Bug when changing series type?

I think I might have found a bug. In our app the amount of data points range from 50 to 200 000+ and the chart never bucks under it. Performance is understandably "not super fast" with 200 000 data points, but acceptable. But when changing type from (fast)line to bar, the component hangs, it doesn't...

Changed property?

I wonder if there is (I couldn't find anything in the features demo) that can tell me if the chart object with series etc has changed? What I mean is this: A user loads one of our reports. He adds a series to the chart, not using the chart editor. He closes the report. I want to ask him if he wants ...

Series.ChangeType() question

We are using the v 2.0.2179.21171 build at the moment and as far as I can see a series loses its Axis when doing a ChangeType on it. Earlier a series lost most, if not all, properties when doing a change of series type on it, now this seems to be the last "issue" with it. What I do is that I have a ...

How do we make sure that the references are resolved properly when building then? That might seem like a basic question but I can't see how that would work, considering this: I have TeeChart installed on my machine for development. I set references by actually selecting the DLL - but since I have it...

Licensing issues

When reading the tutorial 17 on licensing it seems clear to me that the steema chart component has to be installed on the machine where you build your application, is that correct? I get that impression from the fact that you need to have a registry key set for the license to be able to compile into...

Group several variables on X-axis?

I will try to explain what I want to do with the purpose of finding out if this is doable in an easy way. What I want to do is to have a series with some values for Y and with several variables linked to it's X, probably as labels. What do I mean with several variables? Well, imagine that you have d...

Yes, that worked nicely, but what I really want to do now is to limit the number of types available when changing the series type from the ChartEditor, is that possible? When the user clicks "Change" in that main window, he can change the series to basically any type available. I would like for him ...

Aah, the bliss of reference problems. I discovered that instead of running the latest debug build I was running the version prior to that (at least). You have fixed a couple of the issues I had discovered, like the inability to hide the Data tab, SeriesDatasource etc. That is all working nicely now ...

Limiting choices in Chart Editor

There are a couple of features in v2 regarding the control of available options for the users in the Chart Editor. I am trying to use these and have some questions, of course. 1. Using the, as far as I can tell, undocumented feature of ChartEditorOptions I can control the visible buttons in the Main...

Marks.Clip = true could be sufficient but I still have the problem with changing the series type with that strategy, don't I? Or are all properties transferred when a series type is changed? Event handlers are not, as far as I can tell. My problem is this: The user can choose what column from a data...

I do what you need. You really don't need to do a lot. Lets say you have three columns a, b and c. When you create your chart each series will have something like this: a.YValues.DataMember = "a"; a.YValues.DataSource = yourdatatable; As you can see there is very little you need to do here! I save t...

But is there a way to identify the new series if for instance the user has changed the type from the Chart Editor? The problem, as I see it, is that I can have n number of series and the user might change the typ of one of them, n2 for instance. If I loop through all the series I will add event hand...

How to handle marks outside and change of series type

I have the problem with marks for a series being displayed outside of the axis on bar series. I found this workaround: private void line1_GetSeriesMark(Steema.TeeChart.Styles.Series series, Steema.TeeChart.Styles.GetSeriesMarkEventArgs e) { if ((series.XValues[e.ValueIndex]<tChart1.Axes.Bottom.Minim...

DateTime and DbNull Values

Hi there, everybody. Using the 2.0.2078.14844 build of TeeChart v2 I discovered some more problems with DbNull values. I managed to get it to display the label for a certain point as stated in a previous thread here. Well, now I discovered that when using DateTime values from a DataTable as XValues ...

I got it working now and the last problem I had, with version 15119, was that the e.ValueIndex always was -1 and that the labeltext always was set to just the numerical value of its position. This made it impossble to set the label to something useful from the dataset. What I noticed was that these ...
