Hello! still not sure about this one - maybe it's the values in your data[] object, becuase when I use code such as this: private void InitializeChart() { var rnd = new Random(); var line1 = new Line(_tChart.Chart); var day = DateTime.Today; for (int i = 0; i < 100; i++) { line1.Add(day, rnd.Next(1,...

The line is composed of continuous points. When I zoom the chart, duplicate numbers appear on the axis. How should I avoid this situation. You can set the ValueFormat of series points and axis label values to any of the Standard or Custom numeric format strings, e.g. private void InitializeChart() ...

While I am using TeeChart 3.5, it seems to be a the same issue you are seeing. Was hoping to hear if this issue was resolved.

As I explained in my last message, this is not a TeeChart issue (an issue pertaining to an app component), but is an issue of the configuration of the app itself.

Another thing related to vertical lines. When I zoom in I got this non equal spacing axis lines (see red lines which are bigger), How do I make sure these has the same spacing.

How are you adding values into your series?

I created a 3D chart using IsoSurface. It can run smoothly when 1000 points are loaded, but when I append to 3 million points, the rotating chart is not smooth. How should I optimize it. Here I'm using this code: private void InitializeChart() { _tChart.Aspect.View3D = true; _tChart.Aspect.Orthogon...

As soon as I run this: chart.Axes.Bottom.Minimum = 0 chart.Axes.Bottom.Maximum = CurrMaxPoints It zooms back out. I want it to stay focused on the same area of the graph. I'd have to see more of your code to have a clear understanding of what's going on, but staying focused on the same area of the ...

Inverted legend also has inverted scrolling Is it possible to get inverted legend without scrolling affected. You could try something like this: private void InitializeChart() { var line = new Line(_tChart.Chart); for (int i = 0; i < 100; i++) { line.Add(i); } _tChart.Legend.FirstValue = line.Count...

I already figured out 2 and 4.

Great! Not sure about 1) and 3) myself - could you please give me a code snippet which reproduces the Chart with these problems so I can have a look at it?

Thank you for responding. I tried to enable the minorgrid

What happens when you add in all the code that refers to Grid and MinorGrid on the bottom axis? DrawEvery is set to 2 by default; maybe it's 1 that you need.

Apologies for the lateness of this reply. In TeeChart we have a Grid and a MinorGrid for each axis - so code such as this: private void InitializeChart() { var line = new Line(_tChart.Chart); line.FillSampleValues(); var bottom = _tChart.Axes.Bottom; bottom.Grid.DrawEvery = 1; bottom.Grid.Color = Co...

Apologies for the delay in our reply to your question. You're best bet would be to use the Canvas Events - the following is a screenshot from the Feature Demo on GitHub : TeeChartNetExamples_2020-06-09_10-42-31.png You can use these canvas events to draw anything to the chart - lines, shapes (circle...

Just to let you know that a new version is available here:
https://www.nuget.org/packages/Steema.T ... .2020.5.25

which resolves this issue.

Hello Hermes,

apologies for this issue - we have been able to reproduce it here and will upload a rebuild to NuGet in the near future.

we still have problems on activating "Pinch to Zoom" in the WPF version of TeeChart. Can you explain how to activate? What problems are you experiencing? If I remember correctly the tests we made back in 2018 using a touch screen (not a tablet or phone), activation happened automatically. I have a ...

Hello Amol, you can see the code working by downloading the NuGet package from here ; you can either use Visual Studio to install the package or you can download it and unzip it to access the TeeChart assemblies. The SubAxes feature may not be a feature available in TeeChart 2012, but I am not autho...
