Never mind, I changed the series from scatter to line and set the stroke and fill to transparent and the labels are shown above now.

Hello,
Simple question, does the charts implements the Dispose() method?
In case of cycling loading of charts the RAM consumption grows like nothing was cleaned from the previous run.
If not, is there a proper way in this library to ensure resources are free after we don't need them anymore? (without closing the windows, simply destroing the chart and make a new one)
Many thanks,
JiGlain

Do someone know how to change the number of shown decimals on an axex?

The Axis class has a property called "LabelFormatter", is that what you need?

Hi everyone!
I need to hide the grid of a cartesiac chart. How I can do it? I want to do it in winforms (VB.NET).

Thanks

I think the property IsEnabled of the class Separator can help you, for example:
axis.Separator = New Wpf.Separator() With {.IsEnabled = False}

Hi guy, is this forum still valid? I need some help too. I'm using Cartesian chart on WinForms but I can't get the percentage to be displayed on the tooltip, I tried creating my own formater and setting on the property LabelPoint, but the thing is the ChratPoint.Participation is always = 0.00.
What can I do to get this value?

PS: With PieChart it works perfectly

Hi guys. I cannot get the stuff like cartesianChart at the toolbox (VS 2019) even after re-building the app. Any ideas?

Do someone know how to change the number of shown decimals on an axex?

Hi. I would suggest to cut them before adding to the series' values variable, maybe using Math.Round(type variable, int num).

Hi guys. I have about 20 LineSeries with changing values every 1ms, first i build the chart with the "normal livechart" but now i want to build it with Geared cause of the high performance. I dont got the same output with the geared. the only thing i saw to change is the LineSeries to GLineSeries or do i forgot something?
thanks

Hello Everyone

I ordered Geared WPF license and activated successfully.
But I cant't sign in admin web site.(I can't invite team members...)

https://lvcharts.net/licensing/manage

It says "This site uses external providers to authenticate your account, please use any of the following providers." .
I'm stuck in an endlessloop when sign-in in Microsoft account.

Windows10(I tried on chrome, fire fox, and edge)

Is there anyone know how to solve it?

Thanks

Hi all. I’m trying to use LiveCharts on UWP application (Just <add LiveCharting:CartesianChart /> in XAML),
But when application start, it crash on « InitializeComponent » …. Is the UWP is fully functionnal ? What's the problem ?

OK : problem come from nugets package -> I installed the 2 packages LiveCharts and LiveCharts.Uwp ... After LiveCharts package suppression, that works great !

Wonder if anyone has attempted to share the size between two Cartisian Graphs? Found the stackoverflow post below but not quite what I am looking for...

https://stackoverflow.com/questions/46877065/align-two-cartisian-charts-with-different-axis-label-width

Mattew
@matsydoodles_gitlab

Dug through the code last night and looks like the Axis Width are never used by the LiveCharts, well the set value is never taken into consideration. I assume you are able to set it because it inherits from the FrameworkElement. It then blindly just auto sizes to biggest content length.

I introduced Width on to the AxisCore.cs and hooked it up to the FrameworkElement value, then in ChartCore.cs in CalculateComponentsAndMargin where it calculates the biggest, I added an override that if axis.Width is not NaN (auto) then override biggest Width with the set value.

Seems to work, probably some edge cases. Not sure if I'll bother with a PR as it is probably a bit hacky and realistically the project is dead by the looks of it.

If you use the library and feel like supporting the guy who created it then why not?

Hello, we are testing if LiveCharts will be viable for our WPF project. So far I have tried basic version which was very slow, but after using geared package it seems to be running quite well. However I dont understand the licensing. I have downloaded Geared from Nuget, so I think I am in trial period now (altough I didn't specify any account anywhere and dont see any licensing info via nuget or anywhere). There are many developers working on this solution, we have tried now to build it on another PC and it seems fine. I am woking on the UI part so I want to buy the licence for Geared package. But how will this affect other developers? Will they be able to build the project without the licence afterwards? Or do we all need a licence? And is there a way to see my actual license status and to which account is it bound (I have visual studio for a different account than my windows account). Many thanks for any info!

I have the same question, don't know how to apply the license to our WPF program.

Hi, when using the MVVM approach in wpf, two linecharts cannot have the same View Model instance as DataContext. What happens is that the line in the first graph goes invisible and is only visible in the second chart. Is this a bug?

Hey everyone, I was looking at this library a couple years ago as a potential replacement for ZedGraph. My job moved away from programming and I haven't had a need for a graphing library since then. I happened to come back and look at the status on the library and it looks like development stopped. Does anyone know what happened?
