How to add space in between the graph and the label(Apr 5)?
If you upgrade to the latest version (which is now 6.07) then you can use the xaxisLabelsOffsetx property.
Your chart will also look more "3D-ish" like the chart on the front page:

And here's the documentation entry for your property:

Thanks.
In your example, you're using the really old version 2.7.3 of Chart.js. With this version, it is probably not possible to do what you're looking for. You should first upgrade Chart.js (current latest version is 3.7.1).
In order to make the fewest changes to your code, I updated the version to 2.9.4 (latest available 2.n version) and simply added a second dataset with a lower weight than the base dataset.
Please take a look at your amended code here at CodeSandbox and see how it works.
I have a pretty basic radar chart and its working as it should.
Now I'm wondering if there is a way to add tooltips that use the default styling but for non-point coordinates, such as the centre position.
I would like to re-use the built in tooltips to benefit from styling and transitions without having to built a custom onHover overwrite.
So I would like to specify x and y coordinates in which the tooltip should show up and then the text that should be displayed. Some kind of callback would work I assume.
I suppose I could add a dataset which has all 0 values and add a custom tooltip to that, but that's not quite exactly what I am trying to achieve here.
Does Chart.js support this? I couldn't find it in the specs nor on stack overflow.
Thanks in advance!
I would like to show the location of vertical annotations in the stock chart scroller so that when the user zooms/pans away from the annotation, they are still aware of its location on the chart.
Unfortunately, the current version of the library 8.7.0 doesn't support annotations and markers in the stock scroller. It can show a series thumbnail only.
I'm using wpf with live charts library.
While I draw line chart, I want to add emphasis line on specific label.
It can be a important date with an event.
At first, I added another lineseries about the event. to use geometry
as a marker. But the geometry is somewhat small. Therefore some people couldn't find the event data.
So I want to add lines at tham. But I don't know how to.
Can someone help me?
In a video of the DevExpress Chart Demo (see attached image and link below) out on YouTube... the "Large DataSource" demo seems to have some sort of "range" bar at the top where you can see an overview of the data and adjust the left and right of the range and drag the range left and right as well. In the current version of DevExpress the demo doesn't have this feature. Does anyone know how to implement it... or at least what it is officially called so I can look it up in the documentation.
Also, if anybody knows, is there is source code for this demo?
The actual video I'm talking about is here: https://www.youtube.com/watch?v=HmA6vANrKKk

Your screenshot is demonstrates the RangeControl, which provides a data range selection functionality.
ChartControl on your screenshot is bound to the RangeControl via the RangeControl.Client property.
