Good day!
I need to determine the value of the visible graph y from the x value and the problem is that I can’t calculate the y value outside of the data I’m rendering
example data:
[
{ x:1, y: 10 },
{ x:5, y: -5 },
{ x: 9, y: 15}
]
I use SCISplineMountainRenderableSeries and I need to show the intersection of the graph at point 3.5
I need a point but I have only one coordinate value
how can i get this y value?

Is the styleFor function of SCIPaletteProvider that was in Version 2.0 not implemented in Version 4.8?
Also, are there any plans to implement it?
I am upgrading from SciCharts 2.0.1 to SciCharts 4.3.
When the color was set using SCI Palatt Provider in Version 2.0, the memory used was 200M, but in Version 4.3, the memory used may consume as much as 1G.
I tried to devise it by setting the Sampleing Mode, but it is not very effective.
SCI Charts is used to display the spectrum data of audio data while playing the sound.

I am trying to zoom and pan the line graph in my macOS app the zoom is working but I am not able to pan through the zoomed graph its not at all scrolling and also I wanted to know how can I add click event on the graph so that I can display some more data on click at a particular coordinate apart from tooth. I have shared my view controller. I will really appreciate any help as I have spend a lot of time figure this out and have no clue where to go from here.

Hi,
We found that the part of our project that uses scichart does not work correctly on iOS12, and then we tried to open a browser on iOS12 to the scichart javascript demo webpage, and found that it did not work.
What is the minimum iOS version supported by javscript scichart?

The wick for the up candlestick go through the body while the down candlestick do not. How can I make the wick inside the body part disappear? I didn’t change any settings of stroke and fill style. Thanks.
let candlestickSeries = SCIFastCandlestickRenderableSeries()
candlestickSeries.dataSeries = dataSeries
candlestickSeries.yAxisId = "right"

Hi, I’m looking for a way to programmatically dismiss a RolloverModifier from a chart. I’ve been tasked with creating a user experience that does two things: 1. when a user stops scrubbing on the chart, the rollover modifier should persist, and 2. when the user taps outside of the chart the rollover modifier should disappear.
I’ve accomplished the first part of the problem by implementing a subclass of SCIRolloverModifier and overriding the onEvent(args:) function, but I cannot figure out how to dismiss the rollover modifier when the user taps outside the chart surface.
Is there a way to accomplish this?

I’m developing chart with sci chart. And I current make candle stick chart.
I want to get correct center coordinate from user’s touch location.
so, I tried this way.
- get touch location
- get axis data from touch location like this
- get coordinate from data
let location = gestureRecognizer.location(in: self) // type is CGPoint
let selectedDate = xAxis.getDataValue(Float(location.x)) // xAxis's type is ISCIAxis
let selectedPoint = xAxis.getCoordinate(selectedData)
If I do that, no matter how far to the right you touch from the center line of the candlestick, you will get the position of the left candlestick.
If the candlestick center line is not crossed, the left data is unconditionally obtained.
I want to get the data closest to the touch, how do I do that?

Please answer about it (https://www.scichart.com/questions/ios/is-it-possible-to-make-customannotation-like-axis-marker-annotation)

My purpose is SCIAxisLabelAnnotation draw above on border line.
like this <– this is just design guide. not a app screenshot.
But SCIAxisLabelAnnotation is can’t overlap renderable series area. So It can’t overlap renderable series area border line.
So I have to customize.
I think that If I add view into render surface, and it’s order make to zero, I can get TOBE result.
My code is below.
Code
But SeparatorView is always on view’s top. So I’m struggling.
You can See result.
It’s covered all surface.
How can I insert some view below Y Axis or SCIAxisLabelAnnotation?
tl;dr I want customize annotation shape and it draw above on 1st top layer.

Hello,
I have a problem reading the position of the vertical line annotations. The function “getX1” returns type double (0 – 1) or date depending on whether the annotation has not changed its position. I found out from the documentation that the type returned depends on the coordinateMode. I set it to absolute. This change had no effect, unlike in library written in Java. Is it possible to set the default type? Can I ask for any guidance needed to solve the problem? The version of the library I am using is 4.4.2.5871.
Thanks in advance!
