Unable to create custom indicator

Checked all the samples in here: https://www.anychart.com/products/anystock/gallery/Stock_Technical_Indicators/?theme=darkEarth All are calculated by any chart functions. indicatorPlot is getting members like .adl etc..
Also checked the sample here with setCalculationFunction: https://www.anychart.com/blog/2018/03/14/custom-technical-indicators-javascript-stock-charts/
Is there a way to "map indicatorPlot" with a csv values like drawing the main graph? Or is datatable can store indicator values to show underneath the chart like oscilators.
The main question is: Is there a way to display a custom oscillator under the chart feeded with values from csv, json etc.. ?

Yes, in this case, the indicator is a usual series that is based on your data. Simply create a series from your data, provide the desired name and that's it.

ChartJS re-rendering bug

So I'm building a trading tool and am using chartJS for the charts. This is how my charts look now on the page:
So my problem is that when I change the time period of the chart, the chart shows randomly the old data mixed with the new one.
You can see the behaviour here: https://gifyu.com/image/vda5
For now I can't use the Big chart together with the small one on the same page because the big chart which has the timing period has also multiple AJAX calls so every time I click on "1W" for example, a new call is being made and the chart is drawn over.
Things I tried:
I know that for dynamic charts in chartJS I have to destroy the chart, so I'm using
if (window.chart !== undefined) window.chart.destroy();
and for the small charts I use an empty array and push the elements inside. Here is how I do it:
if ($(quoteDisplayEl).hasClass('quoteDisplay-light')) {
chartHandel.push(quoteChart);
} else {
window.chart = quoteChart;
}
so for the big chart I assign it to a global variable and the small one I push it to the empty array - that allows me to have multiple charts on one page.
But in order for the big chart to be destroyed I should destroy and re-render all charts from scratch (I guess) and I tried multiple was of achieving that with now luck.
Unfortunately the code is over 500 lines and has lots of variable data coming from APIs and DB thus I can't make a fiddle demo.

I prefer chart.update() over chart.destroy().
Here's a small, simple example how I usually update data.
I make one object per chart with labels (empty array) and data (empty array) and colors and all the stuff you need.
I fill these arrays with data I get (AJAX).
Optional: If I get all the data and need to filter it to show less data, I copy my object to keep all the data I got and have all the data I need now for my chart in another object
Make an updateChart() function which alters your displayed data or saved data from your backup object or use new data from a new AJAX request.
End your updateChart() with chart.update() (or whatever your chart is called).
Multiple charts shouldn't be a problem and you shouldn't have to destroy your chart.

D3 - Best way to format data for multi-series column chart

I have 8 categories of data per facility and have created an interface to compare multiple facilities against each other for 'scoring'. The categories are not related to each other in any sort of fashion. The last element to add is a graph with the facility scores graphed against the other selected facilities. When looking at the examples online, most data is in a CSV format but I will be swapping out values triggered by a drop-down list.
Example of data...
facility_score = {
"a":20,
"b":30,
"c":1,
"d":55, ...
}
I have a finished "single" facility done and want to expand upon it.

D3 graphing selective portions of data set

I have a large time series data set I need to graph, and am trying to use D3 to do it. I plan to have my graph have the x-axis be time, and allow for movement of the graph in the x direction. I want to have the graph only load/display the points that exist in the current time range on the screen.
For example, if my dataset has times 1-100, but the graph starts out with times 1-10 shown, the graph should only graph points 1-10. Then the user may move to the right and see times 5-15 and the graph should update accordingly.
Can anyone explain to me how this might be done via d3? I am having a hard time bridging the understanding from an entire data set being loaded in at once and graphed immediately to selective graphing of subsets of the data.

I think you are looking for the selection.filter() function. For example you can have:
var allNodes = vis.selectAll("Nodes").data(data.nodes);
var validNodes = allNodes.filter(function(d){return (d.time>1 && d.time <10)});
//use normal graph functions on validNodes.
You can also apply filter directly on the array of nodes.

Stacked Bar And Scatter Alignment

I have a chart here: http://jsfiddle.net/wergeld/bx82z/
What I need is for the stacked bars and the scatter points to line up on each other based on the data X-element (county name in this case).
Getting the bars to stack was simple. But as you can see in the example the scatter points show up in the middle of the chart - not on the same x-value as the others.
I suppose I could create a category list (using the county names) but there may be cases where I do not have all 3 data elements for all counties - how to handle that scenario?
I did great the category axis and it is still doing the same thing: http://jsfiddle.net/wergeld/YckwW/

You were not defining the series correctly to achieve what you were wanting. See updated jsfiddle for what I think you are looking for.
In the cases where you are missing a piece of data for one of the countries you could always use null, which simply means there is nothing to display for that data point. See Missing Data Sample for an example. It is case sensitive so make sure that null is all lower case.
