Has anyone had problems with switching between different chart types on the Cartesian chart?
The first time I use a HeatSeries chart everything works fine. If I then clear the chart (chart.Series.Clear();) and for example create a LineSeries chart, the Heat Series legend is still displayed:

Also I'm getting weired values at the Y axis when changing chart type to OHLC diagram:

Does someone have tips what could I do to handle that kind of errors?

Hello. New to Live-Charts. I wanted to know if it is possible to Fill a series with a custom color gradient? I am trying to recreate the CIE XYZ color chart using Live-Charts and can't figure out how to fill the area with the various RGB colors. Any help would be appreciated. Thanks!

hello i have a RowSeries, you can change the color of each value depending on a condition, i tried this but it only changes the last color:

        var mapper = new CartesianMapper<double>()
            .X((value, index) => value) //use the value as X
            .Y((value, index) => index) //use the index as Y
            .Fill(value => value < 40 ? new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromRgb(124,252,0)) : null)
            .Fill(value => value >= 10 ? new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromRgb(255, 255, 0)) : null)
           .Fill(value => value >= 20 ? new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromRgb(255, 128, 0)) : null);

Hi All,
I was wondering whether we can have fixed colors instead of dynamically resizing color space on Heatmap

For example, 5 is always red no matter what the lower and upper bounds are

Yesterday I've installed LiveCharts.Geared, but after installing completed, the Toolbox of Visual studio 2019 (16.4.5) cannot find any control about LiveCharts.

When I use a axis separator I get a strange behavior...

<lvc:Axis MinValue="-20.32" MaxValue="20.32" Title="X [inch]" 
    LabelFormatter="{Binding FormatTo1Decimal}">
          <lvc:Axis.Separator>
               <lvc:Separator Step="2.54"/>
           </lvc:Axis.Separator>
 </lvc:Axis>

I would have thought the initial value for the iteration in the LabelFormatter would have been one on the limit either Min or Max and it seems to be, but when I debug the first value is -20. I'm losing the decimal part of it.

Any idea?

Hi All!
I have sent an email more than two weeks ago to Support@LvCharts.net about the community license of the Geared library but no answer yet. Could somebody help me about this, how to get this license?

Hi!
Secondly, I have the following class

    public class Point
    {
        public double PVUpper { get; set; }

        public double PVLower { get; set; }

        public long Time { get; set; }
        }

I would like to plot an array of this class on a line chart where the axis X is the Time value and I would have two legends on the axis Y with PVUpper and PVLower. Is there any similar exmaple for this?

Hi, everybody. I'm creating a simple bar chart. At the touch of a button, it creates a statick of a word( how many times a letter occurs in a word. The problem is that when I want to create statistics for a new word, I don't correctly re-create column captions. Has anyone ever met such a person?

var data = Ngramm.NGrams(textBox1.Text);
var chartvalues = new ChartValues<int>();
foreach (var k in data.Keys)
{
chartvalues.Add(data[k]);
}
if (SeriesCollection.Count > 0)
SeriesCollection.Remove(SeriesCollection[0]);
SeriesCollection.Add(new ColumnSeries
{
Title = textBox1.Text,
Values = chartvalues
}
);

        Labels = data.Keys.ToArray();
        Formatter = value => value.ToString("N");
        DataContext = this;

Hi all, I have tried plotting 10,000 observable points on a LineSeries chart in WinForms and my program freezes up. I understood Live-Charts could take up to 100,000 easily. Have I done something wrong?

Hello everyone, I have a question. I am working with the GeoMap class in a winforms project, the problem I have is that I don't know how to access the MapData that I have. I know that when I run the landClick method, it returns the MapData that I have selected in the map, but how can I access all of them without executing said method? Thanks in advance.

Hi Everybody. I have a problem. I wanna show 3-4 types temperature in Cartesian Chart. My values will come from PLC. But I don't know how can I add in chart. Plc values are coming correctly. I'm changing them as variable. Or you can think you are adding a variable by using textBox and you wanna show them in Cartesian Chart. Please Help Meeee :)

tm1k

@tm1k

You would need to wait for the Event when data arrives from the PLC and build a chartvalue with the new data

Hello guys, I need your help. I use a CartesianChart and a couple of LineSeries. Each Series is always 10 entries long (X-axis) and holds times in seconds (Y-axis). What I cant figure out is: 1. How do I make all 9 vertical seperators visible at all times (default seems to be dependant on the control's size) 2. I need my Y axis not go below 0 since a negative time does not make any sense, so how can I limit that? Axis labeling displays values as expected.
Any help is greatly appreciated (C#, WPF)

recounter7

@recounter7

@boatschl : 1. cartesianChart.AxisX[0].Separator = new LiveCharts.Wpf.Separator { Step = 1, IsEnabled = true, StrokeThickness = 1 }; 2. cartesianChart.AxisY[0].MinValue = 0;

Good morning ! I am struggling with using lvchart in a MVVM style. I am trying to implement a command that would allow me to get the pixel coordinates of all the points from a LineSeries. I am using this example https://lvcharts.net/App/examples/v1/wpf/Events, but I would like to have an equivalent of the "ConvertToPixels" method that is used in the "ChartOnDataClick" event. When clicking one of the graph's point, I can get the pixels value of a given ChartPoint p (p.ChartLocation), but I would like to have all the pixels coordinates of all the plotted points, not only the one I clicked on, hence my wish to use something like Chart.ConvertToPixels. I am new to WPF, so I don't know if I am missing something obvious, or if this is more complicated ?

Hey hope you all are doing well! I am trying to make a graph that will visualize for the user a certain spec that was drawn for them. I am able to read in all my data points but have hit a bit of a wall on drawing a rectangle around specific points. One method that I have been trying is using sections, I have had some minor success in that I can get either the height or width correct but I can't limit the size of the other length and it goes to infinity. Is anyone is aware of a method of truncating a section so that it doesn't run all the way from zero to infinity? If anyone has suggestions for other methods as well I'd appreciate it. Thanks
