Is there any way to make Series Point Geometries clip through the graph boundaries?
When I have any points with GeometrySize > 0 they expand the graph boundaries and mis-align all the axes separators

Setting a negative Margin doesn't seem to help

Hi there, do these chart controls work on .NET 5?
Daniel Mittelstadt
@DMtsdt
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?

Hi there, do these chart controls work on .NET 5?

Apparently not exactly. I'm using it in a .Net Core 3.0 project and it's pulling in .NETFramework 4.7. Bummer, but this appears to be abandonware at the moment. Hopefully it will get updated to support .Net Core or .Net 5.

Hello, I'm using the line chart. The number of x-axis is 123, so how can I increase it further?

I need help guys, is anyone here? :(
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」∠)

Hello, thank you for always helping me. Can I use the zoom function without the mouse wheel?
heinsea
@heinsea
maybe you can control the X Axis just like this if you use the CartesianChart , you can set the Attributes MinValue and the MaxValue of the XAxis then control the zoom of chart
private void ZoomIn(object sender, RoutedEventArgs e)
{
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)
}
}
};

getting an error message when using "ChartValues = new ChartValues<CorrectSquaresModel>();" The error is "using the generic type 'ChartValues<T>' requires 1 type arguments". Very much a beginner. I have in my code the following
Daniel Mittelstadt
@DMtsdt
@spaseur04 seems like you're trying to define a variable, try
var chartValues = new ChartValues<CorrectSquaresModel>();
then you can set chartValues in your series:
YourSeries.Values = chartValues;

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'.

LiveCharts is a great product. Had a few questions so I emailed you @ your support email. Please check. Thanks so much!
@ChrisRFLogic_gitlab It works for me just now.

I believe it's abandoned, as well as support for this project

I just purchased the geared library about a week ago. Emailed support a few questions on the 13th. No reply what so ever yet.

@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);

@swraza
Great thanks @KiwiLostInMelb I will check and will let you know. Moreover, can you also guide me how can I select multiple points from chart using mouse? using drag drop/lasso etc?

Hello, does anyone know if the email Support@lvcharts.net is active? Nobody replies to my email
miket83706
@miket83706
@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.

@miket83706 I have a problem with activation too, i don't now what i should do, because i bought license and livecharts hasn't received me acrivation code yet.
miket83706
@miket83706
@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.
