I am trying to use the performance tip which stated that calling the Add() method lots of times is frowned upon and using AddRange() is the better option but I can't seem to add a range of values because I am using a PointCollection
What I was trying to do is draw a line series which involves plotting chartValues. I cant use ChartValues<PointCollection> because LiveCharts doesn't know how to plot the Point datatype
So I read that you specify what X and Y should be through the use of the mapper. It requires a type so I could put Mappers.Xy<Point>() etc

@ImmutableGlitch
So I am trying to produce a chart that plots 2 values instead of treating X as an index. I have setup the mapper so that it recognises how a Point should be plotted. I have a PointCollection of my data without the use of a ChartValues object, so can somebody advise me on how to plot the data?
I have SeriesCollection(mapper) but i'm not sure how to then link the data I have to the series collection.
Thanks for any help!

Hello, I'm using the basic chart example and wonder how I can set fixed axis ranges. Right now the axis range dynamically adjusts with the range of visible values. I thought putting zoom to "none" in the CartesianChart would solve the problem but it doesn't
Mrxx99
@Mrxx99
@dewell81 An Axis has properties for min and max values which you can use for this
dewell81
@dewell81
thank you! damn, i tried maxrange and forgot to check min/maxvalue as well

@kbhaden In WPF controls of installed nuget packages are not added automatically to the toolbox, but you can do that yourself (look here for example: https://www.dreamincode.net/forums/topic/319756-add-new-wpf-controls-from-nuget-to-toolbox/). But most people don't use the toolbox at all for WPF development. You normally just add the xmlns to add the namespace and then add the controls in xaml

@dewell81
now that I have the chance .. I have one tiny issue with the chart. When I start my wpf application I create the SeriesCollectionX and Y in the constructor of my viewmodel but although I change the properties that are bound to the chart I have to switch the tab forth and back before the chart is actually visible on the screen ..
its inside a tabcontrol, when i switch the tabcontrol forth and back it works perfectly

Hi guys, Does anyone know if it's possible to extend the AngularGauge so I can draw a border around the outer edge? (like you can using Stroke for the normal gauge)
@dewell81 are you calling NotifyPropertyChanged when you update the properties? And is your binding mode set to OneWay or OneTime. Those are the two most obvious problems, without seeing some code.

Hi everyone, is there anyone here who bought a LiveCharts.Geared license? We would like to buy a LiveCharts.Geared license for our company. However, we need an offer or at least an invoice. Do you get an invoice after the purchase? Unfortunately the developer @beto-rodriguez does not reply to emails about this.

Hello guys, anyone can point me in the right direction how can I refresh (invalidate?) the chart without having to modify the data behind it?

@freamdev Did you try InvalidateVisual()?

Hello! Is it possible to have OlhcSeries superimposed to RowSeries instead of ColumnSeries?
Richard Pinter
@freamdev
@pinki Yes I did, tried it on both the chart itself, the window and the axissection itself that I want to add to the chart in runtime. In either way the axis section only gets drawed once the chart values changed.

Hi, is anyone there ?
Michael Heinrich
@pinki
@freamdev Then try the Update(bool restartView, bool force) method.
Richard Pinter
@freamdev
@pinki The Update method seems to work, thank you!

Hi all, I am trying to use the LogarithmicAxis and even though I set a MinValue, Min Range to 0.01 it goes lower than this value and show me an area in the axis that has no points in it (first point is higher than 0.01), any idea ?

</wpf:PieChart>).

@kimseung
@voitje May be..... I think.... -> -> <lvc:PieChart.AxisX >
<lvc:Axis Labels="{Binding Labels}" FontSize="20" Foreground="Black">
<lvc:Axis.Separator>
<lvc:Separator Step="1" ></lvc:Separator>
</lvc:Axis.Separator>
</lvc:Axis>

Hi, is there any function that enables user to auto-scale the amount of points plotted. For example, decreases the amount of points plotted as i zoom out, and increase the amount of points plotted as i zoom in.
