Steema Central

For further readers there is also a compromise option to create "steema.resources" resource-file at starting assembly location and put there a resource named "TeeChart" containing the license. Though it definitely not plugin-usage scenario. There is indeed the possibility of wrapping the TeeChart.l...

Our concern is that our class library could be wrapped in another class library with full licencing - and so without a watermark - only to be resold. This would be in clear violation of our license agreement. It is for this reason that the only publically available option, in the very exceptional ca...

Hello, I need to embed license not in a starting app assembly, but in dependency assembly which actually uses TChart. Even if you don't have access to the executing assembly, if you drop the TeeChart.licenses file into the same directory as the executable and the two class libraries (your wrapper cl...

Have you tried adding the EntryAssembly attribute to the AssemblyInfo of your non-exe assembly (A)? The gif here shows you how to do this (in the context of an ASP.NET app).

With your code all points are Blue (some of them should be Tomato or Gold as the corresponding lines are):

Ah, so you don't want all the Pointers to be of the same color? In which case, change the following line:

Code: Select all

 oldColor = line1.Pointer.Color = Color.Blue;

to this:

Code: Select all

oldColor = Color.Blue;

But when I uncomment that line (where I manually change line color to Blue) - all point are Blue despite I'm setting every point color explicitly in the Add function: In this scenario there is no need to complicate matters with the series color at all, i.e. public partial class Form1 : Form { priva...

That's because you're adding in point colors to your series: lineActualData.Add(i, Values[i].ActualValue, Values[i].FlightDate.ToString(dateTimeMask) + " " + Values[i].FlightShift + " " + Values[i].FlightNum, lineActualData.Color); lineEquivalentData.Add(i, Values[i].EquivalentValue, Values[i].Fligh...

You could try using the Parent property, i.e. private void TChart1_ClickSeries(object sender, Series s, int valueIndex, MouseEventArgs e) { var tchart = sender as Chart; var parent = tchart.Parent; MessageBox.Show(parent.GetControl().Name); }

Looks like it's working now, many thanks. You're welcome. Could you explain please, why that collection has more items despite of the fact that I've added _count points? The Value field is public but is for internal use. If you are uncomfortable using it, you can use the more standard API calls: Li...

I'm asking because for example the ticket id=2221 has already been fixed in new build ( Steema.TeeChart.NET 4.2019.8. but .NET Core assemblies were not updated.

As you correctly point out, this is because the TeeChart .NET Core assemblies are still in pre-release.

Hello, okay, well, another variation on an earlier technique seems to work in these circumstances, i.e. public partial class Form1 : Form { //max visible labels private const Int32 maxDisplayedLabelsForBottomaAxis = 20; List<string> _labels = new List<string>(); int _count; public Form1() { var rnd ...

So how to deal with that? Is there a way to disable automatic thinning that is performed by chart itself?

Try setting the Labels separation to zero, e.g.

Code: Select all

            tChart1.Axes.Bottom.Labels.Separation = 0;
            tChart1.Axes.Bottom.Labels.Style = Steema.TeeChart.AxisLabelStyle.Text;

And now I cannot dispose that Labels collection until my application closes. You don't have to use the Labels collection, unless you want to. I've also modded the code so scrolling doesn't draw every label when less than 20 labels are shown: public partial class Form1 : Form { //max visible labels ...

How can I determine labelIndex inside DrawAxisLabel event? I've tried e.LabelValue - but it is always 0 in my case.. Well, you could check the incoming Text with the Labels collection you already have, e.g. public partial class Form1 : Form { //max visible labels private const Int32 maxDisplayedLab...
