Re: Understanding Steema.TeeChart.Chart component

Hello, It seems they are inter-changeable? Not really. WebChart derives from DataBoundControl and is a minimal implementation of it to enable the Chart class to export an image to it and so to appear on an ASP.NET WebForm.

Page_load is always called, but not the button code (only called when pressed) … so for every call first an empty p...

Re: Resize Not Working with Custom Axes (Regression)

Hello Kris, So, the bottom line here is that we provide the data in the exact same manner with both the v2009 and v2023 versions but the table jumps around with the latter when you change the height of the form where the TChart is located. That is the regression and what we need fixed. It could be a...

Re: yvalue datamember binding error

Hello, I think this maybe because you are trying to add a string to the YValues.DataMember when it expects a double value. To add a string value, please use the LabelMember, e.g. public Form1() { InitializeComponent(); InitializeChart(); } class Student { public string Name { get; set; } public doub...
