@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);

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.

                cartesianChart1.DataTooltip.SelectionMode = LiveCharts.TooltipSelectionMode.OnlySender;
this isnt working
can someone help please? Since all creators of this project wont answer :(
this wont work in winforms
Error CS1061 'UserControl' does not contain a definition for 'SelectionMode' and no accessible extension method 'SelectionMode' accepting a first argument of type 'UserControl' could be found (are you missing a using directive or an assembly reference?)

Hello, is it possible in winforms, when I put 50points into chart, I want after .Add that it automatically be zoomed in and show only 10 last points?
KiwiLostInMelb
@KiwiLostInMelb
@StevenSagull yes. You can populate the series and set the XAxis.SetRange(start, end) to zoom to the data you want.

Nice, solved.

Hi, my y-Axis shows the values "0.1", "0.2", "0.30000000000000002" and "0.4". How can I avoid this double error in the axis? I can not format the axis, because I never know what values are coming and how many decimale places are best for the plot

Can I shift values a bit to left on chart? I have candlestick and line series, and I want to center points of line series at the left side of each candlestick, not in middle as is now

Hello, I want to use Live chart as a 2D coordinate system.
Mean that origin point is at (0, 0) and other point around origin point.
How can I draw a X=0 and Y=0 line to enhance the relationship between points with origin point?

Hello Everyone. I am trying to differentiate the scatter series by certain data attribute and doing this right now
new ScatterSeries
{
Title = "Series C",
Values = new ChartValues<ObservablePoint>(),
PointGeometry = DefaultGeometries.Triangle,
StrokeThickness = 2,
Fill = Brushes.Transparent
}
But the problem is that "DefaultGeometries.Triangle" only supports 4 different symbols what if I have more than 4?

Hello Everyone! I'm currently doing a simple joystick viewer application using WindowsForms and I would like to do a chart to show the joystick movement. for example a dot or a cross that starts in the center (0,0) and as I move the joystick the dot (or cross) would move with it.
now I have all the code to normalize my area and move the dot
I just need a direction as to what type of chart and how to set the chart up
a very similar situation as that of @kerol2r20
Daniel Mittelstadt
@DMtsdt
@Articrox Basic Line Chart should do the trick
You can set up secondary axes with differently styled dividers at 0,0 as a "crosshair"
If you mean to do a point that simply tracks the joystick movement a simple ObservablePoint should do
Set the LineSeries fill to transparent and LineSmoothness= 0

Hello, I'm trying to create some vertical bar charts with high and low watermark lines (min-max), the idea being that the columns should all be within min/max values. I haven't been able to find where to create such - is it just a case of adding the min/max values as an extra seriescollection?

I am trying to create a vertical bar chart shows the number of times a particular square is chosen in a random selection of squares. So the chart would change after each iteration or random square was chosen. I am looking a routine that would have 100s of thousands of iterations and thus the vertical bar chart would be changing 100s of thousands of times. I do I do this? I looked at the sample creating the vertical bar chart, but not sure how I update the chart after each iteration. Be sure to answer in very simple terms. I am a novice trying to learn how to do charts in WPF and C#. Thanks

Hello Communicate, i'm stucked a little bit, it's a very simple thing actually, but i can't find it. I have changed the default legend to have a bit formatted on my chart, but what i can't do is getting a bit more space between two entries. Can anyone assist on this? My current Code
<lvc:CartesianChart.ChartLegend>
<lvc:DefaultLegend BulletSize ="25" FontSize="{Binding Source={x:Static p:Settings.Default}, Path=FontSizeNames, Mode=TwoWay}" MinWidth="500" Padding="20" UseLayoutRounding="False" IsEnabled="False" TextOptions.TextFormattingMode="Display" HorizontalContentAlignment="Stretch" />
</lvc:CartesianChart.ChartLegend>

Good Evening, in the picture below you can see the edges (in red) of the graph graphic component, but the plot is actually smaller than the red margin (green edges). How can I get dimensions and coordinates of the green rectangle?
Thank you in advance,

Good night, i don't know in wich part you can see (or something related to) how to graph a Data Table of Sql, but in this case the data table is generated in real time. I need to use mappers.xy, the part of constant change or something like that?

(I already try to do it, the table generated in a using method, but when i tried to graph it, saving the data in a list, it doesn't work) (I reaally feel lost in this)

Have your tried it like this?
may that give you a hint. I use a Datatable to and filling my chart by converting the values per column into ChartValues
To update the chart you need to re-apply the Datacontext to the Datatabl
