Drop data from HighLowSeries
I have a requirement to drop old data from a HighLowSeries manually every 30 minutes or so. Currently i've implemented this as follows: - copy the highlowseriespoints to a temporary list. (highlow.Points.ToList().GetRange(0, highlow.PointCount)) - remove old highlowseriespoints from temporary list. ...

Re: Update to version 10
Lasse, It doesn't seem to be related to serialization. I've attached a VS project showing the issue. This creates a new empty chart in code and adds a single annotation. After creating the chart it opens a properties editor. Using the properties editor go to ViewXY -> Annotations -> Annotation[0] ->...

Update to version 10
All, We've updated our Lightningchart from version 8.1 to 10. I had to make a couple of changes because of the updated API. All seems to be working fine again.....however it seems like something changed in the font rendering. We're using Arial font size 8.25 for our axis labels and in the old versio...

StockSeriesData
I have a requirement to display OHLC data every minute. When creating StockSeriesData I can only specify the Date. Is it possible to display multiple StockSeriesData points per day?

SeriesEventMarker performance
We're having issues with chart performance when there are a lot of serieseventmarkers (between 10 and 15 thousand) Our chart displays stock prices and creates a marker when a large trade is detected. These markers are displayed as circles and the radius of the circle depends on the size of the trade...

Re: Add line to linecollection
I really need the linecollection since i'm adding a lot of lines (bars of 1 pixel) and was told this was probably the most efficient way to do this. The question is: Can I add a new SegmentLine to an existing linecollection? The linecollection works perfect in a static chart but I have a new require...

Add line to linecollection
I want to use a linecollection in a realtime chart so I need to add lines when data comes in.
All other series have functionality to do that (AddPoints, AddValues etc.) but I cannot find anything for linecollections....
What should I use?

AnnotationXY transparent fill
I have a requirement to display some text on top of a chart and tried using the AnnotationXY object with a transparent fill color.
Turns out the alpha is ignored when the AnnotationXY is painted. Any idea for a workaround to implement this requirement?

PopFromZoomStack crash
When setting the RightToLeftZoomAction in the ZoomPanOptions for ViewXY to PopFromZoomStack my program crashes when zooming in or out. The call stack is below. I can reproduce the problem very easy by just adding a new chart to a form. Adding two default axis (X&Y) and set the RightToLeftZoomAct...
