I can't see what is working incorrectly here. When you zoom in first time and number of currently displayed points is lower than 20 (in your gif from point 11 to point 19) every label on bottom axis should be drawn (because 19 - 11 < 20). In your gif every second label is drawn. That is because of ...

Okay - first off, LastVisibleIndex is one off in LIne series because the line itself is considered as belonging to the next point - so, for example, if you scroll the chart so there's only one point visible, the visible part of the line which continues to the next point (which isn't visible) causes...

rather than using the Zoomed and UndoneZoom events, have you tried using the AfterDraw events?Here this works much better. For unzoomed chart both values are correct: https://i.ibb.co/PhVVgYh/0.jpg But for zoomed chart LastVisibleIndex returns correct_value + 1: https://i.ibb.co/yhCtb7r/1.jpg https...

If your license does not have 'teechart.winform' listed it won't work either. Obtaining a new TeeChart.licenses file with 'teechart.winform' listed is easy to do by requesting one from sales@steema.com with your license details. 'teechart.winform' is not listed. I will contact sales@steema.com, tha...

Hello. I'm using TeeChart Pro 4.2019.8.8 and I need to determine indexes of the first and last point that are visible to user. I'm using line1.FirstVisibleIndex and line1.LastVisibleIndex, but it gives me strange values. I use non-historical horizontal zoom. First zoom: https://i.ibb.co/Syn7Swb/1.jp...

The licenses.licx is unnecessary for TeeChart.NET Core as this file is only relevant to the Windows Forms designer and the Web Forms designer - in TeeChart.NET Core you can delete it. In near future, when WinForms designer will be added to Visual Studio 2019, whether it will be necessary to add thi...

We have created a new build for TeeChart.NET Pro and have uploaded it to NuGet - the new build is Steema.TeeChart.NET 4.2019.8.8 and you should see it here within the next hour or so as the NuGet site updates.

With version 4.2019.8.8 it works as expected, thank you.

Hello. I have a teeChart .NET Professional 2018.12.17 and my goal is to show a tooltip with point index when cursor hovers above bar point (and to hide it when cursor is not above any bar point, i.e. cursor is above any empty space on chart). I've tried the following code: private void bar1_MouseEnt...

Hello. I'm not from Steema team but looks like I know what to do :) - handle GetLegendText event, something like that: private void tChart1_GetLegendText(object sender, GetLegendTextEventArgs e) { //some checks (e. g. series index) if you need it if ((e.LegendStyle == LegendStyles.Series) && (e.Inde...

Hello. I have a teeChart .NET 2018.12.17 with a legend with enabled checkboxes (Legend displays SeriesNames). How can I: Remove some of checkboxes (I need to have checkboxes only for several series, not all of them)? Series.ShowInLegend=false is not suitable for me because I need to have SeriesNames...

Hello again. Latest Visual Strudio 2019 still not have WinForms designer in .NET Core :(, so I've performed a deeper test: Downloaded TeeChart.Winform (https://www.nuget.org/packages/Steema.TeeChart.NETCore.WinForm/) Installed .NET Core preview 6 (because .NET Core preview 7 only works with Visual S...

Re. 1. Zoom. The property forms part of the preview and is private. We can look to opening up the Previewer to code, so that some defaults can be set before opening it. Re 2. Grid Pen With respect to Axis Grid. It seems that 'special' line pens, dash, dot etc, scale differently to solid lines. A so...

I've performed a quick test - everything is going fine for now..
It's really hard to work without WinForms designer in .NET Core - expecting VS team to add it soon. After that I'll be able to peform full testing.
Thank you for your job.

Any progress for now? Is there a new version to test?

In the meantime, the current TeeChart NetStandard version can be used as a non-forms control - please find following an example of the use of TeeChart.NET Standard in an ASP.NET Core app: http://www.teechart.net/files/teechartnet/201904TeeChartMVCNetCore2.zip Unfortunatelly ASP.NET Core app is not ...
