I believe my issue is caused by the fix for #341
Is there any way to disable this so the points DO clip if they're on the edge of a chart?

Is there any example of this with for loops? or foreach
where you have to addvalues with index
Hello. I want to fix X Axis separators in a constant changes graph I made for an oscilloscope like display. Currently it wiggles a lot :( Any tips on how to do this?
I am fixing my X Axis limits to always show 1000 milliseconds. I want the separators to not move from update to update, but to instead update their labels. I cannot guarantee that the number of points on the graph will always be constant.

I figured it out - my constant changes values were being updated by event notification, which could happen with unequal time spacing. On my axis update if I just do some additional processing to make sure the maximum X axis time is evenly divisible by the separator time, then my separators remain at fixed draw positions in my chart. Thanks for having this channel here to rubber ducky off of.
Can I export it as PNG without displaying the chart control? I have lots of data to sampling using Task class for less time, then render them on the chart in a window and export it as PNG. it can be done well. But I don't know how to achieve it if I don't display the window (my boss want it, so sad). I am not familiar with The Thread process and UI Thread, how to handle all these thing and avoid thread conflicts if exist Task ? When the PNG to be exported that is also a big question for me.... so hard.... (:з」∠)
private void ZoomIn(object sender, RoutedEventArgs e)
{
if (ZoomLevel < ZoomLevel_Max)
{
HalfPointsCountPerZoom = (TimeAxis.MaxValue - TimeAxis.MinValue) / 4;
{
if (ZoomLevel < ZoomLevel_Max)
{
HalfPointsCountPerZoom = (TimeAxis.MaxValue - TimeAxis.MinValue) / 4;
TimeAxis.MinValue += HalfPointsCountPerZoom;
TimeAxis.MaxValue -= HalfPointsCountPerZoom;
if (TimeAxis.MinValue < 0)
{
TimeAxis.MinValue = 0;
}
if (TimeAxis.MaxValue > TimeAxis_TotalPointsCount)
{
TimeAxis.MaxValue = TimeAxis_TotalPointsCount;
}
ZoomLevel++;
}
} 
This is the code from the example. How to add candles in a loop? I have a file with OHLC. How do I add them all to the chart?
cartesianChart1.Series = new SeriesCollection
{
new CandleSeries
{
Values = new ChartValues<OhlcPoint>
{
new OhlcPoint(32, 35, 30, 32),
new OhlcPoint(33, 38, 31, 37),
new OhlcPoint(35, 42, 30, 40),
new OhlcPoint(37, 40, 35, 38),
new OhlcPoint(35, 38, 32, 33)
}
}
};
cartesianChart1.Series = new SeriesCollection
{
new CandleSeries
{
Values = new ChartValues<OhlcPoint>
{
new OhlcPoint(32, 35, 30, 32),
new OhlcPoint(33, 38, 31, 37),
new OhlcPoint(35, 42, 30, 40),
new OhlcPoint(37, 40, 35, 38),
new OhlcPoint(35, 38, 32, 33)
}
}
};
then you can set
chartValues in your series:YourSeries.Values = chartValues;
I need your help to achieve 1) being able to select multiple data points using drag/drop or Lasso tool on the chart
2) show right click context menu on the chart
Hello, thank you always. Is it possible to display only the data I want to display in the data tool tip?
this page not longer working?
Hello, somebody use geared with NET 5.0 ? In Nuget you can not find version for NET 5.0. I have tried with Version 1.2.9. it works but there is Warning "Package 'LiveCharts.Geared 1.2.9' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework 'net5.0-windows7.0'. This package may not be fully compatible with your project.
@ChrisRFLogic_gitlab It works for me just now.
@wajahat > Hello there, AddRange() method not working for ChartValues<ObservablePoint> any help? @Wajahat
I use add observable point similar to the following..... private ObservablePoint[] _PowerHP = new ObservablePoint[ListSize];
_PowerHP[Index] =
new ObservablePoint(
XAxisValue,
Math.Round(Convert.ToDouble(row["PowerHPFiltered"]), 1)
);
Series_PowerHP_Base.Values.AddRange(_PowerHP);
@bsiedmiogrodzki_gitlab See my comment above. I still have not received any reply to my email. So NO SUPPORT. This is false advertising since the website said you get additional support and I have not received any additional support what so ever. If I would have know it was a dead product I would have not purchased the "geared" version with the additional support.

@bsiedmiogrodzki_gitlab For some reason my activation worked. I bought the geared version about 10-14 days ago. NO SUPPORT from live-charts. I would wait a couple days and then if still no response from support, I would contact your credit card company and try to get a refund. That's what I am going to do since I am not getting any support.
this isnt working
