QUESTION
I'm using apex charts to create a graph of real-time data coming in from the back-end.
I have used the demo as a guide and implemented my own real-time chart (https://apexcharts.com/vue-chart-demos/line-charts/realtime/)
I want the data to scroll like in the linked example, currently, mine appears to redraw the line each time it's updated (https://imgur.com/a/1aTc1JV)
I use this function to update the series data with a fixed-length queue which is updated every second (queue.append(newData) and then queue.pop(0))
...ANSWER
Answered 2022-Feb-10 at 14:43Insted of doing queue.pop(0)
set range
in xaxis
to length - 1 of your initial data (if type: "numeric"
).

QUESTION
I saw that in the .NET version of LightningChart that there is a way to add breaks in line charts. Is this possible in the JS version as well? I saw someone ask a similar question a couple years ago, but hoping that this has been implemented since then.
I've looked through the documentation and examples and didn't couldn't find anything. I'm hoping to replicate something that looks like this in ApexCharts: https://apexcharts.com/javascript-chart-demos/line-charts/null-values/
...ANSWER
Answered 2022-Feb-01 at 06:11Line breaks in LineSeries
can be specified by using NaN
.
At this time there is no official mention of supporting this, but this is just about to be changed with the next version release. Afterwards, please check the data input method documentation of each series type whether this is supported or not because it might be that not all features support it.
Here is a snippet with the same data as in your referenced ApexCharts example.
QUESTION
Is there a way to make an XY lightning chart move its xAxis at a set interval?
Scenario: I currently have an XY chart that's tied to a process that emits data every second. The chart updates correctly, but the xAxis moves over very quickly and then pauses until the next event. I'm hoping to make this more of a smooth process between each second interval.
I've worked with Apex charts in the past and here's an example that shows the xAxis gradually being added: https://apexcharts.com/javascript-chart-demos/line-charts/realtime/
Is there a way to make lightningcharts act in this same manner?
...ANSWER
Answered 2022-Jan-25 at 09:06By default the axis scrolling is either instantaneous or animated (in rather snappy manner). The animation speed is not customizable.
If you want to replicate this scrolling behavior then you would have to 1) disable automatic scrolling and 2) animate each step of the axis scrolling manually.
Automatic scrolling is disabled with Axis.setScrollStrategy
Axis interval can be set with Axis.setInterval
Below is a code snippet which you can run right here in your browser to see how it looks and also reference in your own application.

UPDATE (11/19/21): Added Additional Solutions
Most of you probably don't remember me from my previous question, Circles not updating correctly for multiline charts with two-level nested data. I managed to figure out/work around my issue there (although I still am not convinced that what I came up with is 100% correct); however, I now have another question.
My y-axis data (d.mval) has extreme outlier values. As a result, my charts get compressed, with quite a bit of blank space. See, for example, the "Cash Flow" chart in this JSFiddle: https://jsfiddle.net/etonblue/a98m52k4/3/. I've tried various combinations of median, mean, average, std dev, etc., to try to set the domains, but haven't yet found a solution that works consistently for all of my data. So I've resorted to hard-coding my domains:
...ANSWER
Answered 2021-Nov-12 at 13:49The code you provided isn't too relevant to the solution. Working from your fiddle, the solution is in your callbacks for the y positions of your line and circles. For your line:

QUESTION
I'm currently using Apexcharts to display a data series. In one of the options, I can select an array of colors as defined in the documentation, which is an array of strings. Obviously, passing in hex strings works just fine.
However, what I'm trying to do now is to have my data series on my graph show with patterns. I understand that I can use the fill
object as defined here, but that would define a pattern for the whole graph, whereas I would like to define it for certain data only.
Since the color
array is an array of strings, is there a way where I can define something like linear-gradient
or something equivalent but in string format?
EDIT:
As an example, suppose I have this data series from the Apexchart website. Is there a way that I can set a condition, say if the person is 'Joe' and the type is 'test', then set the gradient to be something (for example gradient: slantedLines
)?
The result would therefore be something like:
EDIT2:
I have also seen another question whereby we can specify the property fillColor
to specify the color of a given bar in this post. Is there an equivalent to explicitly set the gradient?
