Bar chart hatch styles issue

Visual Studio 2022,
.net6.0,
Steema.TeeChart.NET.Business (5.2022.9.26)
Having issues with giving a single bar in a series a hatch style. I've included a minimum working example, where each generated image (53 in total) each look identical (matching the image provided below).
Code: Select all
foreach (HatchStyle hatchStyle in Enum.GetValues(typeof(HatchStyle)))
{
TChart barChart = new TChart();
Bar bar = new Bar();
bar.Add(10);
bar.Brush.Style = hatchStyle;
bar.Brush.Color = Color.Red;
bar.Brush.ForegroundColor = Color.Blue;
barChart.Series.Add(bar);
// Export specifics
var png = barChart.Export.Image.PNG;
png.Width = 550;
png.Height = 550;
png.Save(@"C:\Users\...\HatchStyle" + hatchStyle + ".png");
]

Hello,
sorry for the delay in our reply. I think your result is expected, as for each loop you are creating a new instance of TChart. If I run the following code:
Code: Select all
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
InitializeChart();
}
private Steema.TeeChart.Styles.Bar bar1;
private void InitializeChart()
{
foreach (Steema.TeeChart.Drawing.HatchStyle hatchStyle in Enum.GetValues(typeof(Steema.TeeChart.Drawing.HatchStyle)))
{
bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
bar1.Add((int)hatchStyle);
bar1.Brush.Style = hatchStyle;
bar1.Brush.Color = Color.Red;
bar1.Brush.ForegroundColor = Color.Blue;
}
tChart1.Header.Text += $" version {Steema.TeeChart.Utils.Version}";
}
}
}
I get what I think you expect:

Hi Christopher,
I am using a standard .net application format, so I am not too sure what the parent class "Form" would look like. I use a main method to run application, in my case, with the code I gave above wrapped inside.

These styles have now been partially implemented in the
latest TeeChart Pro/Business NuGets. The following code:
Code: Select all
var bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
bar1.Add(10);
bar1.BarWidthPercent = 100;
bar1.Brush.Style = Steema.TeeChart.Drawing.HatchStyle.BackwardDiagonal;
bar1.Brush.Color = System.Drawing.Color.Red;
bar1.Brush.ForegroundColor = System.Drawing.Color.Blue;
tChart1.Header.Text += $" version {Steema.TeeChart.Utils.Version}";
var png = tChart1.Export.Image.PNG;
png.Width = 550;
png.Height = 550;
png.Save(path);
new Process
{
StartInfo = new ProcessStartInfo(path)
{
UseShellExecute = true
}
}.Start();
Now gives us:

This is a partial implementation, each implementation of a HatchStyle was much more time consuming that we had originally appreciated—if you find a HatchStyle that is not implemented but that you wish to use, please tell us and we will implement it for you.
