColumn({type: 'string', role: 'tooltip'});and then provide your own tooltip, like looping through all your rows and checking for zero values and replacing the tooltips where needed.
